There are a few things you need before starting to make a geofilter in Photoshop. The first is a map of your area, which you can find online or in a geographic information system (GIS). The second is an image of the terrain. This can be found online or in a GIS. The third is an image of someone or something that you want to geofilter onto the map. This can be found online or in a GIS. Finally, you will need to create a layer on your document called “geo.” This will contain the map and the terrain image.
