Imagery, Scale & Measurement
Introduction
This module establishes the first anchor: a georeferenced world at 1:1 scale. You bring satellite imagery into Blender as a real-world-accurate baseline, set the 1:1 convention (1 Blender unit = 1 meter), and — in the same page — learn how to establish scale you can defend.

| Prerequisites | Unit 01 — What is Site Reconstruction? |
| Read first | Establishing the Satellite Baseline — video, then the source-reliability hierarchy |
Learning Outcomes
By the end of this module you will be able to:
- Import satellite imagery into Blender as a georeferenced baseline
- Establish the 1:1 convention so measurements are in real-world units
- Measure and check dimensions in Blender using the measurements reference
- Choose a scale-estimation approach from the source-reliability hierarchy
Module Contents
This module is a build-up from the imported baseline to trusted measurement. Work the steps in order.
The video walkthrough: bringing satellite imagery into Blender, georeferenced anchoring, and the 1:1 convention.
You'll learn: How to build the georeferenced 1:1 working environment from satellite imagery — the scale anchor for everything that follows.
The shared reference for working with units, grid, object scale, dimensions, and precision modeling in Blender.
You'll learn: How Blender's measurement system works and how to make your measurements real-world-accurate.
Knowledge Check
Test what this module covered before moving on. Questions are drawn at random from the module's pool, with immediate feedback on every answer — the questions and the options reshuffle on every attempt.
Establishing the Satellite Baseline
Check the first anchor — a georeferenced world at 1:1. Freshness, coordinates, and what a wrong scale does to every measurement after it.
