### Here is a sample of *Mathematica* code used to visualize the data extracted from the CD-ROM. The program reads 16-bit raw data, computes the number of rows, then partitions the array, reversing the row order.

Needs["Utilities`BinaryFiles`"]
filename = "~test_out.bin" ;
temp = ReadListBinary[filename, Int16] ;
rows = Floor[Sqrt[Length[temp]]] ;
grid = Reverse[
Partition[
temp,
rows
]
] ;
ListPlot3D[grid, PlotRange -> {0, 5000}]

## The result:

This shows a (64-km)² sample from around the Washington, D.C., area.
