comment Split Lines at Intersection of Other Lines
gene; as per my above comment, the Union in OpenJump is not working as expected (in fact it is doing nothing.) I also noticed that there are multiple Union commands (which is bizarre). Can you walk me through that step? How is Tools>Analysis>Union/Dissolve/Merge command different than Tools>Geometry Functions>Union (Function)? Neither of these seem to make sense based on any "Union" command I have used in other software.

comment Split Lines at Intersection of Other Lines
gene; can you walk me through this? I can't actually seem to perform a Union of the two line layers in OpenJump either--it just does nothing, presumably because it is also expecting a polygon layer as one of the inputs.

Care to expand on that with a possible solution?

comment Split Lines at Intersection of Other Lines
gene; unfortunately, v.overlay is expecting an area for one fo the layers as well. As per the manual: "v.overlay allows the user to overlay two vector maps. Features in ainput can be lines or areas and are cut with areas in binput."

comment How can I create/draw “freehand” polygon features in QGIS 2.2?
What OS are you running? How did you install QGIS 2.2? I just tried on my Windows7 system, with QGIS2.2 installed via OSGEO4W and it worked fine. Are you sure you have a polygon or line layer, and that it's editable?

comment How to avoid snapping errors in QGis?
I rarely use the snapping settings in meters--I find that pixels makes more sense. If you measure your small differences, are they less than 1.5 meters, or greater?

comment How to determine if an object is a circle
Thanks; you're right, and that makes sense! I guess the difference was how many digits of pi used - I only used a couple digits!
