Closest facility solver

PurposeThis sample is an application that shows how to programmatically perform a closest facility analysis. You will learn how to load facilities and incident locations from a feature class, set solver parameters, execute the analysis, and get back the output results.

How to use

See How to use ArcGIS samples for help on compiling, setting up the debugger, and running the sample.

Data has been provided for your use with this sample. It can be found at <Your ArcGIS Developer Kit Install directory>/Samples/data/SanFrancisco/SanFrancisco.gdb.
If the sample has associated data, you will find that the sample's zip file includes a "data" folder alongside the language folders. However, you will need to update the sample to point to the location of the data once you have extracted all the files.

  1. Start Visual Studio to build and run the application.
  2. In the application, click Find Closest Facilities to perform the analysis. The ordered list of facilities appears.
  3. You can change the impedance attribute, use one-way restriction, and use hierarchy.
  4. You can change the target facility Count and CutOff values.
