PrerequisitesModule 01 — What is Site Reconstruction?
Read firstEstablishing the Satellite Baseline — the video walkthrough

Description​

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 — through the composed measurements and scale-estimation references — learn how to measure and establish scale defensibly on top of that baseline.

What You'll Be Able to Do​

By the end of this module you will be able to:

  1. Import satellite imagery into Blender as a georeferenced baseline
  2. Establish the 1:1 convention so measurements are in real-world units
  3. Measure and check dimensions in Blender using the measurements reference
  4. Choose a scale-estimation approach from the source-reliability hierarchy

What's Inside​

This module is organized as a build-up from the imported baseline to trusted measurement:

Phase 1: The Baseline

Establish the georeferenced world

Phase 2: Measurement & Scale

Measure and anchor trust

Establishing the Satellite Baseline​

Establishing the Satellite Baseline: 6 min read

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.

Measurements, Scale & Dimension​

Measurements, Scale & Dimension: 15 min read

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.

Scale Estimation & Source Reliability​

Scale Estimation & Source Reliability: 12 min read

The scale pillar — the source-reliability hierarchy for establishing scale from geospatial, physical, and environmental sources, with error propagation.

You'll learn: How to establish scale defensibly and report its uncertainty.
