This file contains information on the activity of aliens in both countries and regions. The same format is used for XCOM.DAT only it obviously applies to XCOM activity in the area.
Structure
The format is rather tedious and the best line width is 124 bytes, which will cover an entire month of both Countries and Regions. There are a total of 12 months stored in this file. Each value is stored in 4 bytes in the usual low then high manner. It is presumed that they are signed and will go negative after FF FF FF 7F (0x7FFFFFFF in normal notation), but this has not been tested, nor should it be possible in the game normally.
The first record contains this month's information. The second last month's and so on. Each UFO adds one to the appropriate territory it is over on each 30 minute update period, so a score of 100 would indicate UFOs spent 50 hours (roughly) over that territory in the month. If it is over a specific country, it will also add one to that counter each 30 minutes, as well as incrementing the territory.
For XCOM a different way of ranking activity is used.
These offsets were completely ripped from Hatfarm's website, with some rearrangement to aid look-up (hopefully)
