Are there any areas in the maps where a lower area extends beneath a higher area? If not, could you use a single block of acrylic and just laser-ablate to different depths instead of cutting each layer separately and then gluing?
I don't know if all laser cutters support that kind of operation, but I had some badges and a wax seal stamp like that made at a makerspace about a decade ago. I brought in PostScript files[1] where different colours were assigned to different depths on the cutter. The depth was remarkably precise and consistent - it looked like it had been performed using a tiny CNC router.
[1] I think? I made them in InkScape, but the makerspace couldn't use SVGs directly.
