<P>I have been trying to compute the least cost to reach 1800 urban centres (destinations) from 432 different villages (origins) using the DEM file as cost information.</P><P>I would appreciate it if anyone suggests me an elegant way to compute the least cost to reach the destinations. </P>Wed, 21 Jul 2021 15:27:43 GMTWondmagegnTirkaso2021-07-21T15:27:43ZComputing the least cost between multiple origins/destinations

<P>Are you trying to calculate the optimal path from villages to urban centres using a road network? If so, Network Analyst is the right tool for that job. However, you need a road network, not a DEM. Here is a tutorial to get you started: <A href="https://pro.arcgis.com/en/pro-app/latest/help/analysis/networks/od-cost-matrix-tutorial.htm" target="_blank">https://pro.arcgis.com/en/pro-app/latest/help/analysis/networks/od-cost-matrix-tutorial.htm</A></P><P>But since you mentioned a DEM, does that mean you actually want the least-cost path through the DEM, like a watershed analysis? If so, this is not the correct forum. You should ask your question in the Spatial Analyst forum: <A href="https://community.esri.com/t5/arcgis-spatial-analyst-questions/bd-p/arcgis-spatial-analyst-questions" target="_blank">https://community.esri.com/t5/arcgis-spatial-analyst-questions/bd-p/arcgis-spatial-analyst-questions</A></P>Wed, 21 Jul 2021 23:08:27 GMThttps://community.esri.com/t5/arcgis-network-analyst-questions/computing-the-least-cost-between-multiple-origins/m-p/1081584#M7590MelindaMorang2021-07-21T23:08:27Z
