"Some people interpreted the Geotaggers' World Atlas maps to be maps of tourism. This set is an attempt to figure out if that is really true. Some cities (for example Las Vegas and Venice) do seem to be photographed almost entirely by tourists. Others seem to have many pictures taken in piaces that tourists don't visit."

"Dimensions takes important places, events and things, and overlays them onto a map of where you are."

"After a few API calls and some code and graphics work, I’ve got a map showing the colors of the physical-cultural landscape around Harvard Square. This is not simply a map of the colors on the ground, which you can get from an aerial photo or systematic documentation like Google Street View, but rather a map of the colors that people on the ground are looking at."

"A Place Page is a web page for every place in the world, organizing all the world's information for that place. And we really mean every place: there are Place Pages for businesses, points of interest, transit stations, landmarks, and cities all over the world. To find a Place Page, click on "more info" in your Google Maps search results or "more info" in the info bubble on the map."

"The challenge for startups (and investors!) has been identifying opportunities that are "native" to the new platforms. By "native" we mean opportunities that simply did not exist previously and cannot exist without the phone. For instance, we would not consider delivering breaking news to a mobile a native opportunity, as a startup rarely has a better chance of being "CNN for mobile" than CNN does. Native opportunities are the ones that make use of unique capabilities of mobile platforms."

"Indiemapper was built for cartographers like us. We were tired of altering our mapping work-flow to fit expensive software designed for graphic designers and GIS-technicians. We're not alone. Map-makers, novice and professional alike, are frustrated with their existing choices. Why can't these tools better reflect the way we actually work?

We also know that there are a lot of under-served map-makers who only make a few maps a year (scientist, political aid, real estate developer). Indiemapper is packed with enough expert knowledge on color, typography and map-design to turn your data into great maps every time."

"Finder is a browser-based application for finding, organizing and sharing GeoData in common formats. Search the world's geodata or upload your own."
