I have downloaded a 7.5 min DEM . Now while I am trying to mosaic them it gives me an error saying "Input and target dataset should have the same number of bands" . How can I figure out the number of bands for the input dataset.
The DEM I have downloaded is for Montara Mountain from the following site http://bard.wr.usgs.gov/getDEMSMap.html
I am using ArcGIS 10.0 to generate a elevation data. So basically using Mosaic to new Raster (Input are two DEMs). Then this output is projected and then using the meters conversion I want to get the elevation data. I tried to get the properties in ArcCatlog but cannot view it. And this DEM data cannot be added in ArcGIS .It throws an error invalid raster dataset.Failed to create a raster layer.

DEMs have 1 band which hold elevation values. For comparison, a color image has three bands (Red, Green, Blue). You can check information about any raster dataset by:
Other particularly useful information located here include pixel depth, cell size, coordinate system, and format. Make sure to set the bands to "1" in the Mosaic to New Raster tool.
