[gdal-dev] gdal get geolocation array in HDF5 dataset

Hi all, I would like to know I can I read with gdal the geolocation array stored inside an O3MSAF HDF5 data. With GDALGetMetadata( dataset, "" ); I get the list of metadata (es. Fill Value, Title, Unit but not the array with the latitude and longitude values), with GDALGetMetadata( dataset, "SUBDAT

[gdal-dev] GDAL 1.10.1 requirements

Hi all, I would like to know which versions of netcdf, hdf4, hdf5 libraries are supported by the new release of GDAL. I tried for instance 4.1.1 netcdf library but, after ./configure, I see "netcdf supported NO" . So I think that version is too old. With the latest versions (netcdf 4.3.0, hdf5 1.8

Re: [gdal-dev] gdal_grid: how to choose ellipse radius

Thanks Even, is the radius1 and radius2 unit in pixel? Because my grid size is: cloud coverage [km] / cloud resolution [km] so the pixel resolution of the grid is 1 pixel. Is this the right value to assign to radius1 and radius2? Should it be always an integer value? I think that setting radius1 an

[gdal-dev] gdal_grid: how to choose ellipse radius

Hi all, I am investigating Nearest neighbor algorithm of gdal_grid. The search ellipse is described by the three parameters: radius1, radius2, angle . My target is to get a regular grid as similar as possible at the original cloud of point, with the same values (no interpolation, so I choose the N

Hi all, I am going to use gdalwarp to resample a 800x800 wgs84 image but I did not understand how to set output file resolution: gdalwarp description page says to use the option -tr , but what does it mean with "in target georeferenced units"? This is my input image: Size is 800, 800 Coordinate Sy
