Python: select by Location and assign value from the source to the target

rf2

Hi All

I have a polygon layer with a 'lot' field and a points layer. I would like to use python to select the points by location (to find what points are contained in what polygons) and assign the value in the 'lot' field from the polygon layer to the point that is contained in the relevant polygon feature. Not sure how to create that link between the 2 layers...

Any help is much appreciated.
Thank you

There are 3 ways I can think of:

1) Use arcpy to spatially join the lot attribute from the polygon to the point.

2) Use ArcPy to convert polygons to points and keep the attributes.  The points will be populated with the Lot values.

3) Use ArcPy to Select By Location, then calculate the point field values to equal lot number from the selected polygon feature; then use iterations of this process for each polygon in your feature class. 

In my opinion I'd go with option 2 because it's the easiest. Option 3 is probably a more of a "learning experience".


Have fun!
