- Agree criteria and weights with stakeholders.
- Produce a ranked suitability surface.
- Shortlist candidate sites.
Methodology
Our workflow, step by step
01
Criteria

03
Overlay
Weighted overlay and constraint masking.
04
Ranking
Shortlist and compare candidate sites.

FAQ
Questions about this project
What is multi-criteria analysis?
A method that combines several weighted factors, such as access and slope, into one suitability score.
Can weights be changed?
Yes. Scenarios can be rerun with different weights to test sensitivity.
