Can Gri draw maps?
Gri can draw maps, but it lacks builtin support for map projections. (A previous version had projections, but they were not working correctly and were removed.) Gri does not have builtin coastline files, either. Many good coastline files are on the web; see, for example, Rich Signell’s site http://crusty.er.usgs.gov/coast/getcoast.html or the USGS mapping site http://www.usgs.gov or the Global Self-consistent Hierarchical High-resolution Shoreline site http://www.ngdc.noaa.gov/mgg/shorelines/gshhs.
