Poly-on-Poly

The Customer Service Representative (CSR) uses a map to identify the excavation area. PRISM can incorporate a wide variety of geo-coded layers to permit using a number of different points as reference: mile post markers, parcel boundaries, etc. CSRs can also access publicly available mapping systems (Google Maps®, Bing®, Yahoo®, etc.) on-the-fly if the location can’t be matched with the center’s base map.

Excavation Area

The excavation area is the full extent of the actual dig site. PRISM identifies the dig site based on a hand drawn polygon created at the time of the call. PRISM can also use regularly shaped grids to identify the notification area if a call center chooses.

Excavation Polygon

Whether polygons or grids are used to establish the general area of the dig site, they both create an Excavation Polygon. If the Excavation Polygon boundary crosses a Database Polygon, the facility operator that “owns” that Database Polygon gets the ticket.

Database Polygons

Database Polygons define the area in which a facility operator wants to receive tickets. They can be irregular shapes or grids of a fixed shape and size. PRISM is flexible enough to accommodate either one (or both).
