Great Circle Distance Batch Calculator

This tool for ArcGIS version 10 allows for the input of an unlimited number of origin/destination latitude, longitude pairs in CSV format, and calculates the distance between the origin and destination for each pair using the great circle distance formula (the shortest distance between 2 points on earth).  Created by CGA intern Brian Bettenhausen.
