An essential practice when manually entering or editing spatial data for a connected network is to use the ‘snapping’ tool. The snapping tool snaps feature end points to other feature end points when the mouse cursor enters the ‘snapping range’ of the specified destination point. Snapping ensures topological connectivity of the network. All spatial network data was entered and edited using the snapping tool.
An extra precaution taken when entering and editing the walking network, in addition to snapping all features, was to also slightly overlap crossing links on the base walking network, then planarise the edits. This method ensured if an intersection or road crossing link was not correctly snapped to the base network, then the link overlapping the base network would always connect by creating an intersection at the point of overlap.
