THE CHALLENGE
What needed solving
- Engineering drawings were in CAD with no coordinate system.
- Assets could not be analysed alongside other spatial data.
OBJECTIVES
What the project set out to do
- Georeference CAD drawings.
- Convert features into attributed GIS layers.
Methodology
Our workflow, step by step
01
Review
Check drawing layers, units and coordinate references.
02
Georeference
Align drawings to control points.
03
Convert
Convert to features and attach attributes.
04
QA
Topology and attribute checks.

FAQ
Questions about this project
What is georeferencing?
Assigning real-world coordinates to drawings or images so they align with other spatial data.
Can GIS data be returned to CAD?
Yes. Layers can be exported back to DWG or DXF.
