Let's go step by step.
Considering the number of effects, it is at least a major enchanted item. Depending on the number of effects and their magnitude, we will see if a Talisman is required to squeeze everathing we need into the item.
For any effect requiring to gather information without seeing the target, the range needs to be Arcane connection (+4 to base effect). The alternative with the scope of the map being a well defined region - which does not change - to havea range of touch (+1), with a target of Boundary does not work since spell with Boundary are ritual.
The target of most spell will be Part (+1), with several increase for size modifier (+3 covers a mile radius, +4 covers 4 miles radius, +5 for 13 miles radius: each time the surface increases by 10 times).
Duration will be Instant, just enough time to gather the information and have the Imaginem spells display the info on the map.
Amongst the effect to be considered:
InTe 30: Sense the feet that tread the earth to track movement of people
To have a mapping of an Area, InTe base 4 (see an object and its surroundings) seems appropriate - the Arcane connection will be with said object, with an Arcane connection which is stabilised. Herbam and Aquam réquisits are needed to map rivers, forests and what not. So the overall effect will be InTe (Aq, He) 45 Arcane, Part (+3). You can increase the range by removing the requisits, but you will need a different spell for the rivers and the forests (InAq, InHe). A spell of level 50 becomes a ritual, thus cannot be fitted into a magical item.
To have it diplays on a map to be seen by everybody, it is more than a cosmetic effect: The Land as it Is
Either CrIm 1 to affect one sense, possibly 2 or 3 if the mage wants to include smells and sounds. Range will be limited to self (the map is modifying its own appearance), duration will be either Sun, Moon or Conc (with the item maintaining the concentration). It will definitely need the "Linked effect" for +3, to be able to display the information collected by the mapping spell.
To detect the mood of a crowd (like a town): base effect 5, target group (+2) + size modifier of +2 to +5 to capture large settlement. But it will need to be cast multiple times to cover several towns/villages/city otherwise it will only return the info of the overall population.
To display the information, it probably needs a different CrIm spell (same magnitude and conditions of the previous one): The Spirit of Men as it is.
To map out Regios, it is an InVi base 3 effect, with the usual +4 for Arcane connection, +1 for Part, and +3 to +5 for the size modifier.
It is a beautiful project, very well suited for a Mercere magus.
Regarding scrying, if there is any magus or covenant in the area, detecting the mood and the Aura can be considered as Scrying. On the other hand considering that the effect won't be invested with any Penetration, Parma and Aegis will block the effect. But cautious will be needed depening when and where it is used.
