Building on the success of HOT's Tasking Manager, a tool for coordinating remote digitization of map features, the Field-TM was conceived with the purpose of tagging the features with field-verified information.
While there are many excellent applications for tagging map features already, the Field-TM aims to solve the problem of coordinating field mapping campaigns.
- Project is created in an area with three things:
- Data extract: the features you want to map, say building polygons.
- ODK XLSForm: the survey for mappers on the ground to fill out for each feature.
- Task areas divided by feature count and linear features (e.g. rivers, roads).
- Users assign a task area for themselves, then map using ODK Collect, ODK Web Forms, or QField.
- User navigates to the feature and fills out the XLSForm survey, then submits.
- The submissions are collected by ODK Central (or QFieldCloud), which feeds the data back into Field-TM, for cleaning, conflation with existing data, and pushing back to OSM.
This project relies heavily on the ODK ecosystem underneath:
- XLSForms are used for the underlying data collection survey. The fields in this survey can be mapped to OpenStreetMap tags.
- ODK Central is used to store the XLSForm and receive data submissions from users.
- ODK Collect is a mobile app that the user submits data from.
In the wake of the 2010 Haiti earthquake, volunteer developers created the Tasking Manager after seeing a similar coordination challenge for mapping areas without existing data.
Now with over 500,000 volunteer mappers, the Tasking Manager is a go-to resource for volunteers to map collaboratively.
To aid future disaster response, we would really welcome contributions for:
- Backend Python development (Litestar + HTMX)
- Documentation writers
- UI / UX designers
- Testers!
- XLSForm creators
Please take a look at our documentation and contributor guidance for more details!
