It is often difficult for an analyst to determine the next step in an analytic process or to visualize how various techniques and tools fit together. Using the below as a list of the common GIS operations the analyst might use:

  • Data discovery and entry
  • Data conversion
  • Data validation
  • Spatial data management
  • Attribute data management
  • Data visualization
  • Data processing/analysis
  • Output of maps and reports

The Structured Geospatial Analytic Method (SGAM) provides the means to relate the analytical step to the Structured Analytic Technique (SAT) and then to the appropriate geospatial operation. The following table summarizes this mapping:
