QGIS exercise
NOTE: NEW FILES GENERATED IN QGIS ARE TEMPORARY FILES AND NEED TO BE MADE PERMANENT BY EXPORTING AS LAYERS. TEMPORARY FILES WILL BE REMOVED WHEN YOU CLOSE QGIS
All steps
Step 1 – Download satellite image
Step 2 – Stack satellite bands to form RGB raster
Step 3 – Download boundary shape file
Step 4 – Clean up shape file
Step 5 – Generate NDVI
Step 6 – Clip NDVI
Step 7 – Reclassify
Step 8 – Landscape metrics

If QGIS tools are missing, go to – manage plugins – processing manager
If you can’t clip properly, try to check the create output alpha band in clip, or v.buffer.distance
