San Francisco requires commercial property developers to provide publicly-accessible facilities referred to as Privately Owned Public Open Spaces or POPOS. Some can be quite spectacular, but many are overlooked, unknown to the public, or simply not recognized as public spaces. Cataloging POPOS is a minor art in the region, with even a couple of native apps to be found on the Apple and Google app stores.
This demonstration shows how through the use of tag filtering and interest-based authoring, a contributor can put together a location-based guide. In this example, it’s to cover public open spaces, but you can imagine similar guides for historical markers, city libraries, pubs, sports facilities, etc.
