Hi! I am working on sea polygons once again. After reading through the many generate-sea-related topics I am still not sure what the current state of the art is on the matter. - What is the current recommended command line option/combination that works for you? What other techniques do you need? I have e.g. read about manual adjustions to the data in some posts. Or did it not work for your area at all? - What level of confidence do you achieve with generate sea? Many posts still mention minor failures, disappearing islands etc. - Is it possible to save the resulting sea/land polygons for later re-use? Apparently the OSM data changes more frequently than the actual coastline and re-generating it from scratch every time you update is not necessary. It would be helpful to keep the sea data around, especially if you had to do manual adjustments to create it. But I have not read about such a feature. Did I miss something? thanks Nop -- View this message in context: http://n2.nabble.com/State-of-the-coastline-art-tp4829364p4829364.html Sent from the Mkgmap Development mailing list archive at Nabble.com.
