Hi All, Before trying to reinvent the wheel, I was wondering if the mapproj or any other library had code to take lambert coordinates (along with the parameters used to generate them) and convert them to lat long. I have grid data in lambert coords, and want to generate the long/lat grid corners from them. I noticed mapproj goes long/lat -> projection, but couldn't find anything to go the other way. I was going to use the reference in wolfram mathworld to do the inverse transform, if anybody has any issues with their version.
http://mathworld.wolfram.com/LambertConformalConicProjection.html Basically, I want to keep the data stored as grids, but every now and then I want to create distance matrices or plot them (which I currently do with an irregular grid class I made up), but don't want to store polygons all the time when I can just store the basic grid. All comments welcome. Thanks, Blair _______________________________________________ R-sig-Geo mailing list [email protected] https://stat.ethz.ch/mailman/listinfo/r-sig-geo
