In this tutorial, we explain
In this tutorial, we explain everything you need to know to understand the concept of NDVI, which stands for Normalized Difference Vegetation Index, and see how we can compute NDVI by ourselves using freely available satellite data.
I’m going to walk you though this step-by step, all the way from understanding the meaning, and the concepts behind NDVI, to downloading the satellite that you need for this, and finally we are going to using a GIS tool like QGIS to do an actual computation of NDVI values and see how we can interpret our results.
