Dwilhelm89/Ethermap. GitHub: Bringing GeoJSON To Life Since 2013. Last week, the code repository heroes over at GitHub made an awesome announcement: Any .geojson files living in GitHub repos will now be rendered on a Leaflet-driven, OSM tile-backed map right inside of GitHub, with tooltips showing the data properties to boot!

GitHub: Bringing GeoJSON To Life Since 2013

This is a truly exciting moment for all geonerds who code, developers who use geodata, and everyone in between. “Hey, wait a minute,” you may be saying. “What is GitHub again? And GeoJSON… I think I’ve heard of that, but what is it for?” Do not fret! Git and GitHub Before learning about GitHub, we first have to understand git. In order for multiple people to work on a project, the data has to live in a place where multiple people can access it, right? Because git is so great, and GitHub is so popular, people have been using it for all kinds of projects, coding and otherwise.

Here is a documentation on all of them, along with examples and download links. Source files reside along MapBBCode in its GitHub repository.

OSM Tchoutchou - Raildar with Open Street Map. Mobile-Friendly Mapping for PhoneGap Apps - Modern Web. By Rob Lauer One of the first and most enduring features of mobile devices was, and continues to be, mapping.

Mobile-Friendly Mapping for PhoneGap Apps - Modern Web

The ability to locate yourself on a map with the tap of a finger, anywhere in the world, has arguably influenced adoption of smartphones and tablets as much as any other feature. Building a mobile mapping application. Leaflet mobile mapping application Our earlier articles on mobile application development demonstrated the process of getting an app up and running on an Android phone using Adobe PhoneGap and GitHub.

Building a mobile mapping application

For the purposes of this article we’re going to assume that you are now comfortable with that process and will demonstrate how easy it is begin building mobile mapping applications. This is something we are developing a lot of interest in here at Cranfield University. As with previous examples, the app is going to be based on a package of HTML, CSS and JavaScript code and will therefore use one of the many JavaScript web mapping APIs available. Loading OSM data. This guide describes how to install, set-up and configure all the necessary software to have a database of OpenStreetMap data which you can use to render maps or develop stylesheets.

La conversion directe de données géographiques vers le GeoJSON peut produire des fichiers de taille trop importante, qui seront longs à charger et à exploiter. Plusieurs techniques permettent de réduire le poids de ces fichiers.

Back in October 2011 Google announced it would start charging the heaviest users of Google Maps and would eventually start inserting ads for other users.

Initially Google’s price was set at $4 per 1,000 map views but has since been reduced to 50 cents per 1,000 views. In light of these developments, agencies are increasingly being asked by clients – some of whom are looking at potential bills of tens of thousands of pounds a year – to look for cheaper alternatives. Luckily for developers, there are many alternatives – with more being developed all the time. What’s really exciting about these new kids on the block is that, rather than being second-rate Google Maps knock-offs, they are producing some really beautiful, characterful maps. While Google Maps being free was great for site owners, it wasn’t necessarily so for app-builders, or the end user, as it suppressed the development of alternatives. 20 superb data visualisation tools for web designers.

It's often said that data is the new world currency, and the web is the exchange bureau through which it's traded. As consumers, we're positively swimming in data; it's everywhere from labels on food packaging design to World Health Organisation reports. As a result, for the designer it's becoming increasingly difficult to present data in a way that stands out from the mass of competing data streams. One of the best ways to get your message across is to use a visualization to quickly draw attention to the key messages, and by presenting data visually it's also possible to uncover surprising patterns and observations that wouldn't be apparent from looking at stats alone.

And nowadays, there's plenty of free graphic design software to help you do just that. As author, data journalist and information designer David McCandless said in his TED talk: "By visualizing information, we turn it into a landscape that you can explore with your eyes, a sort of information map. 01. 02. 03. 04.
