Hi There,
I am a GIS guy. I see what you are trying to accomplish. I can generate this software pretty quickly. I have ready libraries for binary file reading, subfolder scanning, etc. I will provide you with a GUI where you can select the top directory and the app will scan all the folders to find files and process them.
I am planning to develop it in C#.
One question about the format. You wrote "LongSeg = Next 5 digits is the longitude segment" but in the file name it is 012444 : 6 digits. I think this is just a simple mistake or am I missing something?
So, the output file for a grid file will contain 1000 x 1000 = 1 million lines in the given format. In the output format you specified "backscatter_field" which corresponds to "byte mag" field, I guess.
I am free now. If you award me the project, I can work all the night and come up with a surprise tomorrow. I want to rock back in this platform - I had been away for a while, but now I have a team behind me. For your project, I will work on my own, though.
I will have a couple of more questions about the final output format if you award the project.
Waiting for the "Go!".
Regards.
