[Gvsig_english] error loading big shapefile

[Juan Lucas Dominguez Rubio]

Hello. Just to quantify what we mean by "quite big", you can run this to see a summary of your large shapefile (sorry for the ugly syntax). Simply replace the two occurrences of "myfile" and send the output to the list. That will give us an idea:
 
ogrinfo -geom=SUMMARY myfile.shp myfile | awk '{ if (NR <= 10) print; if ($1=="POLYGON") { pol++; vert=vert + $3; if ($3 > maxv) maxv=$3; } if ($1=="LINESTRING") { pol++; vert=vert + $3; if ($3 > maxv) maxv=$3; } } END { print "========="; print "POLYGONS OR LINESTRINGS: " pol; print  "VERTICES: " vert; print "MAX VERTICES: " maxv;  }'
 
 
(perhaps I forgot something and it'll need some small changes)
Regards,

Asunto: [Gvsig_english] error loading big shapefile



Dear list,
when loading a quite big shapefile into gvSIG, I get the following error message. It seems not to crash the application, but still, I am a little bit confused. I specified -Xmx2000M in gvSIG.sh. I would be happy, if someone could explain the error message of gvSIG

Best,
Wolfgang
