Hi all I'm working on coastlines in antarctic area and i would like to edit a coastline which is in a vector file .evf to make it fit the coastline of a geotiff, and after editing, export the coastline in an ascii file made of to columns (longitute and latitude for each point). Until now, i manage doing this by exporting my vector file to a ROI and then, from ROI to ASCII, but in the file i get, the points don't appear in the right order. It seems that the image and vector are scanned and the points are stored in this order whereas i want the points to be stored in the "line order". Could someone help ?
