Hi all,

I'm struggling to find a way to measure the distances among many polygons in a vector map, the measure need to be taken between the boundaries. I had a look to Rgeos manual and seems that gDistance could solve my problem. My only concern is if gDistance calculate an euclidean distance or a geodetic distance. I mean, is the distance corrected for the projection used? If yes, whatever projection is fine?

Thank you

Luca
