[OSGeoJapan-discuss] Integration of Japanese GIS formats into mainline GDAL ?

[Nobusuke Iwasaki]

Akagi-san and all,

Thank you for the information and contribution not only GDAL-FGD but
also many useful QGIS plugins.
I could convert Japanese FDG to shpape files. It is very useful!!
I will check that it is possible to convert old Japanese FDG files with GDAL.

Best regards,
Nobusuke
