I understand you would load directly from GPS without any human action, so starting from an empty dataset. You load the first polygon, after loading the second polygon you like it would be changed accordly to the first polygon, after loading another polygon you like it would be changed accordly with the first and the second polygons, and so on... This could be work if the GPS is a really good differentially gps, and not a simple hobbist GPS because it could change the polygon due to man environmental situation (rain, fog, etc..) and could be happened the third polygon is good meanwhile the first and the second are not so quality good. -- ----------------- Andrea Peri . . . . . . . . . qwerty àèìòù -----------------
