ReadNTF
DESCRIPTION
This module reads data in from a digital terrain data file in
National Transfer Format (NTF) and outputs it as a uniform
2D lattice.
INPUTS
WIDGETS
Port: Input File
Type: File Browser
Input file. The module checks to see if it can open it,
and makes some attempt to check the format to see if
really is an NTF file.
OUTPUTS
Port: Lattice
Type: Lattice
Constraints: 2-D.
1-vector.
short.
uniform.
Output lattice.
PROBLEMS
This module assumes that all NTF files contain dtms that
are dimensioned 401 by 401 with a spacing of 50m between
each row and each column. It doesn't check this, but
it should, since this information is in the header of
the NTF file.
