Session Type: 
Tech Session
Presenter(s): 
Justin Deoliveira, in affiliation with OpenGeo
Andrea Aime, tech lead, GeoSolutions

2011 marks the 10 year anniversary of the GeoServer project with 2010 - 2011 being the most successful year yet. GeoServer continues to grow with an active community and expanding user base. This presentation takes the pulse of the project with a status report of how GeoServer is doing and what to expect in the coming future.

The presentation will start with a "year in review" overviewing some of the new and noteworthy of the past year. This year saw the coming of GeoServer 2.1, a major milestone for the project that brought some exciting new features along with it. Cascading WMS, Virtual Services, SQL Layers/Views, Unit of Measure support for SLD, WMS 1.3, and WPS are just a few of the highlights of 2.1. Attend this presentation to get the entire report of what happened this past year.

The GeoServer developer community continues to remain active with a number of exciting features in the pipeline. The remainder of the presentation will focus on the future with a report of the new developments currently being worked on and what new features and improvements users can expect in 2012.

Whether you are an expert user, a developer, or simply someone who wants to know what GeoServer is and what it can do for you, this talk is for you.

Speaker Bio: 

Andrea Aime and Justin Deoliveira both sit on the GeoServer project steering committee and are active contributors to the GeoServer and GeoTools projects. Andrea is currently a senior software engineer with GeoSolutions S.A.S. Justin a technical lead at OpenGeo.

GeoServer on steroids

Session Type: 
Tech Session
Presenter(s): 
Mr Simone Giannecchini, GeoSolutions
Mr Andrea Aime, GeoSolutions

Setting up a GeoServer can sometimes be deceptively simple. However, going from proof of concept to production requires a number of steps to be taken in order to optimize the server in terms of availability, performance and scalability.

The presentation will show how to get from a basic setup to a battle ready, rock solid installation by showing the ropes an advanced user already mastered. The topics that will be covered in details include:

  • choosing the appropriate output formats to avoid network bottlenecks
  • optimize vector and raster data for the deep multi-resolution displays typical of web GIS
  • optimize styling to provide a good balance between map navigability and performance, identifying common performance pitfalls in the styling options
  • setting up caching with GWC for the background layers, identify layers and situations that are not suitable for caching
  • configuring WMS/WFS/WCS service limits so that no single request can consume too many server resources
  • defend against peak hour load by using the control-flow extension
  • using the monitoring extension to control the server in production and identify sources of trouble (long request, clients making too many/too heavy requests, layers and services used the most that could use more tuning attention)
  • load test a OGC service with JMeter

The presentation will end with real world examples of enterprise deployments of GeoServer implemented by the author as well as its colleagues at GeoSolutions during the years.

Speaker Bio: 

GeoSolutions Founder, OSGEO Charter Member, Simone Giannecchini has been involved with geospatial open source software since early 2004, playing an active role sine early 2005. He has a leadership role in several projects, like GeoServer, GeoTools, ImageIO-Ext and JAI-Tools.

Efficiently using PostGIS with QGIS

Session Type: 
Tech Session
Presenter(s): 
Vincent Picavet, Oslandia

PostGIS is the reference OpenSource spatial database everyone uses. QGIS is the dynamically growing desktop GIS everyone will be using. Using both together should therefore be a blast!

QGIS allows connecting to a PostGIS database for long, and if you stay with this bare functionality, it works seamlessly. But taking the most out of this couple needs a bit of experience and can be complex.

This talk gives you an insight on how to use efficiently QGIS with POSTGIS.

  • Core functionalities of QGIS related to PostGIS
  • Comparison of the numerous plugins to connect to this spatial database (RT SQL Layer, PostGIS Manager, PGQuery, offline editor, versioning)
  • Tips and tricks on how to use them efficiently
  • Interaction with other tools (PgAdmin for example) * Corner cases and limitations * low level implementation and consequences

The presentation will close with perspectives for the future, stating the current situation and explaining what will and could be done to improve the interaction between these two softwares. Feedback from the public on their own experience will be an opportunity to try to define the best way of improving the way we use PostGIS and QGIS.

Speaker Bio: 

Vincent is involved in Open Source GIS for a while, PostGIS contributor, he created Oslandia with Olivier Courtin in 2009 to provide services on FOSS4G. He often speaks about this subject in international conferences.
