I'm trying to clip a DSM mosaic I've made with a shapefile on ArcMap 10.7 but when I use extract by mask tool, the output is just empty and when I change the no data colour to red, all I get is a red square. The cell value ranges are -3.4E+38 --- +3.4E+38. The strange thing is that the corresponding DTM clips absolutely fine. Both the coordinate systems are the same (British National Grid).

I'm pretty new to GIS, as you may be able to tell, does anyone have any idea of what I am doing wrong?

  • Have you actually computed statistics on the raster, or are you using the default range of the IEEE floating-point value? – Vince Feb 6 at 19:54
