When drawing Site boundaries, use a satellite map style and look for fences or tree lines, or use the parcel boundaries. By following parcel lines, you create Sites that have a buffer between parking areas and the Site boundary. That buffer is important because a Site can be used as a geofence to determine when a vehicle enters or leaves the property. A vehicle parked too close to the boundary might register as crossing the geofence.
Other important things to remember when drawing a Site:
- Polygons cannot overlap if you have multiple Sites near each other.
- Polygons should not overlap road links not included in that facility. (These are usually public roads.)
- Some large Sites may have property that spans across streets that are navigable by the public. In such cases, you would need to:
- Create a separate custom Place for each section of the property.
- Draw separate Site polygons around each custom Place, without overlapping the public road.
In this school Site, the polygon was drawn out to the property line, rather than up against the parking lots.
In this example, two school sites were drawn with a gap in between them to avoid overlap. Each Site is associated with its own custom Place.
