Processing FIL Norway imagery
Jump to navigation
Jump to search
The biannual delivery of the FIL Norway ECW imagery dataset can be efficiently processed and converted to GeoPackage using the Python package filnorway_processor. This package will split the input according to a custom grid with 32768 x 32768 meters cells. The output is stored as GeoPackages with WEBP compression, and organized by county.
Dependencies
- GDAL >= 3.8.0 (with ECW driver)
The easiest way to get a Python environment where these dependencies are met, is to install the latest version of QGIS . Included is the OSGeo4W shell, where you can install and use the package.
Installation
The package is distributed as a Python wheel-file. Install using pip:
python -m pip install c:\path\filnorway_processor-1.0.6-py3-none-any.whl
