This report is a fully-revised and expanded version for the previous GSJ Open-File Report no. 519 "Software system for Aeromagnetic data processing, Grid data manipulation, and Reduction and quantitative interpretation of magnetic anomaly data (2)" [Nakatsuka, 2009f], with adding newly developed programs (ANAMX) of higher sophisticated analysis methods such as 3D imaging interpretation and Generalized crossover analysis of aeromagnetic data. Also, this report includes an update of Library Software (GSJ Open-File Report no. 518 [Nakatsuka, 2009e]).
We have been engaged in the research on aeromagnetic survey, and developed various kinds of programs for data processing, analysis and interpretation. The outlines of them have already been reported on the scientific journals and at the scientific meetings [Nakatsuka and Okuma, 2005b, 2005c, 2006a, 2006e, 2009a, 2011, 2014; Nakatsuka et al., 2009c; and others : see 'References' section]. Their source codes are open to public through the GSJ Open-file Reports.
In this report, We deal with six groups of programs for the aeromagnetic
survey, as follows.
(1) DPAM:
programs for aeromagnetic survey observation data processing,
(2) GDMP:
programs for grid data manipulation,
(3) ANAM:
programs for analysis of magnetic anomaly data,
(4) ANAMX:
programs for 3D imaging and generalized crossover analysis of
aeromagnetic data,
(5) libgm:
library subprograms for geophysical analysis and graphic presentation,
(6) utils:
miscellaneous utility programs.
This software system is in a style of program libraries, consisting of many
individual programs of rather simple functions.
Then the actual process to some target/objective would require a series of
program executions.
The data formats used in this system are customized for our own original
style.
However, as for its design, all data are handled in the form of ASCII text,
so that the user can easily convert data to/from another style of formats.
Among six program groups, (1) DPAM, (2) GDMP, and (3) ANAM are the succession from the GSJ Open-file Report no.449, while (4) ANAMX are the lately developed programs for higher sophisticated analysis methods. (5) libgm, and (6) utils are the newest updated version for the GSJ Open-file Report no.400 "Library Software for Geophysical Data Processing and Representation", but be aware that there exist some major changes of specification.
DPAM group consists of programs for aeromagnetic survey data processing as follows.
| alog2asc daq2asc bdaq2asc dmaq2asc |
xldam xldpn xldhg filtadasc |
despike dvcorr ecomp fcomp |
ggrid ggrids xslin xslina |
pframe pltrk pchkdv |
pchkmag pchkres pchkcomp |
Programs alog2asc, daq2asc, bdaq2asc, and dmaq2asc converts aeromagnetic raw acquisition data (specialized for our survey system) into common ASCII file format. alog2asc / daq2asc correspond to the stinger type survey system of (old) AIRLOGS / (newer) AMDAQ, bdaq2asc for bird type survey, and dmaq2asc for newly developed multicopter (drone) or some other mobile surveys.
Programs xldam and xldpn generate line data (DPAM line data) file from aeromagnetic ASCII raw data, making use of Real-time GPS and PostNav processed DGPS position data, respectively, and the program xldhg generates similar line data (HGAM line data) file from helicopter-borne gradiometer aeromagnetic data acquired. In addition, xldam, xldpn and xldhg also calculate the IGRF residuals. The program filtadasc was newly added to suppress high frequency noise caused by helicopter, when such situation occasionally took place.
The program despike eliminates spike noises in magnetic field values (total magnetic field and IGRF residual) of DPAM line data, the program dvcorr performs the diurnal correction of magnetic field data making use of Ground-Station magnetic field data, and the programs ecomp and fcomp execute the compensation of aircraft's magnetic effect for compensation flight DPAM line data and for survey flight DPAM line data, respectively, using the method described by Nakatsuka and Okuma [2005c].
The programs ggrid and ggrids generate grid data from random points data (i.e., DPAM line data or equivalent) by using the method of "continuous curvature splines in tension" as developed by Smith and Wessel [1990]. Only the magnetic field (IGRF residual) data are converted into grid by ggrid, while ggrids applies the method also on the altitude data. The programs xslin and xslina extract simple standard line (StdLIN) data from random point data. Various formats of random point (line) data are supported by xslin as input data, while xslina deals with only DPAM line data but with the function of averaged re-sampling.
