I'm working with only a basic/student license for ArcGIS 10.1 on an ocean mapping project.
I've created a grid that covers all ocean area, capturing various characteristics within that grid (the grid is now in point data).
I now need to add the distance from each point to the edge of various polygons (shipping lanes, countries) but need geodesic distance because of the large distance covered.
I read that if you keep the data in a geographic coordinate system, unprojected, the distances generated through various measuring tools in ArcGIS automatically measure in geodesic.
Is this true, and if not, is there a way to force geodesic measurements in various tools?
