Modeling from Matched Photos
Module Overview
Both anchors are now in place: a georeferenced 1:1 world and a matched camera. This module is where you build the site — modeling structures against the matched camera, then verifying the result by photomatching (rendering from the matched camera and comparing it to the original photo). It also introduces the scale pillar: the five-level source-reliability hierarchy that keeps your dimensions defensible.
Shared reference page: the Scale Estimation page carries the full scale pillar — it is woven into the sidebar flow for this module.

Modeling Against the Matched Camera
[TODO: the practical loop — model a structure (e.g. the house), view it from the matched camera, compare to the reference photo, adjust dimensions/position until the silhouettes and edges line up. Reference the Scene Management page for keeping the scene organized.]
The Scale Pillar
[TODO: the five-level source-reliability hierarchy for scale references (from known object dimensions up to photogrammetric/point-cloud scale). Why you always state which level a given dimension rests on. Full detail on the shared Object Reconstruction reference page.]
Photomatching: The Verification Step
[TODO: rendering from the matched camera at the original image resolution, overlaying against the source photo, and what a good vs. bad photomatch tells you. This is your proof that the model is from the right viewpoint at the right scale.]
Knowledge Check
[TODO: 3 questions — e.g. what a photomatch verifies; what the scale pillar is and why it matters; what to do when the photomatch doesn't line up.]
Summary
[TODO: one paragraph.]
