OpenGeo Suite 3.0 is Out!

Newest version of the OpenGeo Suite has just been released and it comes with the following goodies.

  • Server-side processing
    • OGC Web Processing Service (WPS) provides a standard for inputs and outputs (requests and responses) for geospatial processing services such as polygon overlays, buffers, or custom processes.
    • Rendering transformations make processing operations easier in browser-based visualizations by enabling just-in-time use of any WPS process as part of any layer’s style.
    • Server-side scripting in Python and JavaScript allows users to easily deploy their own server-side processes using concise and straightforward APIs.
    • PostGIS 2.0 brings vector and raster analysis into the database.
  • GeoServer security now supports user groups as well as a number of new authentication mechanisms including LDAP, digest and X.509 certificate authentication.
  • Virtual services allow GeoServer to support multi-tenancy, enabling a single GeoServer instance to publish multiple service endpoints.
  • A new caching configuration interface in GeoServer includes the ability to define new grid sets, specify which layers to cache, seed or truncate the cache, and more.
  • OGC Web Feature Service 2.0 (WFS) adds some interesting new capabilities, including paging, stored queries, and extended operators.
  • Upgraded components, including the adoption of GeoServer 2.2PostGIS 2.0, and GeoWebCache 1.3

GeoServer 2.2 Released

Almost a week ago, one of the most popular web mapping server engine has been updated, GeoServer 2.2 has been released. As they wrote: "The release of a new major version update is a big deal (the last one was over 16 months ago) [...]", here's some of the highlights, follow to link to get the full overview!

  • NTv2 and NADCon Support allows for datum transformations with cm level precision
  • Continued work for supporting high accuracy datum transformations
  • A new reprojection console
  • The image collection coverage store allows users to serve un-referenced data through WMS using image/pixel space as the coordinate system
  • Support for WFS 2.0 adds some interesting new capabilities to the WFS protocol
  • Support for additional dimensions brings time and elevation support to both vector and raster data. And, with support for time, comes support for animation in WMS.
  • GeoWebCache configuration GUI is now available directly from within the GeoServer web admin interface

And much much more...

Rasdaman: Geospatial Raster Data Manager

I had to investigate OGC's WCS standard and in the process I learned about Rasdaman, a geospatial radar data manager software which is apparently the only software that currently support WCS 2.0 both as a server and client. Rasdaman exists both in a commercial 'rasdaman enterprise' version and as open source with the 'rasdaman community' version. We never really mentioned rasdaman before.

The rasdaman community introduction: "Rasdaman extends standard relational database systems with the ability to store and retrieve multi-dimensional raster data ( arrays) of unlimited size through an  SQL-style query language. On such sensor, image, or statistics data appearing, e.g., in earth, space, and life science applications rasdaman allows to quickly set up array-intensive services which are distinguished by their flexibility, speed, and scalability.

Rasdaman is brought to you by the guys writing the geo raster standards, including  OGC WCS and  WCPS, the OGC raster query language. The petascope component of rasdaman provides service interfaces based on the  OGC  WCS,  WCPS,  WCS-T, and  WPS. For several of these, rasdaman will be reference implementation. Since April 2011, rasdaman is available on the  OSGeo Live DVD. Rasdaman embeds itself smoothly into  PostgreSQL; further, a  GDAL rasdaman driver is available, and likewise a  MapServer integration (beta). A  PostGIS query language integration is under work, see our planning. EarthLook is a demonstration site showcasing rasdaman in a variety of 1-D to 4-D geo use cases."

OpenGeoDa: An Introduction to Spatial Data Analysis

Via the OGD blog I learned about OpenGeoDa, an open source software program that serves as an introduction to spatial data analysis. The initial (closed) version was released in 2003 and they claim about 70,000 users. While we mentioned GeoDa before, it's really the first time we share about its existence with our users.

Here's what it is: "It is designed to implement techniques for exploratory spatial data analysis (ESDA) on lattice data (points and polygons). The free program provides a user friendly and graphical interface to methods of descriptive spatial data analysis, such as spatial autocorrelation statistics, as well as basic spatial regression functionality. The latest version contains several new features such as a cartogram, a refined map movie, parallel coordinate plot, 3D visualization, conditional plots (and maps) and spatial regression."

Mapnik 2.1.0 Released

I'm back from holidays - thank you for your patience. Expect several days for me to catch up geospatial news and share them with you. You can always submit anything pertinent directly.

Last November we mentioned the major 2.0 release, and now, Mapnik 2.1.0 has been released. Mapnik still is "a free Toolkit for developing mapping applications. Above all Mapnik is about making beautiful maps. It is easily extensible and suitable for both desktop and web development."

Here's the highlights for 2.1.0: "

  • A new framework for Style level image manipulation called Image filters.
  • A new pipeline for chained coordinate transformations like clipping or smoothing called Vertex Converters
  • Compositing modes at Symbolizer and (experimental) Style level. Infinite possibilities from this, see a few examples from AJ.
  • Support for Style level opacity
  • WKT, WKB, GeoJSON, SVG parsers and generators that can be used outside of rendering
  • Data-driven SVG style transforms on svg markers and images thanks to @lightmare
  • Data-driven orientationfor Text, heightfor Buildings, and width/heightfor Markers.
  • A new CSV input plugin
  • A new GeoJSON input plugin
  • A new Python input plugin
  • Better text labeling through support for placement-type="list". See the docs at the bottom of this page.
  • Improved Map loading speeds as well as warnings and errors"
