After four months of stitching all those high-resolution pics together, the company’s Street View maps of the Canyon are live and ready to be clicked through. The maps don’t document the entirety of the 277-mile-long Canyon, but they do offer a trip along two of its most popular trails, both of which are on the southern rim: the Bright Angel Trail to the Phantom Ranch campsite and the South Kaibab Trail. “We’re really happy with the way all the images came out,” said Ryan Falor, a Google Maps product manager. Photo: Ariel Zambelich/Wired The Grand Canyon was the maiden voyage for Google’s Trekker — a backpack-like camera that takes 75-megapixel photos and weighs 40-pounds. “We don’t have our next stop hammered down yet, but we certainly want to take Trekker to every country that we’re doing Street View in,” Falor said.
ELETTRONICA OPEN SOURCE | News ed Articoli Tecnici di Elettronica e Tecnologia The Mobile City » Blog Archive » Cartography: the old versus the On December 14th 2009 De Balie – an Amsterdam-based center for culture and politics – organized an evening about old and new cartographies. Participants were Ferjan Ormeling (Emeritus Professor Cartography, Faculty of Geographical Sciences, Utrecht University), Henk van Houtum (Associate Professor of Geopolitics and Political Geography, Head of the Nijmegen Centre for Border Research), Maarten Keulemans (science journalist), Jelle Reumer (director Natural Museum Rotterdam, Special Professor at Utrecht University), Lucas Keijning (NEMO science center), and me. The evening was lead by Volkskrant journalist Martijn van Calmthout. We have been making maps for centuries, to establish territorial borders or mark safe routes. Cartographer Ferjan Ormeling started the evening with an overview of cartography as a professional scientific discipline. Then Henk van Houtum and I joined the discussion.
Whatever Rumsey Historical Map Collection The David Rumsey Map Collection was started over 25 years ago and contains more than 150,000 maps. The collection focuses on rare 18th and 19th century maps of North and South America, although it also has maps of the World, Asia, Africa, Europe, and Oceania. The collection includes atlases, wall maps, globes, school geographies, pocket maps, books of exploration, maritime charts, and a variety of cartographic materials including pocket, wall, children's, and manuscript maps. Items range in date from about 1700 to 1950s. Digitization of the collection began in 1996 and there are now over 55,000 items online, with new additions added regularly. Maps are uniquely suited to high-resolution scanning because of the large amount of detailed information they contain. With Luna Imaging's Insight® software, the maps are experienced in a revolutionary way. Materials created in America and that illustrate the evolution of the country's history, culture, and population distinguish the collection.
Grassroots Mapping » What is Grassroots Mapping? January 27th, 2010 by Jeffrey Warren A group of activists, educators, technologists, and community organizers now known as Public Laboratory came together to organize the Gulf Oil Mapping project. Since May 2010, we have been working with New Orleans-based Louisiana Bucket Brigade to get Gulf Coast residents out on boats and along beaches to produce high-resolution aerial imagery of the spill’s effects. All the imagery from this project is being released into the public domain Read more How it started This January 2010, Jeff Warren worked with a series of organizations and communities to produce maps with children and adults from several communities in Lima, including the Cantagallo settlement of Shipibo on the bank of the Rimac and the Juan Pablo II community in Villa El Salvador. Seeking to invert the traditional power structure of cartography, the grassroots mappers used helium balloons and kites to loft their own "community satellites" made with inexpensive digital cameras.
angiemckaig.com Geotagging Geotag information in a JPEG photo, shown by the software gThumb The related term geocoding refers to the process of taking non-coordinate based geographical identifiers, such as a street address, and finding associated geographic coordinates (or vice versa for reverse geocoding). Such techniques can be used together with geotagging to provide alternative search techniques. Geotagging techniques[edit] The geographical location data used in geotagging will, in almost every case, be derived from the global positioning system, and based on a latitude/longitude-coordinate system that presents each location on the earth from 180° west through 180° east along the Equator and 90° north through 90° south along the prime meridian.[citation needed] Geotagging photos[edit] There are two main options for geotagging photos; capturing GPS information at the time the photo is taken or “attaching” the photograph to a map after the picture is taken. GPS formats[edit] JPEG photos[edit] Audio/video files[edit]
