Ever needed to reuse the same raster extent & resolution across multiple QGIS tasks? My latest blog post shows how the Raster Layer Properties function can automatically grab all those details from a reference layer. A good way to make your workflows more consistent and error-proof. https://ecodiv.earth/post/rasterlayerproperties/ #QGIS #GIS #FOSS #Raster #OpenSource

Raster layer properties in QGIS – Ecodiv.earth

Use the Raster Layer Properties function in QGIS to extract and feed key layer properties into subsequent processing steps, eliminating repetitive manual inputs and ensuring consistent alignment.
