Building a Data Collection App with QGIS
summary
Shows how to turn a QGIS project into a working data-collection app using QField or Mergin Maps, with concrete steps: create point/line layers, set field types and lengths, use value map dropdowns and multi-line notes, configure a photo field to store attachments relative to project and reduce image size, and add auto-fill username and datetime expressions. Uses QGIS plugins to publish and sync (cloud or self-hosted), produces a web map or Python/Dash outputs and one-page per-point Word reports with embedded photos; the workflow is tested and usable.
