:''The decision to map a parking lot landmark is covered here, and the decision to map a parking lot road is covered in the [[Road_Types_(USA)#Parking_Lot_Road|Road type article for mapping parking lot roads]].''
Few parking lots deserve to be landmarked. Landmark-worthy parking must be something of a destination in itself, either having a well-known and documented name, or serving multiple unrelated POIs.
In nearly all situations parking associated with any other landmark, such as a shopping mall or train station, '''should NOT be landmarked separately using the Parking Lot type. ''' It is sufficient simply to include such parking within the boundaries of the other landmark. In the rare case of named parking that drivers might wish explicitly to seek, such "double landmarking" of parking within a larger landmark may be acceptable, for example a cell- phone Parking Lot landmark within the boundaries of an Airport landmark.
Defining the boundaries of Parking Lot landmarks requires care.
Like the Gas Station landmark, Parking Lots suppress Waze's automated "Map Problem" reports such as for missing roads; thus '''the Parking Lot landmark should NEVER be drawn over or attached/snapped to roads bearing through traffic.'''
While Waze provides a Garage landmark type, the Parking Lot landmark should be used, when appropriate, for parking structures and garages both above and below ground as well as for ordinary lots at ground level.
The Parking Lot landmark is '''always appropriate for''':
* Generic Park & Ride and similar municipal commuter parking not otherwise landmarked with a transit-center type.
Always name these "Park & Ride", or whatever generic designation is used locally, to facilitate searches. Mapped at the fence line.* Municipal general-purpose or transit-oriented public parking that has a unique and documented identity, such as "City Lot #7", "Hourly Lot 3", "Domestic Garage", "Long-Term Parking", "South Lot", "Cell-Phone Parking", etc. Map to the extent of the lot or structure and assign the given name. If the lot is contained within a larger landmark, do not repeat that landmark's name; for example if the Domestic Garage is contained within the "SFO San Francisco International Airport" landmark boundaries, it can simply be labeled "Domestic Garage" not "SFO San Francisco International Airport Domestic Garage".* Rental car return located on airport property, provided all on-airport vendors share the same car return area (to avoid having to label separate return areas by commercial vendor), named "Rental Car Return".
The Parking Lot landmark is '''NEVER appropriate for''':
* Parking for a single non-transit-oriented destination, whether public or private, such as a business, office, church, park, city hall, library, hospital, gym, school, museum, restaurant, campground, etc. Do not use the Parking Lot landmark for these even if apparently supported, and widely used, as general-purpose parking; Waze cannot imply that drivers should, for example, park in the City Library Lot in order to visit a café or go shopping, even if locals often do so.
* Employee, student, resident, or guest parking.
* Parking for attendees of events or services.
* Parking associated with campuses, parklands, shopping malls, theme parks, private installations, and office parks or complexes of any size or purpose.
* Generic unnamed/unidentified parking lots associated with an already-landmarked complex such as an Airport, Train station, or Bus Station/Bus Terminal.
A gray area exists between the "always appropriate" and "never appropriate" categories above.
Indeterminate situations include, for example: * Unnamed municipal general-purpose public parking.* Privately-operated but publicly-available general-purpose or offsite transit-related parking.
At this time, landmarking indeterminate situations like these is not encouraged, but may be appropriate in some circumstances and handled on a case-by-case basis.
