Labs at FOSS4G provide regular attendees the opportunity to explore one topic in detail, often in a hands on setting.

L-01: Raster Processing and Preparation with GDAL

A practical tutorial on processing and preparing raster data for visualization or futher analysis.

L-02: Practical Introduction to MapBuilder

MapBuilder is a powerful, standards compliant geographic mapping client which runs in a web browser. This workshop will explain how to work with MapBuilder to present maps and other information in your web pages. The first half will be a beginner level tutorial including a short introduction, and the second half will present more advanced concepts.

L-03: Datums, Coordinate Systems, Map Projections & Datum Transformations

This lab is for developers, users, geographers, and aims to answer many questions faced in our day-to-day use in Open Source Mapping and to importantly show that latitude and longitude are not absolute.

L-04: Rapid Visualization with the Virtual Terrain Project Software

Learn to use the cross-platform open-source VTP software to turn your geospatial data into interactive real-world visualization. This step-by-step class will lead you through processing standard data formats and raw GIS files into visually realistic terrain, roads, buildings, water and trees, even dynamic elements such as vehicles.

L-05: Introduction to FDO and the FDO API

The Introduction to Feature Data Objects (FDO) workshop will present an overview of FDO and its Application Programming Interfaces (API). Using examples and tutorials it will introduce users to the concepts, organization and structure of FDO.

L-06: Practical Introduction to MapStorer

MapStorer is a database supported system for managing MapServer projects. MapStorer makes it possible to maintain MapServer mapping projects via an easy-to-use web frontend and re-use definitions of layers and classes across existing mapfiles. This workshop gives an introduction to setting up and using MapStorer.

L-07: CartoWeb for Beginners

CartoWeb ( is both a comprehensive and ready-to-use Web-GIS and a convenient framework for building customized applications. It is based on Mapserver.

L-08: An Introduction to the uDig Open Source Desktop

Learn the basics of the uDig open source desktop application! Load data from multiple sources, reproject, edit, re-style, using data from the desktop, the web, and databases, all at once.

L-09: Using the GeoNetwork open source Spatial Data Catalog

GeoNetwork is a standards based and decentralized spatial information management environment, designed to enable access to geo-referenced databases, cartographic products and related metadata from a variety of sources, enhancing the spatial information exchange and sharing between organizations and their audience, using the power of the Internet. This approach of geographic information management provides a wide community of spatial information users with easy and timely access to available spatial data and to existing thematic maps that support informed decision-making.

L-10: Defining and Using Custom Cartographic Symbols in MapGuide

Defining and Using Custom Cartographic Symbols in MapGuide introduces participants to the new XML formats for defining symbols in MapGuide. In the workshop participants will create a small symbol library and use the symbols for styling points, lines, polygons, and labels in MapGuide.

L-11: Protecting OGC Web Services with the 52°North Security System

This workshop demonstrates how to add authentication and authorization capabilities to spatial data infrastructures with the services of the 52°North security system. The participants will be guided to set up and configure the necessary access control services to protect an OGC Web Map Service and load it into an OGC WMS client.

L-12: Introduction into OGC's Sensor Web Enablement

OGC Sensor Web Enablement will reach version 1.0 in 2007. After six years of developing, the specifications are considered to be mature enough to be published as OGC specifications. 52°North is has a major thread dedicated to SWE services and encodings exclusively, covering all those services like SOS, SPS, SAS, and WNS.

L-13: How to Cope with GeoSpatial – The Pragmatic Intro for the Java Developers

Are you new to GeoSpatial? Are you not cool enough to be a Neo-Geographer AJAX empowered meta tagging Ruby wonder kid? Does scientific mumbo-jumbo make your head hurt? Are you (gasp!) just out to get the job done? Come to this workshop and go home happy.

L-14: Leveraging PostgreSQL with ESRI's ArcGIS system

Introduces GIS users & developers to ESRI's new support of PostgreSQL and Linux in the ArcGIS framework

L-15: FME as a Two-Way Bridge between Proprietary Systems and Open Source Databases

This workshop demonstrates Safe Software's FME technology as a bridge between open source technology and proprietary GIS systems. FME allows open source databases, GDAL-supported formats and OGR formats to be used with proprietary GIS systems, adds value to FDO data providers, and extends the functionality of GEOS to many formats.

L-16: Deegree iGeoSecurity – Access Control for OGC Web Services

The workshop will give an introduction into deegree iGeoSecuirity, the security framework of the deegree project. The setup and configuration of secured services will be exercised using a practical example.
