OpenLayers Turf (olturf) is a Turf toolbar for OpenLayers. The toolbar provides the following features:
- Customizable commands to display
- Forms to collect command inputs
- Popups to display numerical outputs
- Input features are selected in the map
- Output features are displayed in the map
Instead of displaying all the Turf commands available, individual commands can
be selected or a subset of pre-defined groups can be displayed. The following
groups are available aggregation, classification, data, grids,
interpolation, measurement, misc, joins, transformation.
A toolbar can be added to an OpenLayers map by adding its dependencies
