Understanding a city/ locality

Is there any field or combination of fields Ican leverage for having a quicker understanding of a city/ locality?
It would involve having an idea of the roads, knowledge of where specific subcultures are localized, highest density consciousness in an area and spotting of emerging changes in an area.


With this new DM https://forum.maitreyafields.com/t/dm-conceptual-thinking
you could understand everything.


If you’d be able to find teachers about this town and culture and download the knowledge, maybe this could help.

Or from books?

Read a few and a map.
