Null Geometry ShapeFiles #326
This issue is related to, but subtly different, to the separate issue of multi-part and multi-geometry ShapeFiles.
Null geometries occur when a ShapeFile (can be point, line or polygon) has a record in the attribute table but not corresponding geometry. In the example below note how the attribute table shows 3 records but there are only 2 polygons in the map. This isn't because there's another polygon off the screen. It's simply that there is no third polygon.

GCD And Null Geometries
I have tested the following GCD features with ShapeFiles containing null geometries and everything works fine:
Linear Extraction Bug
I add the attached line ShapeFile as a new transect profile route without issue. However, when I attempted to perform a linear extraction using it I got the following exception on line 172 of Linear Extractor:
The GCD project that generated this exception is also attached to this issue.
