Thanks for reply. I think I have too many shapefiles to use a web interface like that.
I did find gpsbabel, which seems to be the Linux command line program I am looking for. However my shapefiles are polygons, and I can convert them to KML with ogr2ogr and they are still polygons, but whenever I do anything with gpsbabel and it's point reduction algorithms, I loose the polygons. Obviously I have a lot to learn, and hope this makes sense. So I still dont have a good way to reduce the size of these Polygon shapefiles, tom On May 8, 12:04 pm, Brian P <[email protected]> wrote: > I'm wondering, do you need something like > this?http://facstaff.unca.edu/mcmcclur/GoogleMaps/EncodePolyline/encodeFor... > > It generates encoded polygons/polylines, and there's a setting called > "verySmall" that adjusts the appearance of points at various zoom > levels.
