[gdal-dev] Is it possible to write custom CRS WKTs within a GeoTiff?

2025-01-08 Thread Scott Henderson via gdal-dev
Hello gdal-dev, I’ve looked around for an answer to this one to no avail and would appreciate any insight from those more familiar with the GeoTiff format. I’d like to be able to store a custom WKT *inside GeoTiff metadata* rather than in an external PAM file. I’ve seen some solutions to add cu

Thanks for the speedy reply Even! I had not considered alternative tile layouts. I did open an issue here if others want to chime in: https://github.com/opengeospatial/CloudOptimizedGeoTIFF/issues/37 Scott > On 7. Jan 2025, at 17:23, Even Rouault wrote: > > !---

[gdal-dev] Stacks versus mosaics with GTI Driver

2024-11-26 Thread Scott Henderson via gdal-dev
Hello all, I have a question on scope of the GTI driver, which I think provides a really nice capability for a lightweight single file raster catalog! One very common pattern I use and often see others using is `gdalbuildvrt -separate stack.vrt *.tif` for approximately-coincident satellite im

[gdal-dev] optimal vsicurl settings for merging range requests

2018-12-18 Thread Scott Henderson
There are many environment variables for optimizing access to remote geotiffs via GDAL’s /vsicurl/ interface. I’ve noticed that directly downloading a file via curl can be much faster (~4x) than pulling the entire file via gdal_translate or gdalmanage, and I think this is due to 1 GET request ve
