Thanks guys. I hope you find the information useful. I was up until 3am PST finishing the post so I may have been a little punch drunk and suffering from lack of sleep, besides seeing things, hehe.
Just play around with my instructions if you have a system capable to handle the raw map files and you can do almost anything. Just experiment.

Yes, you can add what you like. Later on I was figuring to use that one Satellite mod that showed you all the shipping traffic so I could create general shipping lane markers. I added the red color to the Color Table in hopes of using it to mark the general location of minefields and nets. I say general because if you zoom in on either map (4320_2160.raw & 21600_10800.raw) file, you won't get that detailed of a close-up. I believe the tile files in the Map2 folder are for the extreme zoom-in views but I haven't figured out how to open or modify them yet.

Yeah I know. Just a crappy jpeg I spit out to give you some idea of what I've been up to. Same reason though that I'm not putting my map up for download yet. Still experimenting. All of the names used on the map I created came out of a huge sized encylopaedia brittannica world atlas from 1956 that my dad had, so if some of the names are not correct for the period,WWII, then that's my fault.

I would imagine you could add the numbers on the map to indicate the depth for the area. I don't think I would add too many because it might start crowding the view, but it is something worth looking into. My only concern would be that if you used the depth data from say the AOD OKM chart, how accurate is the depth portrayed in SH3 compared to a know depth chart? Probably a lot of trial and error to get it reasonably right.
L8r guys.
I'm glad some of you can use this info.
