Dear All, A question from a very beginner with maps and geographic data. I have a map with many (too many) vertices which I would like to use interactively over a web page. What I need is to simplify that map, make it <similar> to the original one but discarding 90% of the current information. I read that is possible using QGIS (which I have installed), but I wonder if it would be possible in R. I would gladly use an R function instead of learning how to use QGIS. Thanks in advance, Adrian
Not an R method but way easy, http://www.mapshaper.org/ A quick search shows several R packages that also have the Douglas-Peucker algorithm. Look at 'shapefiles' or 'cshapes' packages Enjoy, Alex
