ISU Drill-Down v. 1.0. Determines the z-values of a raster at point coordinates.

  Instructions:
The program consists of two independent parts: to create a random point file of points within a polygon and a drilldown to determine the raster z-values at point coordinates.

  To Create Random Points File:

  • Enter a value for the number of points to create
  • Select a polygon file (only a single polygon allowed within the polygon file) to determine the boundary of the points created
  • Enter a field name to create for z-value data storage
  • Click "Create Random Points"

      To Drill down to a Raster:

  • Select the point layer file
  • Select the raster layer into which you want to drill
  • Enter a field name to store the drilldown values
  • Click "Compute Drilldown"
