Subject: | RE: [mget-help] Binary to Geotif file format |
Date: | Mon, 6 Feb 2012 10:38:56 -0500 |
Dear Mukesh, Thanks for your interest in MGET. The MGET tool called Convert Binary Raster to ArcGIS Raster can probably convert that data. Unfortunately there are some complications. The documentation for that dataset does not specify the parameters that are needed for conversion, such as how many rows and columns there are, what data type is used, and what projection is used. I am fairly sure it is using a global EASE grid, like many NSIDC products. At 25 km resolution, that grid should have 1383 columns and 586 rows, or 810438 cells total. But the files are not that large; most of them are only 419840 bytes. My guess is that the files do use the global EASE grid, but they do not actually have global extent. They probably do not cover +/- 90 latitude. The Matlab code here appears to have the answer. Unfortunately, to figure out what extent is actually used, we must actually look inside the files globland_lat and globland_lon. This is something I can do, but I cannot do it right now, as I must depart for a cross-country trip in a few hours. Are you capable of doing this? If not, I might be able to help you later this week; probably Wednesday or Thursday. Best regards, Jason From: Mukesh Singh Boori [mailto:] Dear Sir/Madam |
