I am trying to create a map with a layer of county tax assessor property parcels plus NED elevation data.
The projection of the tax assessor layer is a weirdo -- looks like user-created by the county. I got the NED layer to change to that weirdo projection, or so I thought.
But when I go to intersect the NED layer with the tax assessor layer, I always get the "CRS of the layers did not match" warning, and the resultant new layer is empty.
I've tried using GRASS to re-project the NED layer, but cannot figure out how to do it that way either.
What should I do? I just want to use the parcels layer to intersect (like clip) the NED layer.
The tax assessor parcels layer gives this as its projection:
+proj=lcc +lat_1=37.06666666666667 +lat_2=38.43333333333333 +lat_0=36.5 +lon_0=-120.5 +x_0=2000000 +y_0=500000.0000000001 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=us-ft +no_defs
In the "Project Properties" window, it is listed under the heading "User Defined Coordinate Systems". What is it? And how can I get it to jive with the USGS NED data (which is, I think, unprojected and based on datum NAD83)?
Is "projection" in this QGIS usage the same as CRS?
