I have two features: points and grid cells (vector). I want to select a point within a grid cell (some cell do not have point) using python script and create a new feature layer with below conditions:

  1. If no point in cell then leave as it is.
  2. If only one point then pick that point.
  3. If more than one point then calculate average point.

How can I achieve this task ? I will appreciate your help.

Thanks.

    What software do you have available to use? ESRI? QGIS? PostgreSQL? – dklassen Feb 5 '14 at 22:05

If you have ArcGIS - you can do the following - use the arcpy.InterpolateShape_3d() tool to get the value of the raster for each point - then use the arcpy.Statistics_analysis() tools to get the mean value for each raster value.

  • Thanks for your advice ! points and grid cells both are vector actually.Sorry for confusion. – GeoSpal Feb 5 '14 at 22:16
  • Then you just need to do an Intersect of the points with the polygons - then the statistics again to get what you want. Same process, just different tools/approach. – dklassen Feb 5 '14 at 22:18
