[Gvsig_english] gvsig mobile- unable to edit shapefile

[Juan Lucas Dominguez Rubio]

Hello, I don't know if you can see that info in gvSIG.
 
You can guess it by comparing the size of the .shp file after the intersection I described:
 
- If the resulting .shp file is about 30% smaller than the original, then you have converted a 3D shapefile to a 2D shapefile.
 
- If the resulting .shp file is 40-50% smaller than the original, then you have probably converted a 4D shapefile to a 2D shapefile (4D shapefiles are even rarer than 3D shapefiles).
 
- If both .shp files are the same size, then the original was a 2D shapefile.
 
In this case, the original shp file was 2.58 KB and the resulting shp file was 1.8 KB (decreased by 30.2%)
 
You can also get that info with FWTools ( http://fwtools.maptools.org ). It's a set of command-line programs. One of them is ogrinfo, this is its output:
 
====================================
C:\Program Files\FWTools2.4.5>ogrinfo GCS_ggl_SHP.shp
INFO: Open of `GCS_ggl_SHP.shp'
      using driver `ESRI Shapefile' successful.
1: GCS_ggl_SHP (3D Line String)
====================================
