Glossary

Please read through these explanations of the symbols used throughout the maps.

	A green circle indicates the building's principal, ground floor entrance. Where more than one entry point exists, an entrance is determined to be the "principal entrance" based on architectural intent, ease of access, location, and use.
	A yellow circle indicates the building's non-principal, ground floor entrance. All non-principal access points receive this designation regardless of architectural intent, ease of access, location, or use.
	A dark blue square, coupled with one of the circles above, indicates the entrance is accessible. An entrance is "accessible" when no physical barrier exists immediately inside or outside the door. Physical barriers include curbs, narrow doorways, raised thresholds, steps, and other impediments that would inhibit a wheelchair user from accessing the building. For example, an entrance leading only to a flight of stairs would not be "accessible."
	A dark magenta square, coupled with one of the circles above, indicates the entrance has an automatic door opening function. Please note, this designation does not differentiate between push button door openers and doors with automatic sensors. Where push button openers exist, this designation indicates only their presence and not the size or location of the buttons. Please refer to the photographs, where available, for this information.
	A light blue square, coupled with one of the circles above, indicates the entrance is via an elevator. These elevators are either on the outside of a building or immediately inside a door. Maps do not show the locations of elevators within the buildings themselves.
	A solid yellow line indicates the location of a ramp. This element appears frequently throughout the maps.
	A solid green line indicates the location of an access point along a sidewalk. This element appears infrequently throughout the maps, and access points do exist even where not noted.
	A solid red line indicates the location of a physical barrier. This element appears infrequently throughout the maps, and bariers may exist even where not noted.
