Can Calibrated maps only be on the top layer?
Answered
In other words, why can't I choose it as the base map?
thanks

Hi,
The reason comes down to what a calibrated image actually is inside Locus Map versus what a base map needs to be.
When you calibrate a map image, Locus saves it as a georeferenced overlay — a single picture "pinned" to real-world coordinates and placed on top of your active map. You'll find it in the Items tab of your data manager, and it sits as a layer above your background map.
A base map works differently. Base maps (LoMaps, online map sources, or offline raster maps) are built from tiles across many zoom levels, which lets them render smoothly as you zoom and pan across large areas. A single calibrated picture doesn't have that tiled structure — it's one flat image covering a limited area at a fixed resolution — so it can't serve as the continuous background layer the map engine relies on.
In short: a calibrated image is designed to sit on a base map, not to replace it. That actually works in your favor — you keep all the detail and routing of a proper base map underneath, with your custom image layered on top exactly where you need it.
If your goal is to have your own image behave like a true switchable base/offline map, that's possible, but it requires converting the image into a tiled map format (such as SQLite/MBTiles) using a third-party tool before importing it.
