ODK documentation

ODK is an open-source tool that allows users to build forms for data collection using either a mobile app or a web app. Data collection can include GPS locations, photos, numerical values, categorical data, etc., and can be collected offline, with synchronization occurring once an internet connection is available. The gathered data can be sent to and retrieved from a server called Central, either using ODK Cloud services or a self-hosted infrastructure.

This guide outlines the quick setup of forms on a Central server to make them accessible to different app users, whether via a mobile app or a web app. The guidelines include a description of how to conduct field observations and later access the data through the Central server or an API that allows querying and loading data locally.

The workflow is built using available documentation from ODK Docs and online tutorials from the ODK YouTube channel. This guide does not cover the installation of the Central server on own infrastructure or its setup using ODK Cloud services. It assumes that the Central service is already deployed, tested, and fully operational.

For more information on setting up the Central server, visit the official documentation.
