Re: [gdal-dev] Need to resample climate data to very fine resolution

2015-07-13 Thread Ivan Lucena
Bailey, It seems like you don't need geometric transformation of your images. We can see that your input is called reprojected. You just need to re-scale it, interpolating/filling it up with pixels values based on cubic method. You can do that with gdal_translate -tr or -outsize parameters.

Do you have any idea on how will I batch process gdalwarp these HDF5 files? -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Getting-warning-when-opening-NetCDF-file-using-gdal-tp5213484p5215504.html Sent from the GDAL - Dev mailing list archive at Nabble.com. _

[gdal-dev] Need to resample climate data to very fine resolution

2015-07-13 Thread Morrison, Bailey Danielle
Hello, I am having issues using gdalwarp to resample climate data to a finer resolution. Each climate raster has been clipped to the extent of Alaska, and contain >300 layers (1 for every month from 1979-2010). The current resolution of the rasters is >1000 km and they need to be resample to ar

Ahem, I think this is the original tutorial intended by Trent: https://trac.osgeo.org/gdal/wiki/UserDocs/RasterProcTutorial See lower down under "Virtual files". (The other page was specific to another project, now defunct - though it did source from this original GDAL tutorial) Cheers, Mike.

Jesse, The problem with warping is that you might incur resampling. Here is an older thread, no longer exists beside in the wayback machine, which explains how you can swap sides using pixel tricks in a VRT header (pointing to your original data). https://web.archive.org/web/20130618003511/http:

Hi again, I'm interested in trying to use the "Script-level Access via GDAL" guidance on the NASA "GIBS API for Developers" page: https://wiki.earthdata.nasa.gov/display/GIBS/GIBS+API+for+Developers The layer I'm interested in is "ASTER_GDEM_Color_Index" which is elevation data. The site contai

Hi! I'm processing some global GRIB2/netCDF data which have East-West coordinates of 0-360 degrees. I need to have the output data on typical -180, 180 range to process them later with some other data. When I reproject them to WGS84 and convert to GeoTiff, the output is still 0-360. I found that