The program pframe draws an illustration of coordinates framework of
survey area for easier setting of grid location parameters, program
pltrk plots trackline paths from DPAM line data, and program
pchkdv plots the ground station magnetic data to reveal the diurnal
magnetic variation.
The programs pchkmag, pchkres and pchkcomp are
used to plot magnetic field data in order to inspect the data quality.
Total magnetic field data is plotted in black by pchkmag, and IGRF
residual data is plotted in blue by pchkres, while pchkcomp
plots IGRF residual magnetic data both before and after the compensation of
aircraft's magnetic noise in red and blue colors.
GDMP group consists of programs for grid data manipulation as follows.
| sel seldb seldb2 gtopo |
adjlv gadd gsub gtrim |
govlay gojoin gmerge txproj |
altchg gtrf altx rearx |
plmap plmapc plmapl plmapcl |
plmapg plmaps plmapcs shade |
xplmap xplmapc xplmapcs |
The programs sel, seldb and seldb2 generate new grid data from an existing grid data with re-gridding. For sel program, the existing grid data should be assigned as the input filename parameter, while grid data from "Aeromagnetic Database of Japan" [Geological Survey of Japan, 2005a] * (AMDB) is selected by the code-name input for seldb, and data from "The compilation of magnetic anomalies at a smooth surface of 1,500m above terrain by using the Aeromagnetic Database of Japan" [Nakatsuka and Okuma, 2009b] ** (AMDB2) for seldb2. Program gtopo generates grid data of topographic elevation from "DEM40" data *** (Digital Elevation Model 40m).
| * | AMDB grid data must be stored under the directory /pub/AMDB/DATA/ defined by AMDBDIR parameter in the seldb.f90 source (survey area data within subdirectory grd, and district data within subdirectory reg), and filenames must be "code.gd", where code is small letter filename of original. | |
| ** | AMDB2 grid data must be stored in the directory (/pub/AMDB2/DATA/) defined by AMDB2DIR parameter in the seldb2.f90 source, and filenames must be "MMNN.mgc", where MMNN is the primary mesh code of the correponding area. | |
| *** | DEM40 is a group of topographic elevation data files, reconstructed from Digital Maps (50m mesh elevation, Japan-I, Japan-II and Japan-III) by the Geographical Survey Institute (GSI). Refer to "How to generate DEM40 data files" genDEM40mE.html. Data files must be stored under the directory (/home/SHARE/data/DEM/dem40/) defined by DEMDIR parameter in the gtopo.f90 source, and divided into subdirectories 'Z??' corresponding to its UTM zone number ??. [If older version DEM data (wm40) is prepared already, see the description at the bottom of Section 4.] |
The program adjlv adds a constant value to all grid data in order to adjust DC level, the program gadd adds 2 sets of grid data, and the program gsub subtracts the 2nd file grid data values from the 1st set grids, to generate a new grid data. The program gtrim replaces values of input grid data with NULL (undefined) data value for the range where the values of reference (2nd) grid data are NULL data value, to generate a new grid data.
The program govlay overlays multiple grid data sequentially with placing slit zone, the program gojoin joins multiple grid data sequentially with placing transient zone surrounding the overlaid data, and the program gmerge merges multiple grid data sequentially with placing transient zone along overlapping zone, to create a new grid data. The program txproj translates grid data into another map projection with re-gridding.
The standard format magnetic anomaly grid data file also include the information of the observation surface altitude, in the form of second set of grid or as a constant elevation value in the header part of magnetic anomaly data. The program altchg changes the altitude information of magnetic anomaly data, by replacing only altitude information. The program gtrf translates IGRF residual grid data into another reference IGRF model. The program altx extracts the altitude information into a standard grid data form, and rearx extracts the selected set of grid data from multiple sets grid data file.
The programs plmap, plmapc, plmapg, plmaps, plmapcs and shade produce illustrations of 3D surface given as altitude distribution of grid data, by line contour map (plmap), color-graded contour map (plmapc), gray-scale grading map (plmapg), shaded-relief contour map (plmaps), shaded-relief color-grading map (plmapcs) and shaded-relief map (shade), all on an A4 sheet. The program plmapl generates line contour map with drawing trackline paths, and the program plmapcl generates color-graded contour map with trackline paths, both on an A4 sheet.
The programs xplmap / xplmapc / xplmapcs create line contour map / color-graded contour map/ shaded-relief color-grading map of grid data, respectively, with adding various supplementary items on a selectable size of sheet up to B0.
