| GSJ Open-File Report, no. 442 | August, 2006 |
We have been engaged in the research on aeromagnetic survey.
During the course of our work, various softwares were developed, and
some of them are so versatile that its publication will be beneficial
to another people.
Here the library software consisting of many subprograms is reported.
This report is a revised version for the previous GSJ Open-File Report
no. 400 (Nakatsuka, 2003). The points of revision are
1) addition of perspective (oblique grid) representation in
coutour/color-grading map,
2) improved data precision of coastlines, rivers/lakes, and prefecture
boundaries,
3) repleted utility program including BATCH process support,
4) known bugs were fixed,
5) provision of manual HTMLs.
This library 'libgm' consists of versatile subprograms coded in C
language, with proper interfaces with FORTRAN language.
There are 13 subprograms listed bellow, and each has multiple entry point
names to realize various function systemtically.
In the Geological Survey of Japan, a library software called "GSJLIB"
(Nakatsuka et al., 1986, 1990) was developed, and the ideas in it are
also succeeded in our library. The subprogram calculating IGRF is taken from
the report by Nakatsuka (2005).
Manual ducumentations by Adobe Systems Inc. (1990, 1994) were
informative for the coding of subprograms generating PostScript output.
All subprograms are coded in C language, and the filenames of
sources have .c (specifier) extensions.
There are also HTML documentations (manual) how to use the library
subprograms.
The trailing E.html (specifier) indicates English documentation HTML,
while those without "E" are in Japanese.
Some utility programs are also stored as an appendix.
All the contents of this report are stored in a CD-ROM with
a tree structure bellow.
In actual environment of utilizing the software, the directories
lib, prog
and data are assumed to be stored under
the directory path of /home/SHARE.

Manual ducumentations how to use this library from a FORTARN language program are included in this report in the form of HTML files. As the further detail adjustment or advanced use of the libarary might be possible from C language program, a brief documentation on the prototype definitions and the summary of functions is provided. The explanation of the miscellaneous utility program (appendix) is also available.

This library includes the subprogram WSHORE drawing coastlines,
rivers/lakes, and prefecture boundaries. This program assumes that the
coordinates values of coastlines etc. are stored in the
'/home/SHARE/data/shore' directory.
In this open-file report, the data from authoritative institutions
bellow have been re-constructed into smaller files under
the 'data/shore' directory, with a reduced accuracy,
which can be used easily by adjusting directory location setting.
The resolution of actual data included in this report is 0.01 minute
in latutude and longitude for larger scale drawing, and 1 minute for
smaller scale.

Shorelines and Administrative Boundaries data from "Digital Map 25000
(Spatial Data Framework)" by the Geographical Survey Institute, Japan
