I have recently used ArcGIS and prior to this I have no experience with it. I wanted to calculate the distances between Care Homes in England to NHS hospitals. Basically I wanted to see how many Care Homes were there within a radius of 10 km to each hospital. I used the point distance method and in the options menu in the search radius option I specified 10 kilometers.
This is the resultant table that I get.
My query is the distance column are expressed in all decimal representations and therefore I don't think they are in km. For example, the distance between INPUT_FID 0 and NEAR_FID 20168 is 0.08618273742. In terms of kilometers, the distance between their coordinates however is 7.880
Do you have any explanation as to why this discrepancy arises?
