Stakeholder consultation
Initial consultation completed with NICD, UCT and CSIR to define:
- Priority disease areas (malaria, NCD)
- Required EO indices and data products
- Dashboard output formats for public health decision-makers
Data source definition

Prototype wireframes
The working prototype is deployed at:
👉 https://main.d1jko0jkg4m7f.amplifyapp.com/
Current prototype capabilities:
- Malaria risk map for Limpopo (7,384 ward-month records)
- Time slider: Jan 2025 – Jan 2026
- Region drill-down: Province → Municipality → Ward
- Risk level filter (High / Moderate / Low)
- Environmental factors panel
- NCD risk module with Southern Africa choropleth
Dataset produced
The primary dataset for Milestone 1 is Limpopo_Risk_Jan25_Jan26_Safe.csv:
- 7,384 records across 9 municipalities
- 13 monthly snapshots (Jan 2025 – Jan 2026)
- 13 EO-derived variables per ward per month
- Extracted from Google Earth Engine
Outstanding activities
- Final architecture sign-off by UCT/CSIR
- Prototype wireframe review session with TuksNovation
- Submit design specification document to NeoFrontiers
- Close-out report for Milestone 1 (due 16 March 2026)
Draw-down
Upon completion of all Milestone 1 deliverables and submission of close-out documentation, R 250,000 will be drawn down against the total R 1,000,000 budget.
