About this 3D model
Here are improved versions of relief maps for Kauai and Niihau. See thing:106099 for the earlier version. There is also a high resolution map of a portion of the north coast of Kauai. The three maps are: Kauai_step.stl 140 x 190 points at 12 arc second intervals Niihau_step.stl 200 x 200 points at 6 arc second intervals Kauai_coast.stl 175 x 175 points at 1 arc second intervals Data for the first two maps came from NOAA http://www.ngdc.noaa.gov/mgg/dem/demportal.html Data for the high resolution map was from the USGS National Map. http://viewer.nationalmap.gov/viewer/ The programs used were described in things 106099 and 116103.
