comment How to convert self intersecting polygon to multipolygon?
Can you count the occurrences of XY's > 1 to find the touching point, excluding the start/stop points? Then split the list at that Point to generate distinct polygons?

comment How to convert self intersecting polygon to multipolygon?
Maybe you can test for this self intersecting condition using OGR IsValid() or IsSimple() and then Buffer(0.0) to write out correct geometries.

comment How to find boundaries with Fuzzy logic and GIS
@Kirk, I would experiment using different buffer distances. BTW, the ArcGIS Union tool has a nice Gap feature, specify NO_GAPS, there will be no inner gaps in the polygons. I've seen this buffer & dissolve technique used several ways to produce Oil/Gas Well Field outlines from Well locations.

comment Polyline will not turn into a feature layer via MakeFeatureLayer_management (arcpy)
You don't need to run MakeFeatureLayer for Geoprocessing tools such as Clip, Buffer,etc. Just pass in the pure polyline geometry.

comment How to make a one part polyline from a multipart polyline?
"Unsplit Line" requires an ArcInfo license. If you do not have this license level then use "Dissolve", it has an Unsplit Line option.

comment Ways to measure similarities/congruence of tracks (point features) in ArcGIS
What do you mean by "Similar"? Miles per week run? Time of day trained? Total Elevation run? Or the same physical run (street, trail, etc) in common?

comment In an ESRI Shapefile, what is the “Record Number” field of each record header in the .shp file?
This sentence is incorrect, "The one-to-one relationship between geometry and attributes is based on record number" The relationship cannot be based on record number because the .dbf has no record number. The relationship is purely by position. The first shp record, whether is has a record number of 0 or 1 is related to the first dbf record.
