Re: [gdal-dev] How proceed with GDAL GeoTIFF files with multiply subdataset

Hi now I am using following c++ commands to read pages from multisubdatasets Geotiff file :    dataset = static_cast(GDALOpen(TiffFullName.c_str(), GA_ReadOnly));    if (dataset == NULL) {        std::cout << "Failed to open subdataset nr = " << subsets << " Read command =  "

The file is indeed fine and was recognized in earlier GDAL versions (<= 3.4). Bug fixed per https://github.com/OSGeo/gdal/pull/7382 Le 08/03/2023 à 14:22, Micha Silver a écrit : Inline... On 08/03/2023 14:33, Even Rouault wrote: Ah, the issue here is that the GeoTIFF keys in the .tif part

Re: [gdal-dev] How proceed with GDAL GeoTIFF files with multiply subdataset

Hi, Do you know that your source file is a multipage TIFF? Could you share a small test file? There is python test for reading a multipage TIFF at https://github.com/OSGeo/gdal/blob/master/autotest/gcore/tiff_read.py#L582, please have a look. -Jukka Rahkonen- Lähettäjä: gdal-dev Puolesta Rai

[gdal-dev] How proceed with GDAL GeoTIFF files with multiply subdataset

Hi I found from documentation following about subdataset: Subdatasets Multi-page TIFF files are exposed as subdatasets. On opening, a subdataset name is GTIFF_DIR:{index}:filename.tif, where {index} starts at 1. I am using foll

Re: [gdal-dev] ERROR 1: No inverse operation

Ah, the issue here is that the GeoTIFF keys in the .tif partially define the projection (or possibly the .tif.aux.xml contain this invalid WKT). But METHOD["unnamed"] means that the projection method is unknown, so it is logical that GDAL/PROJ can't compute geographic coordinates from projected

Re: [gdal-dev] ERROR 1: No inverse operation

Hi Even: Here's the full gdalinfo, with the reported CRS: gdalinfo HiBar_21022022_A1.tif Driver: GTiff/GeoTIFF Files: HiBar_21022022_A1.tif   HiBar_21022022_A1.tif.aux.xml

Re: [gdal-dev] ERROR 1: No inverse operation

gdalinfo is usually showing the coordinates of the corners and center in the CRS of the GeoTIFF, and also in WGS84 in degrees as conversion of the previous. Looks like your CRS does not support such conversion. If you paste the full output of gdalinfo there should be some clues about the CRS used.

Re: [gdal-dev] ERROR 1: No inverse operation

Micha, which CRS is reported and which PROJ version do you use ? It is presumably one projection method for which PROJ only implements the forward conversion, that is from geographic to projected coordinates, but not the reverse way Even Le 08/03/2023 à 09:37, Micha Silver a écrit : I
