the title seems weird though, i am dealing with Japanese shapefile and it has its own "bizarre" projection.
I have two hints to solve this issue.
- it's based on espg 4301 (http://pacificprojections.spc.int/4301#)
- but the coordinates is in integer(?), it has to be transformed. for instance, the coordinates divided by (3600*1000) e.g.) 502888725, 128444858 => 139.6913125, 35.6791272
Within QGIS, it looks like i need to make custom CRS and fix proj.4 of ESPG 4301, which looks like below (i added +to_meter = 1/3600000)
+proj=longlat +ellps=bessel +towgs84=-146.414,507.337,680.507,0,0,0,0 +no_defs +to_meter=1/3600000
but obviously, it doesn't work.
Can anyone help for this?
when i define the projection to ESPG 4301 and open the file in ArcGIS, it shows the error message of extent issue.
