KML Macro: Integrating SAS and Google API and Its Application in Mapping Manitoba's Health Data on Google Earth and Google Map
Source: University of Manitoba
Google API allows developers to overlay their own customized maps on Google Earth and Google Map. It means that it is possible to colorize a map based on an estimated or known measure. This requires putting the geographical coordinates along with statistical data together in a specific XML file format called KML. This paper introduces KML macro (written by the author) that uses SAS to quickly and easily create such a file in one step by a SAS user who does not need GIS knowledge or additional software. Also, it will be shown how to create an appropriate coordinates file for this macro in SAS format.
