QGIS Tutorial – 3D Map view in QGIS 3.4.6



Hi GIS learners here in this series of QGIS Tutorial we learn 3D Map view in QGIS 3.4.6. For 3D view you need DEM – Digital Elevation Model. If DEM alien to you then first understand what is DEM.

What is DEM?

Digital Elevation Model abbreviated as DEM is a 3D view or raster representation of terrain and its is in grid form. Each cell represents a value and each cell or pixel have their single attribute. We can define it as an ordered array of numbers that represent the spatial distribution of terrain attributes. The quality of DEM is a measure of how accurate elevation is at each pixel level and how accurately is the morphology presented.
