Consider coordinate projection for Alaska NSHM
Currently, lon-lat coordinates are effectively treated as cartesian coordinates, with gridded rates (always?) scaled by latitude (e.g. #50). This may be appropriate for CONUS and HI, but may cause issues in Alaska where lon-lat grids scale much more strongly with latitude.
Maps show 0.1 degree grid vs. polygon in cartesian, mercator, and Albers-conic projections. Some grid points appear to be outside of the polygon boundary except for the cartesian map. This effect is exaggerated in Alaska. Dashed red lines follow great circle, blue lines are straight lines. Red dots are inside polygon, black are outside. Click maps for larger view.
