Sir: I am neither a computer nor GIS expert, although I eventually can figure out how to solve problems with computers; sometimes the long way around. PROBLEM: We draw all our maps in AUTOCAD. We have a fairly good "street map" which is based on our "tax map". The Tax map is really a collection of about 125 sheets comprising 10,000 parcels, varying scales, etc. We edge matched them and produced the street map as one layer but don't know how (or AUTOCAD won't let us) export it as a polygon shapefile. As it stands now, it comes out as a "line" shapefile. The last edition of the map was sent to a consultant who converted it to a "polygon" shapefile, probably using an ESRI product. That costs money that we don't have, and we want to do it a couple times per year. We use the Map with a database that is used for almost everything that I do as well as many other departments also. Once we get the base layer (polygons) we can do all kinds of GIS stuff with it, but we don't have a way to solve the only apparent problem that I think we have; namely: fixing overshoots and undershoots. No matter how good our line work is in AUTOCAD, when it comes out as a line shapefile, there are thousands (like about 18,000) over or undershoots. I have figured out how to fix the overshoots in OpenJUMP by using the "nodeline" tool, but I don't see how to fix undershoots. The "polygonize" tool works great, but it needs "closed polygons." If I could fix the undershoots, even by making them into overshoots, I'd be fine. I know ARC has "clean" and "Nodesnap" and tools that make what I want to do easy. The question is: can this be done with OpenJUMP or one of its plugins? If so, can you ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
