I am working with Habitat Suitability Modeling and I would like to use land cover data. Specifically, I am trying to obtain many raster layers, one for each class, where each pixel of the raster has a value that tells me the percentage (of the pixel area) that is covered by the land-use class I am currently considering. For example, considering deciduous forests, pixel values should range between 0 (for example in areas near the sea) from 100% (in mountainous areas). I would like to obtain a raster where a pixel can have a certain percentage of more than one class.
Do you know how can I do this in GIS environment (both QGIS and ArcGIS are fine)?
