I have a shapefile with regolith (soil) data that I would like to use as a categorised raster (say 007_1ASC) in Maxent.

The regolith data is in the following files:

007_1.cpg 007_1.dbf 007_1.prj 007_1.sbn 007_1.sbx 007_1.shp 007_1.shx

Using Qgis, how can I get this into an ASC file with categorised data?

  • When I look at the attribute table the columns are labelled: gid, regid, regcode, narrative The regcode is the value that I need to be reflected in my categorised data. When I I go into the 'rasterize' dialogue I can select 'Attribute field' set to 'gid' or 'regid'. How can I select 'regcode'? – SteveResearch Jun 17 '16 at 20:17
  • I think the answer may be to change the string values for the 'regcode' to an int value. I will try this and update the question. – SteveResearch Jun 20 '16 at 13:00
