Dam It Course (Conservation/Agriculture)
In this course you will learn how to estimate a number of quantities for a potential dam/reservoir site in 3.28.14-Firenze. This course perfect for those who would like to accurately estimate the flood plain, dam wall length, spill way height, dam wall facade area and the volume of a potential irrigation dam, water reservoir or slime dam using UAV data, photogrammetry outputs and GIS. I have left in some of the glitches so that you can see how open source is not always optimised when it is updated or alternative versions of the software are used, this will ensure that it does not come as a surprise when using updated or older/ newer versions of the software. You will need to download and install QGIS from the Software/ Hardware Requirements page for this course. In this course you will learn:
