how to clip a DEM with/to a shapefile?

Question

Hello,

I created a DEM by taking a shapefile of points, and processing it in the Spatial Analyst IDW interpolation tool. The result is a raster image with 10 raster bands (which, however, if I drag from the catalog into the layer, is black and white). I need to take this raster image, which is in the shape of a square, and clip it with a shapefile, that is the boundary of a forest. When I try to use the clip function from the geoprocessing menu, it doesn't allow me to drag in the raster image. I tried several other tools, like extracting by masking, and it doesn't give me what I need. I need the square raster image to be the shape of my shapefile.

How do I do this?

Thank you

Hi,

From a 'most recent data format' perspective you should use your DEM Raster as a mosaic dataset (of type elevation, which will be useful in other ways like stretching, ... see documentation). Your boundary shaepfile can then be loaded into the mosaic as just that - the boundary - and you are all set for analysis

You can use Extract by Mask tool, it's here clip DEM with a polygon shapefile  clip DEM by polygon in ArcGIS - YouTube
