You can set a default value for your fields. The default value can be a text, number or a QGIS expression. In the example below, we are going to set the default values for x and y field to be longitude and latitude.


To set up the default value for x field:

  • Download and open this example project in QGIS
  • From the layer panel, right-click on survey layer and select Properties
  • In the new window, select Attributes form


  • Select x field under the right column (Available Widgets)
  • Under the Widget Display:
  • Set the Alias to Longitude
  • Under Defaults:
    • For Default value type: x( transform( $geometry, ‘EPSG:3857’, ‘EPSG:4326’))
  • Select the option to Apply default value on update

Note that the expression transforms the point from EPSG:3857 (map and layer coordinate reference system) to EPSG:4326.

Repeat the same for y field and set the default value to y( transform( $geometry, ‘EPSG:3857’, ‘EPSG:4326’))

Ensure to save and synchronise your project.
