Rich, You can interpolate the data using v.surf.idw to get a raster map. Literature says that a power parameter superior to 2 (between 3 to 5) might get better result for rainfall. Laurent 2016-10-12 12:20 GMT-05:00 Rich Shepard : > On Wed, 12 Oct 2016, Laurent C.

[GRASS-user] query highlight too persistent

2016-10-12 Thread Dave Roberts
In GRASS 7.3.svn (and maybe earlier) querying a polygon in an wx device with your mouse highlights the polygon in yellow. However, the highlight is too persistent, i.e. a d.erase does not make it go away, although the render map icon will clear it. --

Sorry, not having a good day. This message below was not intended for GRASS. However, the message that should have been here (to keep the thread from breaking) ogrinfo filename.GDB says that some layers in this file are multi-polygon. However, when I use v.in.ogr on the same file they

Thanks Helmut. v.build did not help, as the topology was already OK. The problem seems to be that the database has come unconnected. To make a long story short 1) I used v.in.ogr on a GDB directory, which produced a single feature with 20 layers, only a few of which had spatial data 2) to
