However after much trial and error I am still unable to access the elevation data in other modules (e.g. v.to.rast). There is always a requirement to specify the attribute - and as you can see, the geotmetric data are not attributes and do not show up in the menu of attributes. Here's the output from a query that may help visualize the problem: east, north: -79.7630759471, 39.0874586371 DBT@corH: Type: Line Id: 885 Length: 275.746 Line_height: 698.602997 Layer: 1 Category: 885 Driver: sqlite Database: /Users/sesMacBook/grassdata/KML/corH/sqlite/sqlite.db Table: DBT Key_column: cat Attributes: cat: 885 cat_: 885 tessellate: -1 extrude: -1 visibility: -1 What I need is the Line_height value, which is not an 'attribute' - neither is it 'z' I tried exporting the file as a shape file and reimporting it - same result. Then as a GRASS ascii - no file created - and ran out of ideas. Is there a way to add Line_height as an attribute? Any help appreciated...I would try v.to.db with option start, then v.to.3d
It would probably be nice, and IMHO not too complicated, to add line height as an option to v.to.db. Stuart, I invite you to post an enhancement request on the trac [1] for that.
