Need help with files related to map - .lotpack .lotheader .bin

[Airr]

Hello everyone.

I am interested in ".lotheader" ".lotpack" and ".bin" files that generates when you create a new map. There is no ability to look what inside this files, because it has "data" format and not everything can be viewed through normal editors. So my questions is there any place where can I read how to create this files? What is this file structure etc.
I am thinking of create a mod\tool, and I need to know how to correctly create this files so game can read it and replace game cell with information that I put into this files (for example)