ANAM group consists of programs for the altitude reduction and quantitative
interpretation of magnetic anomaly data as follows.
| emag amag cmag plamag plamagc |
emagf amagc cmagf calmas |
tmcorr tmcfix lcecorr aaptdp galtf |
emeq ameq ameqc cmeq galts |
emeqs ameqs ameqsc cmeqs rpmeqs |
edeq adeq adeqc cdeq |
edeqs adeqs adeqsc cdeqs rpdeqs |
The programs emag, emagf, amag, amagc, cmag and cmagf are used for the magnetization intensity mapping [Okuma et al., 1994a; Nakatsuka, 1995]. First, emag / emagf calculates the contribution coefficients matrix COEF, then amag / amagc executes inversion process of magnetization intensity mapping by the method of conjugate gradients (CG), and cmag / cmagf may be used to calculate the synthetic magnetic anomalies on a desired altitude surface by using the result of amag / amagc. The source model is approximated into rectangular blocks in emag / cmag, while the surface undulation is considered in emagf / cmagf. The iteration of CG method is controlled by the number of loop count (amag) or by convergency tolerance (amagc). The programs plamag / plamagc plot the result of the magnetization intensity mapping in the form of line contour map / color-graded contour map, respectively, with masking the surrounding source region.
The program tmcorr executes the correction of topographic effect on the magnetic anomaly grid data, assuming a uniform terrain magnetization, while the program tmcfix executes the correction of topographic effect with the assigned value of terrain magnetization. The program lcecorr estimates the railway loop-current effect in the observed magnetic anomaly grid data, and correct for it. The program aaptdp is for the semi-automatic modeling by point-dipole sources for observed magnetic anomaly grid data. These processes were used in the data interpretation of aeromagnetic data in the Kobe-Kyoto area [Nakatsuka et al., 2004b].
The program galtf interpolates observation altitudes of StdLIN data into grid data (for the purpose of illustrating observation altitudes), and the program galts generates grid data of smoothed observation altitude from StdLIN data (for the purpose of using as the reference in altitude reduction).
The programs emeq, ameq, ameqc and cmeq are for the altitude reduction from grid data, and the programs edeq, adeq, adeqc and cdeq are for the altitude reduction from random point data, by equivalent anomaly method [Nakatsuka and Okuma, 2005b, 2006a]. First, emeq or edeq calculates the contribution coefficients matrix CMUP or CFUP, and ameq / ameqc or adeq / adeqc executes inversion process of equivalent anomaly derivation by CG method. The iteration of CG method is controlled by the number of loop count in ameq / adeq, or by convergency tolerance in ameqc / adeqc. Then the reduction calculation is performed by cmeq or cdeq program.
The programs emeqs, ameqs, ameqsc, cmeqs and rpmeqs are for the altitude reduction from grid data, and the programs edeqs, adeqs, adeqsc, cdeqs and rpdeqs are for the altitude reduction from random point data, by equivalent source magnetization method [Nakatsuka and Okuma, 2005b, 2006a]. First, emeqs or edeqs calculates the contribution coefficients matrix CMUPS or CFUPS, and ameqs / ameqsc or adeqs / adeqsc executes inversion process of deriving equivalent source magnetization by CG method. The iteration of CG method is controlled by the number of loop count in ameqs / adeqs, or by convergency tolerance in ameqsc / adeqsc. Then the reduction calculation is performed by cmeqs or cdeqs program, and the reduction-to-pole anomaly on that surface is calculated by rpmeqs or rpdeqs program.
The program calmas calculates theoretical magnetic anomaly distribution on the specified observation surface, caused by a simple source model.
ANAMX group consists of programs for the 3D imaging analysis of magnetic
anomalies and generalized crossover analysis in aeromagnetic survey,
as follows.
| eimgd eimga fimgs fimgsc |
aimgn aimgnc aimgs aimgsc |
nimgn nimgnc nimgs nimgsc |
cimgn cimgnc cimgs cimgsc |
plsim plsimc plxim plximc |
plimv plimvc plmvarc |
exdeq1 exdeq2 exdeq3 exdeq4 |
axdeq axdeqc cxdeq genroff |
The programs eimgd, eimga, aimgn, aimgnc,
aimgs, aimgsc, nimgn, nimgnc, nimgs,
nimgsc, cimgn, cimgnc, cimgs, cimgsc,
fimgs, fimgsc are used for 3D magnetization imaging analysis
[Nakatsuka and Okuma, 2011, 2014a]. First, eimgd or eimga
calculates the sensitivity coefficients matrix CFIM and scaling coefficients
matrix FSCL, then one of the other 14 programs is used to perform 3D imaging
analysis of each regularizing condition preferred.
