# Capturing field data

In the last step we created a project which will be used for our field survey. Let's now practise capturing some field data.

Note that the background map used in this project requires network connectivity. To display it outside, you need to be connected to the internet.

  1. Open the project by tapping its row in the Projects screen. You should see your location shown over the background map:
    Current location shown on OpenStreetMap

  2. Pinch the map to zoom in to your current position. If needed, recentre the map using the GPS button in the bottom navigation panel.
