Thank you for your video I have a question, I would to classify wetlands according to water index and NDVI index, how can I make a condition for raster e,g if water index >1 this cell is water, and if water index < 1 and NDVI > 0.5 is high vegetation, another condition e.g if water index
Sadiq Almalki In gis, you can use conditional statements in raster calculator. However, the syntax of these kind of statements in arcgis and qgis are different. In arcgis, there's a statement called 'con' and others and in qgis, it's very simple. In qgis, your problem can be simplified as: ("water index">1)*1 +(("water index"
