WebGL Earth 2: the Leaflet compatible JavaScript 3D globe powered by Cesium


To embed a 3D globe in a website with an open-source project is now really easy. If you have a simple map application made with the popular Leaflet library, you can with almost no effort turn it into 3D interactive globe with the new WebGL Earth 2 project: just replace "L." with "WE." ;-)

See the examples of use of the API:
http://examples.webglearth.org/

The globe is made only with JavaScript, using WebGL HTML5 technology. No browser plugin is required. It means it runs automatically on all modern browsers on all computers with recent graphic cards. Chrome, Firefox, Safari, IE 11+ and even the latest Android mobile devices and soon also all Apple devices with iOS 8+.

This is a complete reimplementation of our original WebGL Earth project.

Our own JavaScript rendering core has been replaced with the great open-source Cesium project to maximally gain from the open-source principles of sharing of the development efforts. We are looking forward to contributing to the Cesium project in the future, instead of developing our own separate core.

Our target is still the same: an easy to use open-source project with public API, allowing easy embedding of a modern 3D globe in websites, with out-of-the box user friendly interaction and support for mobile devices whenever possible.

In version 2.0 we have decided to emulate the popular Leaflet JS JavaScript API enriched with 3D functions for altitude, tilting and heading of the view, and flying animations on globe. The core functions are implemented and we hope to improve the compatibility of the APIs with the help of community in the future (GitHub pull requests are very welcome ;-).

The project also preserves the original WebGL Earth JavaScript API 1.0 whenever possible.

OpenStreetMap, Bing, MapBox and other tile layers can be easily used with the globe.

Custom geodata (GeoTIFF, ECW, MrSID, ...) can be easily preprocessed with MapTiler (http://www.maptiler.com) to create attractive globes, which can be hosted on any webserver without additional software, on a LAMP hosting with TileServer-php or even on Amazon S3 and other cloud storage services.

HiDPI retina map tiles for Leaflet, OpenLayers or Google Maps API with MapTiler 0.5.3

The new MapTiler 0.5.3 comes with several exciting new features:
  • Rendering of Retina / HiDPI map tiles from any raster geodata
  • Improved output into minimised PNG (better defaults for colour quantisation)
  • Support for maps crossing the international dateline (+ or - 180 degrees longitude)
  • Background colour of base maps selectable in the user interface under Advanced options
  • Google Earth API web viewer generated for KML SuperOverlay
  • Checking for updates is automated and installation of new versions simplified [Start]
  • Graphical User Interface for Linux operating system available for MapTiler Pro customers next to the command line for full automation
  • Improved Mac OS X 10.9 support (open file dialogs, upgrade to QT 4.8.6rc)
  • Better handling of thousands of input files in the graphical user interface [Pro]
  • Several bug fixes, improved stability on older Windows 
In case you are an owner of a Retina / HighDPI mobile device such as iPad or iPhone or recent tablet with Android or one of the Apple MacBook Pro Retina or Google Pixel, then have a look at examples of the beautiful retina high DPI overlay maps in Google Maps APILeaflet, OpenLayers or OpenLayers 3.
It is extremely easy to prepare such sharp maps from any raster geodata (GeoTIFF, etc) or even scanned paper maps or standard JPEG or PNG - and then upload and host them on Amazon S3, your own server or for free on Dropbox or on Google Drive hosting. See our video tutorials.

Would you like to try the MapTiler Pro demo with your own data on your own computer? It is available on request via http://www.maptiler.com/.

EPSG.io: Find Coordinate Systems Worldwide

Klokan Technologies GmbH, Switzerland (http://www.klokantech.com/) is pleased to announce a new open-source web service with a database of coordinates systems used in maps worldwide.

EPSG.io (http://epsg.io/) simplifies discovery of coordinate reference systems utilized all over the world for creating maps and geodata and for identifying geo-position. It is a practical tool for anybody interested in cartography and digital map making, who needs to know exact latitude and longitude values for numerical coordinates in different spatial reference systems. Included map application allows to show the precise location anywhere on the planet also visually.

The website comes with a fulltext search indexing over 6000 coordinate systems. The search starts by typing the name of the system, name of covered country, state or any of the combinations of these. Searching for EPSG and ESRI codes is supported as well.

Each coordinates system and transformation has a short permanent link and is exportable in various formats (WKT, XML, OGC GML, Proj.4, JavaScript, SQL).

The web has also API allowing integration of the search functionality and transformations in third party applications.

Soon this functionality will be used the by the MapTiler (http://www.maptiler.com) to simplify the transformation or existing raster geodata and images into Google Maps and OGC WMTS compatible tiles. MapTiler is the easiest way how to prepare custom maps for mobile devices and web presentation.

Georeferencer (http://www.klokantech.com/georeferencer/), the online service for turning scanned maps into geodata in a web browser, will soon utilize EPSG.io service as well - allowing a user-friendly selection of any coordinate system and map projection during the georeferencing process.

The EPSG.io website is built around the official EPSG database maintained by OGP Geomatics Committee (http://www.epsg.org/). The database comprises of very detailed geodetic parameters from a range of sources and authorities. EPSG.io simplifies access to exact parameters for thousands of spatial reference systems, transformations and conversions, datums, ellipsoids, meridians, units, etc.

The whole project is open-source - with complete source code available on GitHub: https://github.com/klokantech/epsg.io
Contribution from the online community is very welcome. New features, fixes of bugs and additional functionality can be easily developed by anybody who is interested in improvement of the system.

The web supports OpenSearch protocol. In Chrome web browser it is possible to type into address bar "epsg.io" then <tab> and your search phrase. Firefox can add the system to the list of supported search engines as well. Web site is available as Google Chrome OS application (http://goo.gl/frnJxu). The website availability and performance is improved by a CDN with over 20 caching servers worldwide.

The initial version of this open-source project has been developed by the Moravian Library in Brno, Czech Republic (http://www.mzk.cz/) thanks to support from the Programme of Applied Research and Development of the National and Cultural Identity (NAKI) from the Ministry of Culture of the Czech Republic, project No. DF11P01OVV003 - TEMAP - Technology for access to Czech map collections: methodology and software for protection and re-use of national cartographic heritage (http://www.temap.cz/en/).

The main features

  • Fulltext search for the complete database of coordinate systems from EPSG
  • Short rememberable URLs, i.e. http://epsg.io/4326
  • Type GPS latitude/longitude and get projected coordinates or vice versa
  • Precise numerical location on a map / aerial photo for any place on the planet
  • Export definitions in various formats, including WKT, OGC GML, XML, Proj.4, SQL, JS, etc.
  • Facets for retrieval of alternative record types from the official EPSG database
  • API for the search in EPSG database and for transformations

Frequently answered questions

How does the system differ from spatialreference.org and epsg-registry.org?

It is much easier to find the coordinate systems (for example query "utm wgs norway" gives list of all UTM zones with WGS covering area of Norway). 
All available transformations for selected coordinate reference system are visible and applicable (it is possible to find alternative 7 parameter transformation for Proj4js replacing a default grid transformation, or choose a transformation with higher accuracy for a selected area).
Preview location for any numerical coordinates on a detailed map - with copy&paste functionality.
Complete EPSG database with codes for datums, units, transformations, etc is indexed and searchable, and the individual EPSG records are linked from every detail page.
