https://communities.sas.com/t5/Graphics-Programming/SAS-Geospatial-Capabilities/m-p/23403#M652 SAS has several geospatial capabilities, built-in and otherwise. <BR /> I'll list a few below ...<BR /> <BR /> SAS/Graph ships with many geographical maps (such as a world map, maps of each continent, and maps of most countries, and US maps by state &amp; county), and "proc gmap" can plot data on these maps in several ways (such as choropleth maps that color each map area based on the response data values).<BR /> <BR /> "proc mapimport" can be used to import shape-files into SAS maps that can be used by "proc gmap".<BR /> <BR /> We have "proc geocode" which can estimate the latitude/longitude of addresses, and once you have lat/long coordinates, you can annotate markers on a map at those locations (the marker shape/color/size can be controlled).<BR /> <BR /> We have "proc ginside" to tell whether a point is inside of a map area (for example, is a certain lat/long value inside a given state in the US map ... or you can create your own map polygon for a circle of a given radius and determine which points are inside that circle).

For instance, if I have data that include geospatial coordinates for each record, can I perform operations that require spatial capability, such as, "sum all variable x for county a" in which county a is a shape?<BR /> <BR /> Sorry if this sounds vague. I have a contractor who is proposing PostGIS as an alternative solution to SAS, and I am wondering what geospatial capabilities SAS might have of which I am unaware. It seems like the basic capability is ability to use geocodes in the data, and to use shape file information with those geocodes. <BR /> <BR /> I'm going to bet that the capability is another layer, not a part of SAS, per se, but something based on a relationship between SAS and ESRI. ??
