Calculate routes

Question

Hello, I am new to this community, so I hope my Question ist placed in the right postion:

Due to one of my companie's projects, I have to calculate routes between two points. No problem if I have two points and two feature classes. But I have one feature class with just one point and another with multiple points. So now I have to calculate the route from the single point to each of the other points seperately, using a Python script.

Any idea to solve this?

You can create a FeatureSet from any two Features and pass it to the find_routes function, so you can iterate over the features in your multiple-points feature set and create a new 2-point feature set along with the start feature. Here's an example where I use a single feature set and select one point as the start and find routes to the other points: from arcgis.gis import GIS from arcgis.features import FeatureLayer, FeatureSet from arcgis.network.analysis import find_routes gis = GIS(username='name', password='pass') # get 4 cities cities_layer = FeatureLayer('https://services.arcgis.com/P3ePLMYs2RVChkJx/arcgis/rest/services/USA_Major_Cities/FeatureServer/0') cities = cities_layer.query( where="NAME IN ('Santa Clara', 'Sunnyvale', 'Milpitas', 'Cupertino')", out_fields='FID, NAME', out_sr=4326 # feature points must be in lat/lon ) # set the start city start_city = cities.features[2] start_city.set_value('FID', 0) # routes are calculated in order of IDs, # so set start city to smallest ID routes = [] for end_city in cities.features: # skip if start city if end_city.get_value('FID') == 0: continue start_end = FeatureSet([start_city, end_city]) routes.append(find_routes(stops=start_end)) for r in routes: print(' ' + r.output_directions.df.RouteName[0]) print(r.output_directions.df[['Text', 'DriveDistance']]) ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
