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?

why use the density rather than actual counts?

thanks - I'm familiar with these settings - the issue I'm seeing is in spite of. See my edit above - hopefully it makes it clearer.

comment Is it possible to use Arcpy in ArcGIS 10 to zoom to a selected feature?
Most scripting functionality that handles document (mxd) management, display, or output is going to use the ArcPy mapping module. help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/…

has anyone actually used this to debug arc scripts though?
