6.7.3. Filter layer features on the Web Map by area

NextGIS Web has a tool in the Feature table that filters all layer features within a selected area. To choose area limits just draw them on the Web Map.

Open the feature table and click on the button with a dotted frame. In the dropdown menu select the geometry of the area:

  • circle (click twice on the map, to choose the center of the circle and its size, the radius length is shown in meters)

  • line (features intersected by the line will be filtered)

  • rectangle (click on diagonally opposite apexes)

  • free-hand drawn polygon (each click creates an apex, the area covered by the polygon is highlighted; to finish the shape, double-click on an apex, the polygon will be completed automatically)

  • Show/Hide the outline and fill of the selected area

  • Zoom to the filtering area

  • Clear filtering geometry

If feature versioning is enabled, at the bottom of the list you’ll find an additional unticked field. It is a virtual “Last changed” field. It contains date and time of the most recent edit made to the feature as well as the username.

The first change logged is the time the versioning is enabled.
