Re: [gdal-dev] Creating Cloud Optimized GeoTIFFs

Hi Even, I have seen pretty much everywhere that COG's are created in 3 steps: 1. compress and tile the image $ gdal_translate -co TILED=YES -co COMPRESS=DEFLATE in.tif tmp.tif 2. add overviews $ gdaladdo -r average 2 4 8 16 tmp.tif 3. reorder overviews $ gdal_translate -co TILED=YES -co COM

Re: [gdal-dev] Creating Cloud Optimized GeoTIFFs

(working from pretty close to head...) A follow up question on how to create cogeo files... I appear to need to do additional work to set BLOCK_OFFSET_?_?. How do I go about this? I'm trying to create a cogeo without gdal_translate in java by using create and createcopy like this: https://gist

Re: [gdal-dev] Creating Cloud Optimized GeoTIFFs

Thanks Even for the feedback. There have be a few offline discussions going on and Even added some notes to the document on Trac: https://trac.osgeo.org/gdal/wiki/CloudOptimizedGeoTIFF?action=diff&version=11

Re: [gdal-dev] Creating Cloud Optimized GeoTIFFs

Hi Even, I have some follow up questions on Cloud Optimized GeoTIFFs: * Is there a preferred/better INTERLEAVE if there is more than one band? * Is there a preferred tile blocksize? You have 512 in your examples. Are there any major trade offs between using 128, 256, 512, or 1024 for x and y bl

[gdal-dev] Creating Cloud Optimized GeoTIFFs

Hi, I ran into something confusing when using gdal-2.2.0 to generate Cloud Optimized GeoTIFFs following the instructions at: https://trac.osgeo.org/gdal/wiki/CloudOptimizedGeoTIFF Here's what I did: 1. Fetch an image: env CPL_VSIL_CURL_ALLOWED_EXTENSIONS=tif GDAL_DISABLE_READDIR_ON_OPEN=YES VSI_
