As these are essentially points on a grid, Mike would like to calculate the distance between any two given latitude/longitude points. The forum cannot guess, what is useful for you. This uses the ‘haversine’ formula to calculate the great-circle distance between two points – that is, the shortest distance over the earth’s surface – giving an ‘as-the-crow-flies’ distance between the points (ignoring any hills they fly over, of course!). For example, if both input and near features have 1,000 points each, then the output table can contain one million records. Therefore, the distance of the plane from the origin is simply given by (Gellert et al.
