I am using ArcMap (10.4.1) to work on a landcover dataset. The file format of the raster layer is "tif". However, for some reason, many of the functions in Arcmap are not available - for example, all selection tools are grayed out (see screenshot) and when I want to use the "Clip" tool I cannot select my layer as an input feature. I assume it has something to do with the format of the raster layer, which is why I include a screenshot of the layer properties as well. I have searched google for almost an hour but not found a solution..
You cant select a raster so if all layers are rasters the selection Tools will be greyed out.
Also I Think the clip tool you want is located in Data Management Tools - Raster - Raster Processing - Clip. I belive there are Three Tools called Clip :)
