Climate Health Analytics Platform (CHAP)

CHAP is a platform for forecasting and for assessing forecasts of climate-sensitive health outcomes. In the early phase, the focus is on vector-borne diseases like malaria and dengue.

The platform can perform data parsing, data integration, forecasting based on any of multiple supported models, automatic brokering of compatible models for a given prediction context and robust forecast assessment and method comparison.

This documentation contains technical information about installing and using CHAP. For more general information about the project, we refer to the CHAP project wiki. The documentation here is divided into sections referring to different use-cases:

---

Full installation and integration with DHIS2

For users who want to fully install CHAP locally or on a server, e.g. to integrate with DHIS2, we recommend setting up CHAP with docker compose and using the Prediction app.

---

Integrating external or custom models with CHAP

For users who want to develop custom forecasting models and run or benchmark these through CHAP, or to simply evaluate external models on small example datasets, we recommend installing the chap-core Python package and folowing the guides on integrating external models and developing custom models.

---

Using CHAP as a library

For users who want to use CHAP as a library, we refer to the tutorials and API documentation (see the menu).
