Place mesh
Photos, map pins, notes and source links for places and routes.
A digital twin can start with a photo, a note, a source link, a map pin and a question. The important part is showing assumptions before decisions harden.

The best first twin is humble: what is seen, when it was seen, who can verify it, what is unknown, and what should stay private.

Use modelling to compare options before physical change.
Keep sensitive raw context local where possible and share only what is chosen.
Record what the model knows, guesses and refuses to guess.
People should know what is public, private, permissioned, draft or sensitive before AI, maps or simulations touch it.
