How to Keep Up With Changing Web Mapping Technology

Directions Mag offers an article named Research Explores How to Keep Up With Changing Web Mapping Technology, starting with 'change is inevitable: deal with it'.

From the results: "Despite the fact that the Google Maps API delivered on more of the requirements set out in the Needs Assessment Survey, the team selected Leaflet as the answer to the first question of which technology should be used for teaching. Leaflet was, in fact, second best in supporting the requirements, but the Diary Study suggested students made more progress and felt better working with that set of libraries. The team suggests that might be due to the added transparency and control provided by a fully open source library."

FOSS4G Geonews: GeoServer CSS vs SLD, Cesium, SplashMaps, Open Bank Project Maps, and more

Here's the recent FOSS4G geonews.

In open source software updates:

  • GEOS, the Geometry Engine Open Source, got to version 3.3.6
  • The popular GeoServer got to version 2.2.2
  • Another bug fix release is the OpenGeo Suite version 3.0.1
  • It's not the end, GeoTools 8.4 was released

In the everything else category:

  • Here's an entry on the GeoServer CSS module, that presents itself as an alternative and improvement over the SLD (Style Layer Descriptor) OGC standard: "GeoServer CSS is inspired by the web—and by great tools like Carto, Cascadenik, and MapCSS. Like these tools it provides a concise styling syntax modeled on CSS but differs in that it’s goal is to improve the experience relative to SLD while preserving CSS concepts like cascading. While we ultimately aspire to a common CSS-like styling language for web cartography, we hope that GeoServer CSS is much easier than SLD and will be familiar enough for web designers to use."
  • Arnulf links to the SplashMaps Kickstarter project that uses open data, "real outdoors maps; based on open data, on light, weather friendly fabric" (image below)

OpenLayers 3 – Call for Funding

3D Maps, WebGL, CSS3 ?

Consider funding OpenLayers in order to use these great new possibilities:

OpenLayers 3 leverages the latest in browser advancements, with a full WebGL map renderer and a DOM/CSS based renderer where WebGL is not available. OpenLayers 3 will build on the vector rendering and editing functionality in the current version, supporting standards and community formats and protocols. The new version of the library will focus on performance, with a lightweight build optimized for mobile browsers, and usability, with an overhauled website and learning resource center. We’re excited to be giving OpenLayers a design and performance facelift while maintaining the breadth of functionality that OpenLayers users depend on.

First open source initiative for CARIS

Fredericton, NB, Canada – July 18, – CARIS, the world's leading marine GIS organization, has released its first open source API. CARIS OSCAR-js, a JavaScript Map API, allows you to create and embed custom web maps on your website.


The API was created to help shape CARIS Spatial Fusion Enterprise and includes tools for navigation, measurement, and download, as well as providing a means for developers to create their own custom tools and extensions. OSCAR-js extends the very popular OpenLayers library and utilizes jQueryUI and YUI to help create a feature rich mapping experience.


The API is designed around the creation of map themes. Map themes consist of thematic maps along with optional functionality such as selection, data download or more. OSCAR-js supports the use of Open Geospatial Consortium (OGC) web services including Web Map Service (WMS), Web Map Tile Service (WMTS), Web Feature Service (WFS) and Web Coverage Service (WCS) for creating these map themes.


In addition to supporting OGC web services, OSCAR-js can connect to CARIS Spatial Fusion Viewer to load map configurations. This allows for centralized site management for your web map infrastructure.


The source code for the API is available on GitHub under the Apache License 2.0. This will enable the development community to make their own development branches for customization or as a way to contribute code to the project. Building your own distribution is done easily using Maven 3.

To get started, visit the OSCAR-js website. Users will find helpful API documentation, code examples, as well as a blog to hear the latest information about OSCAR-js.

Notemap it: Online Map Redlining

A critical need among map users is usually due to annotations and redlining. People want to take notes and share maps easily. This is more and more a need in a social network driven timeframe.

Notemap.it has been developed aiming at this. It is a small webGIS designed to draw lines and polygons on the map, with customized style. It also let the user to add markers, notes, icons and more. Once the maps has been saved a sharable personal URL is given back to the user. Notemap is built upon OpenStreetMap, OpenLayers and Dojo.
