[gdal-dev] In GDAL Warp What WM Should I Choose

2021-08-25 Thread Thet Lin Thu
I am trying to stitch a global elevation raster dataset made of 14,000 files into 1 single 120GB file. I already have the VRT generated and have tried applying both gdal warp and gdal translate on it with varying results in speed. Although I am not warping anything (same projection for the input a

[gdal-dev] Retiring osgeo/gdal:alpine-ultra-small Docker image

2021-08-25 Thread Even Rouault
Hi, I'm considering retiring the osgeo/gdal:alpine-ultra-small Docker image. It's size difference with the osgeo/gdal:alpine-small one is small (50 MB vs 59 MB), and with arm64 images being now generated, the cross-compilation time for it becomes a bit painful. Any opposition to that? Even

Hi Even, Thanks for looking into it. I suspected it might be something we have to live with, but thanks for confirming. I can get round the problem by creating a dummy feature using the input layer extent then deleting it later, but it's an ugly workaround. Weirdly, once you've hit the error,

Jon, I believe this is a bug/feature of the (closed source) FileGDB SDK itself when it . Not sure we can do much about that. Or according to some mysterious parts of the documentation of the SDK perhaps we could offer to the user, as layer creation options, the possibility to specify the valu

Hello all, I'm using GDAL 3.2.1 on Python 3.6.8 and am looking for more information on FileGDB spatial indexes. I have a File GDB layer containing some features and where the geometry is below a certain size, I'm trying to replace it with a larger geometry. However, I'm getting the error Runtim
