Meandering rivers paint stunning pathways across the landscape. Using lidar (light detection and ranging), we can see the history and beauty of a river’s movements across their floodplain. In Relative Elevation Models (REMs), the elevation is normalized to the surface of the water so that all the features of the floodplain are highlighted. The resulting REM images are stunning works of art!
I created these REM images following this tutorial by Daniel Coe on how to create REM images in QGIS. All lidar data was accessed from OpenTopography.
