GDAL

Solved: QGIS 3.20 Python Console shows an error when running Clip Vector by Extent tool

ERROR 1: Attempt to write non-multipoint (POINT) geometry to multipoint shapefile. ERROR 1: Unable to write feature 0 from layer points_layer. ERROR 1: Terminating translation prematurely after failed translation of layer points_layer (use -skipfailures to skip errors)

Solved: new version rasterio 1.0+ won’t let me use GDAL transforms

This week, I am discussing an error which used to be a warning on the old rasterio - and I ignored it. Lesson learned! I was doing my usual savings of GeoTIFF rasters in an updated python environment (with rasterio 1.2.6) when I saw this error:

Solved: GDAL accuses no free disk space when there is plenty

[SOLVED] ERROR 3: Free disk space available is 85802630536 bytes, whereas 730874237760027488 are at least necessary. You can disable this check by defining the CHECK_DISK_FREE_SPACE configuration option to FALSE.

How and when to use QGIS 3 tools “Warp (reproject)”, “Clip raster by extent” and “Clip raster by mask layer”

Today, I am discussing different ways of cutting (clipping) a raster in QGIS and what they do. Especially, I am comparing QGIS GDAL tools “Clip raster by mask layer”, “Clip raster by extent” and “Warp (reproject)” in what are they used for, and what exactly do they do to the original raster data.

Batch processing – automatizing the use of GDAL and SAGA GIS tools using Bash Shell scripts

One of the simplest yet most tricky ways of doing batch processing is by using Bash scripts. Bash is a type of Shell Script, which means it runs directly on a user interface that accesses the services of an operating system.