When CG method is applied to 3D imaging of quite many unknown
parameters to be solved, the least squares fitting solution tends in general
toward minimum norm solution, which leads the solution to a shallow
structure of magnetization distribution. To avoid this disadvantage,
parameter scaling is required. Program eimgd uses a parameter
scaling concerned with the source depth, and eimga adopts an
automatic parameter scaling with taking account of CFIM matrix character.
Now 3 types of 3D imaging analysis programs are available, depending on the selected regularization. aimgn, aimgnc, aimgs, aimgsc perform simple inversion with no regularization, and nimgn, nimgnc, nimgs, nimgsc perform minimum norm inversion, while cimgn, cimgnc, cimgs, cimgsc perform a inversion with minimum effective source volume (compact) constraint. Here, 4 programs in each type analysis correspond whether source elements thickness is considered at scaling (-s, -sc) or not (-n, -nc), and two method of iteration control [by loop count (-n, -s) or by convergency tolerance (-nc, -sc)]. In addition, fimgs and fimgsc are further modified version for cimgs and cimgsc, where magnetization values are forced to be within predefined range throughout iterative optimization.
Programs plsim, plsimc, plxim, and plximc visualize a vertical cros-section view of 3D imaging result. plsim / plsimc is for NS or EW section along the grid, and plxim / plximc is for arbitrary line segment section in any desired direction, each with line contours / with color-graded contour map, respectively. Program plimv / plimvc show the whole 3D imaging result in a bird's-eye view, with line contours / with color-graded contour map, respectively.
Programs exdeq1, exdeq2, exdeq3, exdeq4,
axdeq, axdeqc, cxdeq, genroff, and plmvarc
are used for the processing of generalized crossover analysis in aeromagnetic
survey [Nakatsuka and Okuma, 2006e; Nakatsuka et al., 2009c].
The principle of the method is an extension of edeq "Altitude
reduction from survey line data" introducing additional unknown
parameters describing mis-tie adjustment. That is, the inversion to
equivalent source anomaly and mis-tie adjustment is combined into
simultaneous equation, and solved with CG method.
First, exdeq1, exdeq2, exdeq3, or exdeq4
calculates the contribution coefficient matrix CXFUP. Program exdeq1
deals with constant level shift each survey line, exdeq2 accepts
linear variation for each line, and exdeq3 permits variations at all
cross-over point (linear between the points). Program exdeq4 is used
for the analysis of magnetic anomaly change between two time-epochs survey
lines crossing each other, similar to exdeq3 case but only one
epoch's parameter is variable.
Next, axdeq / axdeqc executes inversion process of CG
method to obtain optimum model of level shift. Then, cxdeq calculates
the altitude reduction result including cross-over adjustment.
For the case of exdeq4, program genroff converts the level shift (control point) data from axdeq / axdeqc into a random point distribution data (StdLIN form) of magnetic anomaly change. This random point data can be transformed to a grid data of distribution (e.g. using ggrid), and then program plmvarc is used to plot the magnetic anomaly change map (color-graded contour map) with illustrating control point distribution.

Descriptions of function and usage of each subprogram in the Library libgm are available through the page "libgm: Library Subprograms".
Following miscellaneous utility programs are available.
| cats cat4 cat8 |
crlf onlycr onlylf hdump |
cview cviewe uncview hdumpe |
qpencode qpdecode b64encode b64decode |
cxtw84 cxw84t igrfcal hgeoidcal |
utmcal xycal cxiken cxenik |
job job1 |
Programs cats, cat4, cat8, crlf, onlycr, onlylf, cview, cviewe, uncview, hdump, hdump, qpencode, qpdecode, b64encode, b64decode are simple programs to assist user's operation under the common environment of UNIX system. Programs cxtw84, cxw84t, igracal, hgeoidcal, utmcal, xycal, cxiken, cxenik support the usage of Library libgm subprograms, in such a way that the function of each individual subprogram is utilized interactively with dialog on a terminal.
