I am trying to implement a python script that creates in a first step a Network Dataset and that in a second step gets a point feature class for which the tool should create for each feature in the feature class a service area. The first step is no problem, but the second...

My first idea was to use the cursors in python which should run through the whole attribute table. For each feature a temporary feature class should be created which should be used as input for the service area.

Is this the right direction or is there an more easy way to calculate for each feature individually a service area?

You can use the Make Service Area Layer, Add Locations, Solve, and Save to layer file geoprocessing tools to generate service areas for multiple input features (e.g. a point layer with geocoded addresses). This is analagous to the workflow using the ArcMap GUI described in the Service area analysis help topic.

  • But is it also possible to create for each facility an shapefile that shows the service area? – Sven Jan 10 '13 at 20:33
  • @Sven The output of the service area analysis is a polygon shapefile like the one shown above. You can export this to a regular shapefile. – dmahr Jan 10 '13 at 20:37
  • I know, but I want that the script creates for each facility an service area shapefile. Regarding your example I will have at the end 5 shapes. One for each facility. Is this possible? – Sven Jan 10 '13 at 20:45

    Yes you can, after you calculate the output service areas, you can use my answer here to split it by atribute (in your case a Id atribute of your locations) – Alexandre Neto Jan 10 '13 at 21:19
  • Thanks, Alexandre! But how can I reach the the results layer "polygon" to split the service areas? The Service Area layer consists of several sub-layers: facilities, point barriers, lines, etc. I want to reach the result layer "polygons". Is there a way in python? – Sven Jan 11 '13 at 06:52
  • Is it like this "Service Area\Polygons"? – Sven Jan 11 '13 at 07:02
  • @Sven see the second image in my post. You can export the Polygon layer to a new shapefile. – dmahr Jan 11 '13 at 13:45
