The Humanitarian Data Model
OpenStreetMap historically has been geared for mapping in developed countries, in nonemergency situations. During the HOT's first participation in a humanitarian crisis (Haitian Earthquake 2010), the OSM tagging sufficed, but it was less useful to organizations working in traditional GIS modes. Field responders need to know easily how OSM tags relate to their existing data models, and how to include new types of things in OSM, features that may be relevant only in disaster response, recovery, or development contexts.
The Humanitarian Data Model (HDM) seeks to reconcile schemas from many humanitarian response agencies, all of which are based on field requirements. When possible, this model matches humanitarian attributes to existing map features in OpenStreetMap.
With the expectation of new functionality in the HOT Export tools that can transform tag values for export files, the tagging scheme has been pushed to line up completely with OSM standards. The newest presets being used can be seen in the "Humanitarian Data Model presets" section.

Best practices for OSM tagging in HOT
- Most importantly, follow the tagging guidelines listed in the Task Manager. As a result of needs from OSM users on the ground and OSM's decentralized nature, the meaning and usage of a particular tag may change.
- Do not rely heavily on tagging schemes used in your local towns. For example, a dirt highway that you would tag in your hometown as a highway=path, may not necessarily be the most appropriate tag in other places. This dirt highway may be the most traveled within a small town. Use other contextual clues (width of highway, whether or other buildings are near it, whether it is the only road to a small village, etc) and the general description on the tag's wiki page.
- Check the geographic area's OSM wiki page (if they have one) for any guidelines of how local mappers and stakeholders tag features.
- Use consistent tagging. For example, if you see that other squares in the tasks are using highway=path, use highway=path instead of highway=footway.

Requirements from the Field
This section brings input from humanitarian responders into the Humanitarian Data Model.
So far we've been engaging with PAHO/HFacs on Health Facilities. MINUSTAH roads data. And UNSDI-t from the Logistic Cluster.
We need to flesh out these details in a new subpage, with the available materials, and level of approval/review/use.
Usage and Suggestions from OSM
This subpage brings input from the OpenStreetMap community into the Humanitarian Data Model. Idea is to continually review OSM community activity and discussion, then align, adjust, and/or extend the Humanitarian Data Model accordingly. And Vice Versa.
Covers: Tags in current use. Proposals for new kinds of things that need tagging.
