This tutorial demonstrates how to use QGIS to clip a raster layer to the shape of a polygon. This operation is also referred to as clip by mask, or extract by mask. QGIS makes clipping a layer to polygon very simple. If you're having trouble with no data values being displayed as zero or in black, this tutorial will show you how to fix it. Learn how to clip a raster by a mask layer, shapefile, or polygon in QGIS with this stepbystep tutorial. Discover the process of isolating specific areas of a raster image using different vector layers as masks. Uncover the powerful tools and techniques within QGIS for precise and efficient clipping of raster data.
