You can save the updated vector layer as a new file by right-clicking the layer and selecting “Export” > “Save Features As…” and choosing your desired format (e.g., shapefile or GeoJSON). Now, you’ve successfully extracted raster values into polygon attributes. Check the results: Open the attribute table of your polygon layer by right-clicking the layer in the Layers panel and selecting “Open Attribute Table.” You should see new columns with the raster-derived statistics.This will calculate the specified statistics for each polygon using the raster values and add them as new attributes in the polygon layer. Run Zonal Statistics: Click “Run” to start the Zonal Statistics process.Configure Zonal Statistics parameters: In the Zonal Statistics dialog, select your vector layer (polygon) as the “Input vector layer” and your raster layer as the “Raster layer.” Choose the attribute prefix (e.g., “raster_”) and select the statistics you want to calculate (e.g., “Mean”).Compute Zonal Statistics: click on “Raster” > “Zonal Statistics” > “Zonal statistics” to open the Zonal Statistics dialog.To do this, click on “Layer” > “Add Layer” > “Add Raster Layer” for raster data and “Layer” > “Add Layer” > “Add Vector Layer” for vector data. Load raster and vector data: Open QGIS and import both your raster and vector data ( shapefile or GeoJSON) into the project.Install QGIS: Download and install QGIS from the official website.In this example, I’ll provide steps for using QGIS, which is an open-source GIS software: Want to stay ahead of the geospatial curve? Listen to our podcast! To extract raster values into polygon attributes, you can use the GIS software of your choice, such as QGIS or ArcGIS.
