FOSS4G 2011: WMS Shootout and Sol Katz Award

While at FOSS4G in Spain last year, UMN MapServer (Linux) won the annual competition WMS Shootout with Mapnik not fare behind. During this year event, for distributing vectors (PostGIS) data only : Mapnik was at its best, for vector seeding : MapServer on Linux was way much faster than the other products, for vectors and raster data : Mapnik and MapServer Linux looks better and finally for vectors, rasters and DEM data: MapServer Linux was the fastest.

At the same time, MapServer on Linux was about 3 times faster than on MapServer on Windows on some of charts! The results in details of WMS Shootout will be published soon. At the end of the conference the annual Sol Katz Award was given this year to the lead developer of the JTS Topology Suite, Martin Davis. Congratulations to the first "Java" contributor to win this FOSS4G award!

JTS 1.12 Released

Good news, JTS 1.12 has been released. It matters since a lot of other open source software uses it. GEOS, which recently went to 3.3.0, is a C++ port of the JTS. We also mentioned a month ago the new JSTS project, the JavaScript port.

From it's main website, JTS is: "The JTS Topology Suite is an API for modelling and manipulating 2-dimensional linear geometry. It provides numerous geometric predicates and functions. JTS conforms to the Simple Features Specification for SQL published by the Open GIS Consortium."

What's new for 1.12:

GEOS 3.3.0 Released

With GEOS 3.2 released in 2009, it's nice to have GEOS 3.3.0 now released. This link also provide details on the JTS features missing in GEOS. Here's the full change list for GEOS 3.3.0. In short, in addition to the usual bug fixes, "this release introduces a fair amount of new C-API interfaces and a brand new PHP binding."

A reminder of what GEOS is: "GEOS (Geometry Engine - Open Source) is a C++ port of the  Java Topology Suite (JTS). As such, it aims to contain the complete functionality of JTS in C++. This includes all the  OpenGIS Simple Features for SQL spatial predicate functions and spatial operators, as well as specific JTS enhanced topology functions. GEOS is available under the terms of  GNU Lesser General Public License (LGPL)."

It was just last week that we announced the JSTS project, the JavaScript port of the JTS.

Here's the geonews in batch mode, covering the last two weeks, and thus, longer than usual. But first, a quick note to let you know that we updated our open budget after the last donation from WebMapSolutions.com.

I've been overly busy lately, the consequence is you're getting your geonews in batch mode a little later than usual. Here they are!
