Sight and grid size

[Barbamaus]

Grid size should be decreased to match sight range. It's very annoying how the map gets explored but you don't actually see everything in that grid square once it unlocks, since your sight range is lower than the map grid itself. Grid size should match sight range.

[Harunobu]

Kinda agree. You can think you have explored a region, but a Localized Resource may be hidden in that area of the map, with you not being able to know you haven't explored that area.

Either the idea proposed by the OP or some kind of mask/indicator for areas where we do know the geography, but have not been explored yet Localized Resource-wise.
