Polygon (Spatial) Search Arches Project
 

This mockup depicts a user-defined polygon search (represented by the yellow polygon) for heritage assets in the area of a simulated construction project. Heritage assets falling within the search polygon, and that would thus be impacted, are highlighted with icons. When a large number of heritage assets are located within close proximity in a map view, a cluster icon appears and displays the number of heritage assets that cluster represents.
