7.9.3. Clipping to study area extent

The resulting raster g100_06_ch1903.tif still covers all Europe, so we will now clip it to the extent of our polygon layer commune_boundary_FR.shp.

  1. Open Raster.
  2. Select Extraction.
  3. Open Clipper.
  4. Select g100_06_ch1903.tif as Input file.
  5. Choose CLC06_Fribourg.tif as Output file name.
  6. Choose Extent within the Clipping mode and enter the minimum and maximum values for x and y according to Fig. 110 (xMin: 564835, yMin:168930, xMax: 593200, yMax: 196915). To look up these values, double-click the layer commune_boundary_FR.shp in the Map Legend > Layer Properties >  Metadata. In GIS, minimum and maximum x and y values can also be obtained manually by hovering over a location on the map and reading the x and y values from the bottom right-hand corner of the screen (Fig. 110).
  7. Activate the checkbox Load into canvas when finished.
  8. Click OK to start the clipping process.
  9. After the clipping has finished, remove the big layer g100_06_ch1903.tif from the Map Legend.
  10. The result should then look similar to Fig. 111.
