[GRASS-user] problem in projection of shape files

[Jamie Adams]

I would use ogr2ogr <http://www.gdal.org/ogr2ogr.html> from GDAL to
reproject using a proj4 string.  For example to wgs84:

ogr2ogr -s_srs "+proj=tmerc +lat_0=0 +lon_0=90 +k=0.9996 +x_0=500000
+y_0=-2000000 +a=6377276.345 +b=6356075.41314024 +units=m +no_defs" -t_srs
wgs84 out.shp in.shp
