Intermediate Level Services
This level of services is comprised of tasks associated with non-nested data construction, research design issues, the use of global positioning systems (GPS) and/or wireless devices, customized programming, and advanced ESDA.
Example: Customized programming is the development of a spatial segregation program in ArcGIS that can calculate different segregation indices. Also, the GIA Core has applied hotspot analysis. The existence of hot and cold spots provides strong evidence for spatial autocorrelation, and it suggests the use of advanced spatial analysis methods is warranted which would yield unbiased estimates, and appropriate inferences.
