Uncover the coordinate reference system (CRS), its coordinate system and datum, and compare geographic and projected systems to enable accurate overlay of spatial data.

Install the QGIS plugin, add Google satellite and Google base map layers, identify a water body, and compare its position to the maps to verify georeferencing.

In QGIS mastery, learn to mosaic two topo sheets using the processing toolbox for geospatial analysis, select the topo sheets as input layers, and merge them into a single layer.

Master how to analyze a digital elevation model in QGIS by viewing elevation statistics and generating slope, terrain ruggedness index, topographic position index, and roughness.

Explore river hydrology by examining river flow, channels, and networks and watersheds to understand how water moves, shapes landscapes, and informs flood risk and water resource management.

Reproject the dm, apply the Wang and Li tool, use Strahler order to set a fifth-order threshold, and generate the river network by enabling channels.

Learn to extract real river lengths with field calculator, compute total and mean lengths, and derive morphometric parameters like drainage density and bifurcation ratio from a river network.

Create hillshade maps in QGIS from a digital elevation model to simulate light and shadow, revealing terrain with depth. Apply visualization techniques for urban planning and environmental studies.
