Hi community, I'm trying to convert my 3 vector points to raster points. The aim is to use this raster points as input for r.surf.nnbathy.
I created a region with following command: g.region --verbose vect=gfa_niep_work@PERMANENT nsres=1 ewres=1 This is the output of the region: projection: 99 (Transverse Mercator) zone: 0 datum: potsdam ellipsoid: bessel north: 5699460 south: 5698740 west: 3328920 east: 3329940 nsres: 1 ewres: 1 rows: 720 cols: 1020 cells: 734400 In the next step I used v.to.rast with following commands: v.to.rast --overwrite --verbose input=gfa_niep_work@PERMANENT type=point output=gfa_niep_rast use=attr column=werte The metadata are these: +----------------------------------------------------------------------------+ | Layer: gfa_niep_rast@PERMANENT Date: Thu Mar 22 11:49:26 2012 | | Mapset: PERMANENT Login of Creator: danny | | Location: Test | | DataBase: /home/danny/GIS | | Title: Labels ( gfa_niep_rast@PERMANENT ) | | Timestamp: none | |----------------------------------------------------------------------------| | | | Type of Map: raster Number of Categories: 0 | | Data Type: DCELL | | Rows: 720 | | Columns: 1020 | | Total Cells: 734400 | | Projection: Transverse Mercator | | N: 5699460 S: 5698740 Res: 1 | | E: 3329940 W: 3328920 Res: 1 | | Range of data: min = 5.89 max = 5.89 | | | | Data Source: | | Vector Map: gfa_niep_work@PERMANENT in mapset PERMANENT | | Original scale from vector map: 1:1 | | | | Data Description: | | generated by v.to.rast | | | | Comments: | | v.to.rast input="gfa_niep_work@PERMANENT" layer=1 type="point" outpu\ | | t="gfa_niep_rast@PERMANENT" use="attr" column="werte" value=1 rows=4\ | | 096 | | | +----------------------------------------------------------------------------+ My problem is now that i get only 1 raster point with the value 5.89 instead of 3 points. The correct range of the values should be min: 1.853 max: 5.89 What did i wrong?
