I'm wanting to create a service area within network analyst and want to input polygons as the facilities. However, I'm having trouble with this! I can input point features into the facilities, but am unable to do so with my polygon features. Can you only use point geometry as facilities within a service area analysis?

I believe you can only use points as facilities within your service area analysis. Depending on the context of your work, perhaps you could consider using the centroid of the polygons, the intersections of the polygon boundaries with your network dataset or perhaps which junctions of the network are located in proximity of the polygons?

  • Correct, only points can be used. Great suggestions about using polygons! – Paul Dec 12 '16 at 20:58
  • It's regarding accessibility to greenspaces in relation to a set of specific greenspace provision standards, so although centroids won't fully represent 100% true accessibility to the space, it'll be good enough for my project, thank you! – JGe Dec 19 '16 at 17:14
