What is the best practice if we need to create a 'grid' of anchors for indoor navigation?

Question

'Best practice' of ASA

Windows-Mixed-Reality-Design-Core concepts-Spatial anchors

According to the 'best practice' above, it is not recommented to create a 'grid' of anchors. To my understanding this is because the sensor drift would make the 'anchor map' distorted (e.g. when you create one anchor and then walk a few meters away and place another anchor.)

My question here is What is the best practice if we really need to deploy many anchors in a building (for positioning for indoor navigation purpose). For example, is it a good idea to increase the density of anchors? Is it a good practice that "creating anchor A -> save it -> locate anchor A -> move little like 1 meter -> create anchor B -> save it"? Would that be helpful(as the move is little, so sensor drift should be little).

If this is a Unity project, you can look into World Locking Tools for Unity. It's effectively creating those many anchors under the covers.

To combine it with ASA, there are Space Pins. I don't know of a full blown sample combining ASA and WLT though.
