portable GPS car navigation systems - OpenLR™ - Open, Compact an OpenLR™ - Open, Compact and Royalty-free Dynamic Location Referencing TomTom is launching OpenLR™ as royalty-free technology and open Industry Standard, and it invites the ITS Industry to join and adopt it. This step will facilitate new business opportunities in various areas of Intelligent Transport Systems (ITS) such as traffic information services, map content exchange and Cooperative Systems where precise and compact dynamic location information is needed. OpenLR™ will help to enhance existing applications and will generate opportunities for new services. TomTom will lead the further development and maintenance of the OpenLR™ system and invites the stakeholders in this industry to enhance OpenLR™ and contribute to its evolution. The official web site of the OpenLR™ project is Coverage Comparison TMC vs OpenLR™ location referencing (Main area of Berlin, DE) What is Location Referencing? The process of encoding a location is also called Location Referencing.

Studio What are Style Components? A Style Component is a group of associated layers that together represent a common cartographic feature. “Roads” and “Place labels” are examples of components. Components wrap thousands of decisions made by our cartographers into a simple, curated set of controls for color, typography, and feature density. Each component includes built-in styles, as well as a set of options unique to the features the component contains. What are the benefits of the Style Components in Studio? Components make customizing maps easier and faster in Studio by reducing the number of decisions needed to get the desired outcome. How do I start using Style Components? Any new style you create in Mapbox Studio will automatically have components enabled. How do the color and typography settings work? Color and typography settings are shared across every component in a style. Can I customize the map in ways that aren’t supported using just the components interface? No.

Quick Start Guide ← Tutorials This step-by-step guide will quickly get you started on Leaflet basics, including setting up a Leaflet map, working with markers, polylines and popups, and dealing with events. Preparing your page Before writing any code for the map, you need to do the following preparation steps on your page: Now you’re ready to initialize the map and do some stuff with it. Setting up the map Let’s create a map of the center of London with pretty Mapbox Streets tiles. var mymap ='mapid').setView([51.505, -0.09], 13); By default (as we didn’t pass any options when creating the map instance), all mouse and touch interactions on the map are enabled, and it has zoom and attribution controls. Note that setView call also returns the map object — most Leaflet methods act like this when they don’t return an explicit value, which allows convenient jQuery-like method chaining. Next we’ll add a tile layer to add to our map, in this case it’s a Mapbox Streets tile layer. Markers, circles and polygons

PC World - Great Free Files: 20 Fantastic Open Source Downloads The very earliest days of the PC revolution were soaked in idealism. People shared their knowledge with one another freely; the very idea of charging for software was an anathema. The early days of the Internet had a similar rosy view of the world. Today, of course, all that has changed. This idealism can create great software. Gephi - The Open Graph Viz Platform Google announces Summer of Code results; Drupal gets TWENTY slot We are thrilled to announce that Google will be sponsoring 20 Drupal projects for Summer of Code 2007. The students, their projects, and the mentors for each are listed below. As the summer progresses, these students will be turning to the community for support and for help testing their work. To keep up-to-date with all of the latest SoC developments, please join the SoC 2007 working group and help out in whatever ways you can. The projects this year show a strong focus on the core Drupal software and the infrastructure that makes run. For example, the translation, metrics, and RCS abstraction projects all intend to make project management on better in some way. Two projects focused on staging and scalability will help make Drupal more robust, two projects focusing on Drupal file handling will help shore up known weaknesses in that area. Thank you to Google for the unbelievably generous support.

Hydrodynamic Submarine :: Create the Future Design Contest *It is an invention of most extreme simplicity. *It consists only in a new design of the hull, which the shape is cylindrical and where the water is sucked in the prow, passing through internal side ducts and being expelled in the stern. *The hydrodynamic submarine is “pulled” by the low pressure of the water that is sucked in its front, besides being pushed for the high pressure of its propulsion. *Near to the propeller’s spin occurs a great pressure difference. *In the conventional model the low pressure of the water is not used as pulling force. *** New, non-obvious, useful (PCT/WIPO 2012). 1)The Hydrodynamic Submarine does not push the water, but pulls the water, that pulls the submarine. 2)The sucked water in the prow is repositioned in the stern. 3)Possessing cylindrical shape, it doesn’t externally moves the water. 4)Two are the causes of the movement resistance in the water:1ª The heavy water mass to be moved (main cause).2ª The roughness of the hull (secondary cause).
