Geo clusters in SAS

[sassy7]

I would like to cluster a geo map using the k-means cluster algorithms, or another cluster algorithm: my scope is identify clusters based on geographical location that have similarites between a specific attribute/s: the clusters obtained are a combination of location and a KPI. There any methodology or procedure I could use in SAS?

Hello,

I think you need something like "Spatially constrained hierarchical clustering".
No idea how to do that in SAS though.

SAS has Density-based spatial clustering of applications with noise (DBSCAN) but in DBSCAN that space has no geographical connotation.

I think you need to program it.

Maybe you can use the SPP procedure (?).

The SPP procedure performs analysis for spatial point patterns in two dimensions.
