Géolocalisation
Un article de Wikipédia, l'encyclopédie libre. Schéma de principe de la géolocalisation par GPS La géolocalisation ou géoréférencement est un procédé permettant de positionner un objet (une personne, etc) sur un plan ou une carte à l'aide de ses coordonnées géographiques. Cette opération est réalisée à l'aide d'un terminal capable d'être localisé (grâce à un système de positionnement par satellites (et un récepteur GPS par exemple) ou à d'autres techniques) et de publier (en temps réel ou de façon différée) ses coordonnées géographiques (latitude/longitude). Les positions enregistrées peuvent être stockées au sein du terminal et être extraites postérieurement, ou être transmises en temps réel vers une plateforme logicielle de géolocalisation.

Comparison of photo-sharing websites[edit] Legend: References[edit] L'irrésistible ascension de la géolocalisation Cela devait arriver. A force de remplir son mur sur Facebook, de bavasser sur Twitter, de planter des check in sur Foursquare à chaque fois qu'on met les pieds dans une boutique, on a fini par exciter la convoitise des professionnels du marketing. Leur objectif ? Prouver aux annonceurs que la relation entre la marque et le consommateur ne se limite plus simplement aux rayons d'un magasin ou à son site internet, mais qu'elle est devenue omniprésente et permanente. Bingo ! Il suffit que je me promène dans une rue commerçante avec mon smartphone en poche pour recevoir directement des alertes, par SMS, sur des offres promotionnelles proposées dans le quartier. Boostés par l'explosion du marché des smartphones - soit un tiers des téléphones mobiles vendus en France -, les services de géolocalisation engendrent un buzz très fort. Le syndrome du "check in fatigue" Véritable concept fourre-tout, la géolocalisation a commencé à se développer en 2005. Le second souffle Des questions éthiques

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. 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] Geotagging standards in electronic file formats[edit]

geolocalisation qsparis [licensed for non-commercial use only] / FrontPage Unshake How to Use Unshake. How to Install. Unshake 1.5 is a Java-2 and C program which improves blurred and shaken photographs by working out the form of the blurring, then deducing what the picture would have looked like if it had not been blurred. Because it is written in Java, once you have installed Sun's Java 2 all you have to do is to unzip one file to install Unshake on your computer. Also included in this distribution is a library and command-line filter for Linux, UnshakeC1.5r1. Unshake is offered free for personal use. This is an example of what it can do; Below is a small part of a picture I took with a cheap Polaroid camera, blown up to 600 dpi. Unshake can also remove dithering and rasters, and it can work through the lines found on magazine pictures, though for copyright reasons I can't put examples of Unshaken magazine pictures on the website. But the real point of Unshake is that it does it automatically. For more examples, click here... or here Installation
