Removing all the geo data

You may want to remove all the indexed nodes from the spatial tree. You can do this by removing all the layers, which is a rather expeditive method indeed.

Try this code, which should return an empty list :

// Removing all spatial layersCALL spatial.layers() YIELD name AS nameWITH collect(name) AS namesUNWIND names AS nameLCALL spatial.removeLayer(nameL)  // enamel layer :)call spatial.layers() YIELD name AS name2WITH collect(name2) AS emptyNamesListRETURN emptyNamesList

I hope you enjoyed this chapter, particularly rich in puns and wordplays.
