I have developed a primitive python/Qt/Silx program to edit hgt files. It requires
Python
Qt
Silx http://www.silx.org
Here is the primitive code.

My initial goals would be to eliminate the need for Silx toolkit, display the decimal fraction of degrees instead of 0-1200, then a "file open" and "file save" function.
Any thoughts?
