Usage Tips and Constraints

Population Density values must be in people per square miles. When used with NLCD land cover, make sure that class values are in their original format (e.g. 11, 21, 22, 23, ... 95) When creating in Excel Custom Coefficients Table, make sure that the Coefficients Column is in "Number" format before saving it as DBF. Population Density values must be in people per square feet. New PI field name must be unique and have 10 characters or less. ETIS returns IS values of negative 1 (meaning that IS value was not processed):

  • if some of the polygons overlap each other
  • if the polygon is not completely covered by the land cover grid
