Showing Student Population Densities
I want to make a map that shows the density of geocoded students in such a way that is similar to a dasymetric map but that does not require all the extensive prep. Data that I have to work with are geocoded students, street centerlines, school attendance areas, parcels with zoning, and study areas that break up the attendance areas to residential neighborhoods.
Mapping Center Answer:
A dasymetric map is a complicated map to make since you are generating new output areas that did not exist before you started. That said,
- There is a script that was written for ArcGIS 9.2 by Rachel Sleeter that help with dasymetric mapping: http://geography.wr.usgs.gov/science/dasymetric/data.htm
- Or you can implement the steps themselves in ArcGIS as specified in a paper by Jeremy Mennis at: http://astro.temple.edu/~jmennis/pubs/mennis_pg03.pdf
- Or you can use some easy to basic dasymetric steps as described by Mitchel Langford: Mitchel Langford, "Rapid facilitation of dasymetric-based population interpolation by means of raster pixel maps". Computers, Environment and Urban Systems 31(1): 19-32 (2007).
If none of these work for you, and you want to make a map that is not dasymetric, let us know!
