"Lookbackmaps is a network of neighborhood historians, historical photo enthusiasts, historians, book publishers and others who collaborate to map history.
Through the online digitization of high-resolution public photo collections and geotagging technology, Lookbackmaps creates collaborative, standardized views into the past.
There's something in being human that wonders what was here before us-who occupied this space, how did they live, what did they leave behind? By mapping the millions of historical photos available through public libraries and private collections on the web, we start to piece together the puzzle."
"Waymarking is a way to mark unique locations on the planet and give them a voice. While GPS technology allows us to pinpoint any location on the planet, mark the location, and share it with others, Waymarking is the toolset for categorizing and adding unique information for that location. Groundspeak's slogan is "The Language of Location" and our goal is to give people the tools to help others share and discover unique and interesting locations on the planet. We invite you to share your part of the world with us through Waymarking.com."
"This website is an illustrated searchable online catalog of historical information viewed through the filter of roadside and other permanent outdoor markers, monuments, and plaques. It contains photographs, inscription transcriptions, marker locations, maps, additional information and commentary, and links to more information. Anyone can add new markers to the database and update existing marker pages with new photographs, links, information and commentary."
