Hey,
Etienne Tourigny-3 wrote > I use a similar command, without the -a_ullr argument And does it then capture the correct corner coordinates? If i run your command it does assign the sinusoidal projection, but takes the pixel coordinates (eg 0-2048) as the corner coordinates instead of the sinusoidal ones. @Laura, Indeed we are talking about different products, sorry for the confusion. You mentioned in your first email the products MYD14.A2 and MOD14.A2. I thought you meant the "MYD14 A2" product, but you attached a "MYD14" product, which is different. Its obvious where the confusion comes from. :) These are all the fire products: MYD14 Aqua Thermal Anomalies & Fire Swath 1000m 5 min MOD14A2 Terra Thermal Anomalies & Fire Tile 1000m 8 day MYD14A2 Aqua Thermal Anomalies & Fire Tile 1000m 8 day MOD14A1 Terra Thermal Anomalies & Fire Tile 1000m Daily MYD14A1 Aqua Thermal Anomalies & Fire Tile 1000m Daily MOD14 Terra Thermal Anomalies & Fire Swath 1000m 5 min The "MOD14" & "MYD14" products are indeed swath, and should be used together with the MOD03 with the same timestamp. I think the best way to process them is by using "MRT Swath" which you can download at: https://lpdaac.usgs.gov/tools MRT Swath is way beyond the scope of this mailing list, but feel free to send me a direct email about it if you have questions. I have used Pyresample as an alternative which works very well, but requires the use of Python: http://code.google.com/p/pyresample/ To end with an actual GDAL related solution, there is an option to warp an image using gdalwarp and so-called "geolocation arrays". I can get it to work with the MODIS swaths, but i dont like the results at all. It is previously discussed at: http://osgeo-org.1560.x6.nabble.com/gdal-dev-reproject-python-numpy-binary-swath-lat-lon-td4978609.html The MODIS swath products arent equally gridded and still contain what is called the 'bow-tie' effect. (overlapping scans at high zenith angles). I dont know if the GDAL geoloc option is supposed to handle this properly. The image a posted earlier in the thread mentioned above clearly shows artifacts which i cannot explain or resolve.
