Python and Geometry

[neilwebster]

Hi All,

I'm trying to find a tutorial on using the Geometry and Cursors but I can't find anything.  Can anybody point me in the direction of one?  All I've been able to find are the ESRI presentations saying it's possible.

I'm trying to do something like the below code extract:

for row in arcpy.da.SearchCursor(poly, ("OBJECTID", "SHAPE@")):
 if row[0] == 82:
  geom = row[1]
  for point in arcpy.da.SearchCursor(point, ("SHAPE@")):
   pgeom = point[0]
   pgeom.intersect(geom,1)
   
   **DO SOMETHING BASED ON THE INTERACTION OF THE POINT/POLY**

Thanks

You may find this presentation useful. There is simple explanation how to access geometry by cursor.

Thanks, I had seen that.  I was after a more detailed description.

OK. This presentation + online arcpy help
(http://resources.arcgis.com/en/help/main/10.1/index.html#/Reading_geometries/002z0000001t000000/  - reading;
http://resources.arcgis.com/en/help/main/10.1/index.html#/Writing_geometries/002z0000001v000000/ - writing)

Is all I got. Can you specify what exactly you want to achieve? Maybe then we could be more helpful 🙂

Best Regards.

this latest python group blog post also deals with creating geometries and the examples use cursors: http://arcpy.wordpress.com/2012/09/14/building-feature-classes-from-numpy-arrays/
