comment NetworkAnalyst seems to solve along straight lines but not intersections
This didn't lead to any changes, still no route/distance between points that are connected by vertex vs. end points.

I haven't tried this yet, but it seems like point location on the network is not a problem. Will try and update in a bit.

If by single line you mean a single line for each road vs lanes, then yes. This is a simple country wide road network that is only being used to calculate distances and not anything fancy like lanes, uturns, etc.

your response is much appreciated. I would really like to see error handling, particularly in what is reported to the user, improve in ArcGIS. More informative errors are needed, with the option to get even more detailed information if desired. Again, thank you to ESRI for taking the time to respond.

Wouldn't these slight changes in the pretty print name or the decimal positions you mention be present in the .prj file that's exported with the Save As option? If so why does diffing prj files show nothing? I had wondered if slight differences in the x,y resolution could be causing the conflict as well.

I wish I had time to run down every little quirk I run into w/ ArcGIS, often I just have to live with it and find the next least pleasant workaround. I used Data Management -> Copy Feature to copy into a new feature class (temp named), deleted old feature class, renamed new feature class to match old. Using ArcGIS shouldn't require a degree in software testing. =(

Thank you, ammended question in response. My feature class's data source info does not contain a Linear Unit field.

comment Why does ArcGIS “forget” my specified default GDB for a map document (mxd)?
I am running tools inside of ArcMap, both from the toolbox and the Python window. The workspaces are not set to the wrong values, its just every so often it just stops respecting the workspace and then starts outputting to the default location (in documents/ArcGis/default.gdb). I've found that reseting the workspace variables via the Python window seems to fix this.

comment How do I calculate a weighted centroid with respect to a raster, e.g. population weighted centroid
I see - I'm actually using a raster that tries to do exactly what you mentioned - distribute the population precisely over the entire area. GPW, GRUMP, UNEP, LandScan are examples of this. Since I do have the actual (or predicted rather) population at some resolution, I don't use the density. Now, assuming I did what you did, where there is only one value of the polygon, doesn't that result in simply the centroid being the typical geometric center? Final twist, if I get a weighted centroid that's outside of its associated polygon, does this entail data issues, or is this possible?