Programs job, job1 are used to realize our own style of "Batch process" of sequential execution of various programs with assigning parameter data. This is intending an easy Job control language (JCL) as was utilized in the legacy "mainframe computer". Our system "AMSS3" of aeromagnetic data handling, reduction, analysis and interpretation is designed to match with this "Batch process", and if the source data and the job control file (plus preferably log file record of actually executed process) are saved, the completely same processing can be repeated easily.
We have developed these programs on a Linux system, on which the GNU Compiler Collection [http://www.gnu.org/software/gcc/] and one component 'gfortran' included in it are installed, and almost all programs are coded in Fortran90 language, except that those in libgm and utils groups and a limited number of programs/subprograms are coded in C language. The programs were developed step by step during the years of research activities on aeromagnetic survey at the Geological Survey of Japan, AIST and they were verified to function well by some practical data. Some programs, however, have been revised further for the improvement on reasonable data handling or easier operation. So there is a little possibility that some unaware bugs are left. But, we convince the user will easily correct bugs, as the source codes are presented.
In these programs, the subroutine library 'libgm' starting at Nakatsuka [2003] is utilized quite frequently. So, on this time update of software, the subroutine library 'libgm' (also updated a little) has been included in this report.
Most programs use some array variables, and the necessary size (dimension) of the array is dependent on the actual data to be dealt with. (Although too large size definition does not harm the correct result, the memory resource may be wasted, or program may not work because of memory shortage.) The definitions of such dimensions had been often given by using 'parameter' statement in source codes, to enable easier adjustment. Actually the definitions of such parameters was inconsistent among programs even in the same group. On this time software revision, rather new function of Fortran programing, dynamic allocation of array area was utilized. Then, even in case of requiring giant array, new programs can work without recompilation. Also, in this time revision, we used some other newer functions, such as free format coding, structured programming excluding statement number, C-like comparison operator, etc. As a result, some of the source programs cannot be compiled with old Fortran77 compilers.
When executing these programs, a few to several or more parameters have to be specified, along with selecting working directory path. In these programs, the LWKDIR (assist to set-up working dir. and process parameters, etc.) function with 'opnpin' mechanism of the subroutine library 'libgm' is implemented. The use of this function provides us two merits.
This report contains various points of renewal and augmentation againt
the previous version software. The most important point of augmentation is
the newly added group programs ANAMX performing the 3D imaging and
generalized crossover analysis of aeromagnetic data. Actually, there are
some programs (4 DPAM, 4 GDMP, and 5 utils programs)
newly added, but they are not so important but rather simple tools
useful.
Besides, a lot of existing programs were improved or revised during
the process of re-coding into Fortran90 style, but the basic functions of
them are unchanged even if the way of use or the function is a little
changed. And we didn't list up the minor change of specifications.
Such minor changes of specifications are reflected on the documentation
HTMLs of program groups.
This software system had a historical limitation of specification.
At this time full revision of software system, we made effort of mitigating
the effect of out-of-date specification, in two main points as follows.
[New Standard GRID data file Format v2018 and New Coordinate
Number]
In order to define 2-dimensional distribution of physical quantity,
grid data are frequently utilized. In our "Standard GRID data file Format",
the spatial position is identified by the combination of the coordinate
number indicating reference geodetic system and map projection type, and
the coordinates in that map projection. In the 20th century in Japan,
Japanese original TOKYO datum based on the Bessel ellipsoid had been used,
and later we moved to "Japanese Geodetic Datum 2000" (JGD2000) [= World
Geodetic System (WGS84)] after April, 2002. In that occasion, we assigned
coordinate numbers 200-399 for WGS system, with continued coordinate numbers
0-199 for existing TOKYO datum. Nowadays, however, it is common and
reasonable to use WGS basically. So, at this time full revision of the
software, we decided to move to the new definition of coordinate number:
0-199 is used for WGS, 800-999 for (old) TOKYO datum, and define new
"Standard GRID data file Format v2018" to enable converting old coordinate
number into new one automatically.
[Globalization in Filename naming convention of service data
files]
From the older version of this software, we prepared useful data
of Japanese Islands, such as location data of coastlines, rivers and lakes,
prefecture boundaries, and altitudes data of DEM and geoid. But, the
directory and filenames convention is specialized to the North-Eastern
Semi-hemisphere because of the location of Japan, and there was a
limitation that the data of Western hemisphere or Southern hemisphere cannot
be handled. At this time full revision of the software, we updated the
program and directory/filename convention to enable worldwide processing.
