How to convert a continuous raster (from 0 to 1) to a discret raster (0 and 1)
My SDM give me a raster file with continuous value from 0 to 1. I want to convert this to a file with values 0 (for 0 to 0.5) and 1 (for 0.5 to 1). Can some one help ?

Hi,
It may vary depending on wheter you are using ArcGIS or QGIS, but in both platforms there is "raster calculator" .
Right-click on the layer, select raster calculator, then set the thresholds you want as min and max, and click apply. All values within your min & max thresholds will be set to 1, and the rest as 0.
