st: merging raster and vector GIS data

I would like to obtain elevation data by US Census Block. The Census Bureau does not provide such data and refer one to the US Geological Survey, but as far as I can tell, the USGS does not provide data matched by Census Block. On-line searches yielded no such data. So I think I would need to merge the USGS raster data on elevation (National Elevation Dataset - http://ned.usgs.gov/Ned/index.asp) to the Census Bureau's Tiger shapefiles.
I believe that one can do this in ArcGIS and other software packages, but I was curious about whether it is possible to do this using Stata. Existing (and very helpful!) user-written Stata programs either work with raster data (-ras2dta-) or shapefiles (-shp2dta-), but as far as I can tell there is no user-written Stata program that brings data from these two different formats together.
So my questions are:
1. Am I correct that there is no user-written Stata command(s) that can merge raster and shapefile data into a Stata dataset?
2. If there are no such commands, is there interest (other than my own) in having such a command?
3. Am I crazy to contemplate trying to write such a command? (This last question is mostly rhetorical.)
