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. The evening was set up as a prelude to the presentation of a new world map the day after in The Hague. From the announcement: We have been making maps for centuries, to establish territorial borders or mark safe routes. A map is a model of reality, and the terrain of a fascinating branch of science: cartography.
Then Henk van Houtum and I joined the discussion. A Weblog About Maps. (e)space & fiction. GeoCommons. OpenStreetMap. 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. 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.
