# Mergin Maps Input Interface

Below is a description of various items within the user interface.

The map can be moved by dragging around and zoomed in/out by pinching open/close. Tapping on a feature displays the attributes form.

There are four tabs available in the bottom navigation panel: Projects, GPS, Record and More.

  • Longitude, Latitude: current position
  • X, Y: current position in project's coordinate reference system
  • Horizontal and Vertical accuracy of the GPS position
  • Altitude: ellipsoidal height
  • Satellites (in use/view): number of satellites
  • Speed
  • Last fix: time of the last received GPS position
