I now have a working vector file that displays correctly and can be queried
with normal results. 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...
