Z coordinate management ( altimetry) #74

Closed vpicavet closed 8 years ago

vpicavet commented 8 years ago

The altitude ( z coordinate) is stored inside QgsGeometry objects. We can access it via an expression z($geometry)

The z coordinates of vertices should now be displayed and editable in the node tool dock. It does not seem to work with the PostGIS driver.

I've just tested in the last master, and there is "Vertex editor" dock widget that allows to edit thz Z coordinate of a node. Successfully tested on two postgis tables with 3D points and 3D linestrings

3nids commented 8 years ago

main problem is when creating new features, not editing. If you have create geometry column using postgis 2 (ALTER TABLE...ADD COLUMN) and not v 1 (AddGeometryColumn), you can't commit the feature.

Indeed, reproduced. I am on it
