How does everything fit together?¶
The HOT Tech Team is working to improve the user experience across multiple tools, and working towards an end to end data flow between projects.
During disaster response, or a humanitarian mapping campaign, a project manager or mapper may require:
- High quality base imagery.
- Remotely mapped features, derived from this imagery.
- Field-verified information about these features.
- Data exported in a useful format for further analysis.
The goal of our proposed E2E Flow is to fill in these gaps to aid an effective response.
