This tool build lines based on the original base points dataset and the output displaced points. This is more for testing, but can be used as an easy visualisation of how far points have moved.
The base point dataset. Note that not all the points in this dataset are required to be in the output so you can use the base dataset to link to displaced points which were the subset of the input.
The ID field from the base layer that is used to link to the displaced points.
The layer of displaced points generated from the input layer. All points in this layer should also be present in the base layer. If they are not IDs will be written as warnings in the log.
The ID field from the displaced points to link to the original base dataset. Allowing for different ID fields gives the tool a bit more utility, and allows for you to make updates to the displaced points layer.
A polyline dataset with points built from the points in the base layer to the corresponding points in the output layer. The points are attributed with the ID of the shared points.
