Both variables are zonal means. The average distance to the nearest facility is the zonal mean of the Euclidean distance grid (based on the facilities). The average number of facilities is the zonal mean of a one-kilometer radius focal sum of the facilities grid. (This is merely a grid whose cell values count the number of facilities within each cell. ...

Your database is not really a SpatiaLite database but a SQLite database which contains geometries which are encoded according to FDO specification. Something about FDO can be read from http://trac.osgeo.org/fdo/wiki/FDORfc16. Some other software, like TatukGIS, are also creating SQLite databases with FDO geometries. Spatialite can read FDO geometries ...

I would approach this as follows: Convert your polygons into lines (by which each edge of the polygons - a line between the consequent vertices - will become a line feature in the output feature class.) After the conversion, the output lines will preserve their "parent" polygon ID. Use GP tool: Feature To Line. Take each point and then find out which line ...

Agree with Chris W. This field calculator expression will calculate from and to measures in a point file, providing there is a single river - polyline: def CalcFromToMeasures(shp,n): mxd = arcpy.mapping.MapDocument("CURRENT") lr=arcpy.mapping.ListLayers(mxd, "river")[0] with arcpy.da.SearchCursor(lr, "Shape@") as cursor: for row in cursor: ...

If I understand your question correctly, it sounds like you are trying to plot the relationship between size of wetland and distance to your sample points. I don't think there is a single tool that will do what you want in one step. The Near tool in the Proximity toolset will calculate the closest distance to the other feature. The point distance tool will ...
