In order to use wayfinding in your application, you first need to create the wayfinding graph using the editor available in the IndoorAtlas web application. The following video tutorial demonstrates the usage of the editor.

Directed edges

An edge beteen two different floors can be made directed by selecting the edge and then clicking the +directed button that appears on the toolbar. The direction is determined by which node was clicked first when creating the edge. Reversing the direction of an edge can be done by first removing the old edge and then creating a new one, this time beginning from the correct node.

Accessibility

Starting with SDK version 3.7, IndoorAtlas supports accessibility criteria in wayfinding routes. Edges in the wayfinding graph can be tagged as inaccessible (not suitable for e.g. wheelchairs), or accessible-only (intended only for e.g. wheelchairs, such as special elevators). A wayfinding route can then be requested with the criteria of avoiding inaccessible or accessible-only edges. See this article for instructions on how to use this feature in our SDK.

Tagging the graph edges is easy to do in the IndoorAtlas web app. Simply select an edge by clicking on it and click the icons on the right-hand-side to add a tag. Wayfinding with the accessibility tags can also be tested in the web tool.
