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)
Now the feature table only contains the features within the selected area. The tool button will have the current area shape on it. In the dropdown menu you can use one of the following options:
Show/Hide the outline and fill of the selected area
Zoom to the filtering area
Clear filtering geometry
You can use quick export to save the filtered features in a variety of common geodata formats. Click Save as and select in the dropdown menu Quick export with default settings or Advanced export to modify parameters (see detailed description below).
6.7.4. Displaying selected fields and feature edit information
You can select which fields of the feature table to display. Press “Open table settings” button in the right corner and untick the fields you want to hide.
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.
