Tool to generate netCDF file from a Tiff file. The contents of the netCDF will be determined by the variable in the Tiff file. The array information such as the coordinates, projection (if any) will be copied from the Tiff file.
Example usage: Convert slope Tiff file to a 2D netCDF with slope as the variable
Input: Tiff file
Input: Variable name
Output: A 2D netCDF with the variable values from the Tiff file

This tool will produce an aspect file from DEM
Input: Terrain DEM file; Format: Tiff
Output: Terrain Slope file: Format: Tiff

This tools calculates the slope in the steepest direction from each grid cell in a DEM.
Input: A DEM file; Format: Tiff
Output: A slope file: Format: Tiff

This tool takes a National Elevation Dataset (NED) DEM and extracts a the subset of it.
Input: NED DEM; Format: Tiff file
Input: The North, South, East and West Boundaries of the subset; Format: Float point number
Output: Subset DEM; Format: Tiff file
