Geographic object types and groups The types of geographic objects (a.k.a. **Geo-Object Types**) handled by GeoPrism Registry can be categorized based on how they would be represented on a map: * Fixed geographic objects that can be simplified by a point, for example: household, health facility, human settlement * Fixed geographic objects that should be represented by polygons due to their much larger extent, for examples: administrative units, health districts, or by a line due to their shape, for example: road, river * Mobile geographic objects, for example: individuals, patients, vehicles; the geography of these objects would either be obtained by considering them attached to a fixed geographic object or by simplifying them as a point that would be located through their geographic coordinates (latitude and longitude) taken at a given point in time. In GeoPrism Registry, these can be further aggregated into groups of geographic object types having the same attribute configuration (e.g., health facilities as a Geo-Object Type group could group health posts, health centers, and hospitals). --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.geoprismregistry.com/readme/current-1/geoprism-registry-key-components/5.1-content/5.1-content-1.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
