I have a contour data file downloaded from UK Ordnance Survey, which gives 2d contours of an area in gml format (also supplied in .shp format) with the heights of each contour attached to the attributes of each line.
I want to give the contours a Z value of the height attribute attached to it, so that I have a 3d contour file I can then use in QGIS to create hillside shading etc, and potentially export to dxf/dwg.
Is there a way to do this without manually moving each line?
I was hoping for an actual tool I can use, as I have no script experience - I am willing to learn this if necessary, but would appreciate it if any answers that might refer to scripting please be as patient as possible, as I am clueless with where to even start to run a script!
I'm using QGIS at the minute but also have access to ArcGIS 9.2 (though none of the add-on program packages, just basic ArcMap.)
Thanks - Lisa
