Note: depth maps are based off irl, not the in game charts

Save game compatbile? I started a new campaign and too much of the north sea is 20-50m. 50 is bad enough. 20m is suicidal for any target with an escort.

No it doesn't Twarda

Does this modification affect gaining achievements?

Hi, there seems to be missing data in game squares AC2-AC3 and AC5-AC6 are partially showing -1m see level.

I trust that youve done your Homework on this, Tofof. When testing I looked at my soundings at Scapa Flow which were shallow but you can maneuver across as your mod said that actual depth was 1m which would be impossible for me to go but it was. When I took the soundings I added my depth from the gauge to be reliable in the future. I do have the capacity to be an A**hole, its just when I think something is too good to be true it usually is.

Reaper, I considered removing the vanilla depth range, but I found that it actually made scanning for an area of a deeper or shallower depth very difficult. With the true depth changing with every pixel the cursor moves, the number is constantly flickering to new values. Real Navigation modifies the exact same text that this mod does, so it's no surprise that they conflict. One of the two mods would have to explicitly patch for when the other was present. Unfortunately, I have become extremely busy and will not have time to attempt such a change in the near future. It's probably better to ask Real Navigation to implement the same depth feature -- I'm just using the vanilla code to get sea floor depth, then simply reporting that instead of turning it into a range.

The way this mod works is directly reading the 3d geometry of the terrain height. In addition to the offset from keel depth, heavy seas can lift the boat as much as five meters above or below what's considered 'sea level', which can further confuse the reading you get from a sounding.

Unfortunately, the various depth gauge instruments (the papenburg meter, the two dials, and the UI dial) all display slightly different values for your own sub's depth, so there's not a good way to just pick a number to correct with. When you're surfaced, the ui gauge reads 0m but the actual instruments in the control room read 5-6 meters, which is how it would actually be. Periscope depth was more like 14 meters, not 8, historically, for the same reason.

Parrot, you're incorrect. Your soundings report the depth under keel, which subtracts at least 6 meters (it should only be 4.7 but in this game it's more) when you're surfaced, and of course more when you're at depth. It's rather rude for you to claim it's useless, even if it had a small offset, especially since it's just user error. I tested this extensively and it is correct. I considered correcting for the keel depth - I myself see 'actual: 47 meters' and will dive to 45 and bash my hull into the ground, because it's only safe to go to 41 - but if I did that then the vanilla game's ranges would conflict with my number. For example, for a seabed that's 22 m deep, if I subtracted the keel, it would end up reporting "20-50 m Actual: 16 m". And the various models of subs have different keel depths. The only sane choice was to just report the actual true seabed depth, which is what would've been charted anyway.

This is a great mod but however useless, I tested it against the soundings Ive labled on my map and its off. Its a great thought though rendered useless thanks to the Dev team who keeps the specs of their underwater topo secret and did bother to use the actual topography like you did Tofof. I had my doubts because of my experiance with the Scapa Flow run I did when I looked up the fortifications beforehand and sadly found the depths and half of the RN mines to be off.

Having the range still also interferes with your ability to read own ship cursor position around the map when using mods like real navigation. The text overlaps with making the cursor position unreadable.

Would it be possible to remove the depth range and just display the actual depth? The range seems obsolete if you've got the actual depth displayed on the next line already.

This is super helpful. thank you. now i knew clearly how deep it is under my sub. The default system always confused me. This is nice and easy. thanks

No new game needed, works with saves, great and useful tool.

new game needed?

so is the map in the game or does it just show the actual depth on the top right?

Wel done! Maybe the devs will be able to use actual bathymetry maps in game at one point.
