Re: [gdal-dev] GDAL Cubic Interpolation

2017-10-11 Thread Harvey Berger
To follow-up on my latest email, I confirmed that GDAL is interpreting the pixels in the augmented image file from Octave as uint16 rather than int16, and this results in incorrect elevation values after cubic interpolation and subsampling (e.g., a pixel elevation of -28 m is misinterpreted as 65,5

Thanks Joaquim and Even, Per my email I augmented the original GLOBE image and created a properly referenced image using gdal_translate as follows: I did an imread from QGIS/GDAL into Octave, added the appropriate 24 rows and columns on each side, and did an imwrite back to QGIS/GDAL to continue p

[gdal-dev] Removing the *raster* OGDI driver ?

2017-10-11 Thread Even Rouault
Hi, I propose to remove the raster OGDI driver from trunk (the vector OGDI driver is still useful for VMAP/VPF/DCW) There should be no reason to use it anymore since GDAL supports out of the box (and probably in a more efficient way) all the raster formats the OGDI bridge offers: ADRG, DTED a
