Ta. There was a map somewhere that showed all of the russian fortifications in Ukraine, I think OS referred to it further up. I've searched the thread and can't see the link anywhere though.
I think the map you're looking for was embedded in a Twitter thread. I also think this might be the caboodle...

Ja, that's the map. It's interactive too, so if you zoom in and click on the red dots denoting a fortification it provides a link to the Sentinel-2 satellite imagery. No way I'm looking through it all, but some of those red dots are probably militarily useless, for example as a test before I posted this I checked the satellite imagery for the fortifications circling the town of Bilmak, which would be a useful place to take if Ukraine attacked in the Mariupol or Berdyansk direction (the Flockwitt plan), and is in the 2nd/3rd layer of Russia's defences from the point of contact. The satellite images show the northern defences of Bilmak are probably useless, long straight trenches. On the righthand side of the Sentinel-2 page there's toolbar with a measuring tool, using that each section of trench is 500m or so long and straight. In the top right toolbar in "layers", there's a contours option, the terrain is just about flat an armoured vehicle is going through all that terrain no problem if the ground is dry.
If you zoom in to maximum resolution and using the measuring tool on the pixels, it's possible the straight trench lines are actually 10m-20m saw tooth lines (similar to the videos of Ukrainians clearing shallow trench lines that zig-zag somewhat but are also straight somewhat). But there's been photos from ground level of perfectly straight Russian trenches, so on the other hand maybe it's just straight.
I would be shocked if NATO/Ukraine haven't gone through all this multiple times, using much better satellite imagery than what's commercially available, and using drone fly over footage too. Those red dots should be taken as a maximum representation, a lot of the stuff away from the frontline (and beware, I haven't gone through every single red dot), is going to look like north Bilmak. It won't stand up to even a basic quite short notice assault by a military that knows what it's doing and arrives in force.
Edit: As a test I looked at fortifications around Lyubymivka and Staromlynivka, directly north of Bilmak in the first line of Russian defences. All those trenches are in tree lines, all are either clearly saw tooth without needing to zoom in, or have firing positions in the line when zoomed in, there's also often communication trenches that extend backwards away from the trench line. They just look more thought out and better constructed. Likely the troops and what they're armed with will match the better prepared trenches they're in. Still should stand no chance against a concentrated attack.
