I am using ArcMap 10.2.
I have two layers- one is around 2,000 geolocated ballot boxes while the other is around a dozen geolocated facilities. I would like to calculate the total distance between each ballot box and all dozen or so facilities. For instance, Ballot Box 1 is 10km from Facility X, 15km from Facility Y, and 20km from Facility Z, and so on. So Ballot Box 1 would be assigned a score of 45km. I'd like to calculate this score for all 2000 or so ballot boxes.
So far, I've used the point distance tool where the ballot boxes are the input features and the facilities are the near features, left the search radius blank, and ArcGIS produces a table, with a "DISTANCE" column populated, so it seems to have worked. My question is threefold:
- Is this the correct procedure?
- In what unit is this distance reported (Projections are UTM, so I assume it defaults to meters?)
- If I leave the "search radius" blank, does ArcGIS default to figure the distances in the layer's full extent?
