About this 3D model

Here are relief maps of Martinique and some of the Caribbees. Data was taken from GMTED2010, a USGS data set available from the earth explorer web site. http://earthexplorer.usgs.gov/ GMTED2010 is a global elevation data set in geotiff format. A 7.5 arc-second resolution file, 10n090w_20101117_gmted_mea075.tif, was downloaded and converted to "raw" format with Adobe Photoshop. The raw format file contains 14400 rows and 9600 columns of two byte signed integers. A fortran program similar to those in things 118327 and 121275 was used to treat the raw file. Stl files are: st_kitts_nevis.stl 210 x 210 points at 7.5 arc-seconds guadaloupe.stl 240 x 200 points at 15 arc-seconds dominica.stl 170 x 240 points at 7.5 arc-seconds martinique.stl 250 x 260 points at 7.5 arc-seconds st_lucia.stl 155 x 220 points at 7.5 arc-seconds st_vincent.stl 150 x 300 points at 7.5 arc-seconds The fortran program that created the openSCAD polyhedron commands is included.
