Spatial join and fieldmappings

BryceGardner1 — Thu, 12 Dec 2013 16:44:16 GMT

I have two feature classes that I am attempting to join. One is a point feature at the intersection of streets, the other is the streets line feature. I am using spatial join to create a new point feature that has the names of the streets as an attribute for the points. I know how to do this through the tool within ArcMap, but the code is a different matter. I have explored all the help through spatial join and fieldmappings, but it just doesn't make sense to me.

In the tool I create a new field, 'NAMES' and assign the streets names that intersect each point to that field, separating separate streets with a '&', using the windows in the tool. The tool makes simple work of this, however the code to make this happen is much more complex. Here is what I have so far.

#4. spatial join     fieldmappings = FieldMappings()     fieldmappings.removeAll()     fieldmappings.addFieldMap('NAMES')          SpatialJoin_analysis(dissolve_int, dissolve, spatial_join, 'JOIN_ONE_TO_ONE', '', fieldmappings, 'INTERSECT', '5 FEET')

I can't seem to figure out how to tell the program to assign the street names from the streets line feature to this new field and separate them with a '&'.

I know this is more advanced, but any help is appreciated.

Thanks,

Bryce

Hi Bryce,

In ArcMap, run the spatial join tool with all parameters set and then open your Results window (Geoprocessing menu > Results). Right-click on the completed tool > Copy as Python snippet. You can then paste this into your IDE and see the correct syntax.
