QGIS is an open source GIS program that provides unimaginable possibilities for viewing geographic data, analyzing geographic data and compiling maps. Other courses in our catalog have focused on working with vector data. QGIS can also be used to work with raster data, ie, elevation, land use / land cover and data converted from vector to raster. This course focuses on how to work with raster data in QGIS and how to turn that data into information. The course will feature Danish datasets as you learn to work with raster data to identify potential solar sites.
In the course you will be learning about:’
- * Preparing raster data
- – Loading raster data
- – Building a virtual raster layer
- – Reprojecting raster data
- – Clipping rasters
- – Resampling – e.g., from 0.4 m to 1 m
- – Symbolizing elevation data
- – Visualization settings
- – Based on extent
- – Briefly about other visualization methods
- – Calculating Slope and Aspect
- – Vector to raster conversion
- – Alignment raster data pixels if they do not match
- – Managing No Data values
- – Calculating Euclidean distance
- – GDAL tools
- * Examples of raster analysis:
- – Reclassification of rasters
- – Rescaling rasters
- – Introduction to the Raster calculator
- – Raster algebra
- – Site selection analysis – Identifying suitable sites
- – Slopes more than a specific threshold
- – Sunny slopes
- – No buildings
- – Proximity to roads