"Standard GRID data file Format v2018",
described in the Documentation for GDMP programs, seems there is little
revision. To be focused, however, are
(1) "4x,i4" in 1st Header format was "i4,4x" in old version, and
(2) the description on earth ellipsoid is transposed and
new coordinate numbers
are 0-199 for WGS, and 800-999 for old TOKYO datum.
There is redundant 4-column space in "1st Header Format", and it was
used to distinguish old and new coordinate number. Also, as GRID data format
other than the part of 1st Header is common between new and old format
description, users can convert old GRID data into new format v2018 quite
easily.
All programs included in this report are equipped with the automatic
distinction of old and new format, and old coordinate number is converted
to new coordinate number. Accordingly, users can use old Format GRID data
files as it is, only by giving new "coordinate number" parameter correctly,
if it is required.
The program revision for the globalization is so as to enable successful
program execution even in case of Southern Latitudes or Western Longitudes,
and the main point was re-definition of directory-filename convention.
If any parameter of latitude or longitude is to be read in, South Latitude
and West Longitude should be given as minus values. (If it is specified with
degrees and minutes, both should be minus. Usually program will only regard
[deg.Value + min.Value/60.] be the resultant deg.Value.)
As for directory/filename convention, DEM data read by gtopo
program and the shore data handled by wshore subprogram are the
files of [1 deg.Lat. × 1 deg.Long.] range each, and filenames are
related to the SW corner of the range (e.g., N33E135, S20E046,
N19W090, etc.), and files are stored under subdirectories indicating
its UTM zone number, in order to avoid too many files in a directory. Next
table shows the concrete examples of old and new filenames contrast.
| [Examples] | Old Filename | New Filename |
|---|---|---|
| DEM data |
wm40/33135.alt |
dem40/Z53/N33E135.alt |
| coastlines, etc. (WGS84) |
SW33/cst135.jpn |
Z53/N33E135.coast |
SW33/riv135.jpn |
Z53/N33E135.river | |
SW33/prf135.jpn |
Z53/N33E135.prefb | |
| coastlines, etc. (Old Tokyo datum) |
SH33/cst135.jpn |
t53/N33E135.coast |
SH33/riv135.jpn |
t53/N33E135.river | |

t53/N33E135.prefb |
Source programs coded in Fortran90 language have the filenames with .f90 (specifier) extensions, and those in C language with .c (specifier) extensions. To compile these programs under UNIX environment, @mkall script in each directory can be used, provided that the subroutine library 'libgm' is at first installed as the archive file libgm.a under the directory of /home/SHARE/lib, and the command names 'fort' and 'gcc' is aliased to (or the name of) the desired Fortran and C compilers. The executable program after compilation is stored in the directory /home/SHARE/bin with the name same as the source filename without the extension. It is recommended the users set their own environment variable PATH to contain the path /home/SHARE/bin, for comfortable environment of execution.
There are also HTML documentations for each of six program groups, DPAM, GDMP, ANAM, ANAMX, libgm, and utils. The explanation of the function of individual program is given briefly, and the parameters required to execute the program are described.
In the CD-ROM appended to this report, HTML files, Fortran90 and C source files, templates of Job Control files for non-interactive (Batch Job) execution, and TGZ archive files are stored, in the tree structure below.
===( Service data of Japanese DEM and coastlines etc. not included )===
[Data of Japanese DEM] DEM40 is a group of files of
terrain elevation data in Japan, extracted from Digital Maps (50m mesh
elevation, Japan-I, Japan-II and Japan-III) by the Geographical Survey
Institute, Japan (GSI) [Publication discontinued]. The source data are subject to GSI's copyright.
The procedure how to generate DEM40 files from GSI's Digital Maps is
presented in genDEM40mE.html. Data contents
are not included in this report, because it requires a procedure of
getting approval from the Authority (GSI). Data contents are not modified
in this time software revision, but only the file path names are changed
because of the globalization update. If old style data are existing,
a script file data/DEM/renewal_script
is useful to change file paths.
[Data of Japanese Coastlines etc.] The data of
coastlines, lakes and rivers, and prefecture boundaries of Japan are subject
to be changed the file path name because of the globalization update of
library subprogram "wshore", although the data contents are not modified.
If old style data is existing, a script file
data/shore/renewal_script is useful
