Testing web map APIs - Google vs OpenLayers vs Leaflet

Geospatial technologies evolve quickly, here's a fresh comparison of web mapping API and libraries, Testing web map APIs - Google vs OpenLayers vs Leaflet.

From the conclusion: "Google, for example, can easily insert adverts into its maps without us knowing. Leaflet and OpenLayers, being open source, cannot. That said, if your aim is just to get attractive 'off the shelf' maps up quickly, Google Maps is a good option. OpenLayers is mature and big and works well with servers. Leaflet, as the new kid on the block is the most exciting for me and encapsulates many of the benefits of open source software in general: speed of development, flexibility, efficiency. [...] Lightness considered, for me that would mean Leaflet for many applications, but watch this space for the final version of OpenLayers3 (due very soon) and perhaps even better web mapping options."

MapCentia GeoCloud integrate Open Source Geospatial Software

A couple of years ago I started developing MyGeoCloud an open source project that ties PostGIS, MapServer, TileCache and OpenLayers together in one integrated geospatial solution. Since then a lot has happen with the project: The development has moved from a big consulting firm to a small startup called MapCentia, the project is renamed to MapCentia GeoCloud, the codebase is rewritten and Leaflet, OpenLayers3 and Elasticsearch are included in the stack.
The goal of the project remain the same: Provide an all-in-one open source solution for storage, geospatial operations, geospatial web services and web mapping.
A more detailed description of the project can be found

Boundless Releases OpenGeo Suite 4.0

Major Advances for Leading Enterprise Geospatial Software Stack

New York, NY November 05 — Boundless, formerly OpenGeo, has released version 4.0 of OpenGeo Suite. This release brings new features and improvements, including component upgrades to PostGIS 2.1, GeoServer 2.4, GeoWebCache 1.5 and support for OpenLayers 3 and QGIS. These enhancements expand the capabilities of OpenGeo Suite, enabling enterprises to replace legacy software with a web-based open source geospatial stack.

When reached for comment about the release Juan Marin, CTO of Boundless, said “OpenGeo Suite 4.0 represents a significant step forward for our production-ready geospatial software stack. We’ve made a number of upgrades and enhancements, making it easier for customers to develop applications and set up their production systems. We’re also supporting new technologies such as OpenLayers 3.0 and QGIS. OpenLayers 3 in particular promises many improvements over the previous version and I’m proud that Boundless helped fund and develop it.”

Boundless offers OpenGeo Suite installation packages for all major operating systems. The 4.0 release includes completely reworked packages for each system, making it easier to evaluate the software, develop applications and most importantly deploy in production. Packages for Linux, Mac OS X, and application servers will be available immediately, with a Windows-specific release coming soon.

Additional developments include a GeoServer clustering extension which allows high availability and better scaling under load. With the extension OpenGeo Suite users can configure GeoServer in a database as opposed to a file system, as well as automatically synchronize multiple instances. The extension supports the configuration of GeoServer clusters in production.

OpenGeo Suite 4.0 also includes open source component upgrades and developments. Boundless has committed support for OpenLayers 3 and also has developed a QGIS plugin for OpenGeo Suite, allowing customers to utilize the latest open source developments. The OpenLayers library has been one of the most fully featured options for web mapping, and the new version, a complete rewrite, comes with many new features, leveraging modern web standards like HTML5, CSS3 and WebGL.

In July of Boundless announced support for QGIS and the QGIS community. To enhance the integration between QGIS and OpenGeo Suite this release includes a QGIS plugin, which allows for seamless management and publishing of geographic information from QGIS to OpenGeo Suite. Users familiar with desktop applications now have an easy and powerful way of configuring OpenGeo Suite components. By integrating QGIS with OpenGeo Suite Boundless offers a complete solution for creating, analyzing, publishing, and consuming geospatial data and services without the need for proprietary software.

When reached for comment on the QGIS developments, Marin said, “The QGIS plugin adds important points of integration for desktop application users, who can now easily configure OpenGeo Suite components from QGIS. This furthers our efforts to offer our customers a comprehensive spatial data platform and enables organizations interested in replacing proprietary tools with a full featured end-to-end alternative.”

A summary of other upgrades in the 4.0 release include:

  • Improved interoperability with Google. The KML module in GeoServer has been rewritten and the KML point symbolizer has been enhanced to allow features KML by itself normally wouldn’t, like stacked symbols.
  • Improved support for 3D and LIDAR point clouds. Improved support for multidimensional data. PostGIS now natively stores LIDAR data, GeoServer and GeoWebCache can better configure and filter across multiple dimensions, including time and elevation.
  • Catalog support with CSW. A GeoServer extension to support Catalog Service for Web (CSW) version 2.0.2, providing support for Dublin Core and the ISO Metadata Application Profile.
  • Mapmeter The necessary plugins to run Mapmeter, a management and analytics tool for monitoring the health and usage of production geospatial services, come pre-packaged in OpenGeo Suite 4.0. The service comes included for OpenGeo Suite customers at the Platform and Strategic levels, but is also available for purchase separately.

GeoExt 2.0.0 Released

The GeoExt community is proud to announce the release of GeoExt 2.0.0.

GeoExt 2.0.0 is the first official GeoExt version that is built atop of OpenLayers 2.13.1 and ExtJS 4.2.1. It is being released 2 weeks after release candidate 1 was published and no serious bugs were discovered.
The newest major version of GeoExt wants to provide mostly the same API you know and love from the 1.x-series. It comes with support for the autoloading-mechanism of ExtJS, support for the single-file build tool of sencha and with exhaustive documentation that is built using the same tools that the mother library ExtJs.
This release wouldn't have been possible without the sponsors of the above mentioned sprint. Also we want to thank the companies behind the contributors of GeoExt for supporting GeoExt development in numerous ways and for such a long time.
We invite you all to use GeoExt 2!
