Dear gdal-dev I am currently working with some burnt area (GeoTIFF) data from the University of Maryland (http://modis-fire.umd.edu/Burned_Area_Products.html). I have been attempting to subset this data to my study area. Unfortunately when I subset the GeoTIFF the output is offset in a south easterly direction by approximately 200m. Below is my command.
gdalwarp -s_srs EPSG:54001 -t_srs EPSG:4326 MCD45monthly.A2009244.Win13.051.ba_qa.tif test.tif The data are in Plate-Caree projection (lat / lon not meters) and I have been struggling to figure out how to change this as I believe that this is the source of my problems. I have tried various approaches using both EPSG:32662 and EPSG:54001. As well as some suggested on the mailing list. http://osgeo-org.1560.x6.nabble.com/Does-GDAL-handle-rotated-spheres-td3763008.html Unfortunately I am unable to solve the offset problem. I am using the following version of gdal on an Ubuntu 12.04 GDAL 1.9.1, released 2012/05 Any help or advice would be much appreciated.
