workshops - tuesday

tuesday morning
XML and XQuery, and Their Application to Spatial Information	Dr. Michael Kay, Technical Director, Saxonica
This half-day tutorial will be in two parts . Part 1 will provide an introduction to XQuery: both at the coding level (understanding the basic language constructs), and in terms of its architectural role and capabilities relative to other technologies. Part 2 will work through a case study showing applications of XQuery to information with a strong spatial dimension - with the aim of showing not only what the language is capable of, but also where its limitations lie.

GeoSpatial Data Quality	Dr. Michael Goodchild, Professor of Geography, University of California, Santa Barbara
Data quality is an increasingly important issue for the GeoWeb, where it is encountered in the form of semantic vagueness, misregistration, and uncertainty over the results of mashup and overlay. The workshop begins with the definitions of basic terms, including scale, accuracy, precision, and vagueness. Examples are used to illustrate the significance of the problem. Each major type of geospatial data has its own characteristic quality issues, from positional accuracy of vectors to the vagueness of classes in area-class maps and artifacts in digital elevation data. The relevant standards are reviewed, along with results of recent research and software for dealing with quality issues. The workshop ends with a discussion of the legal context of geospatial data quality. Examples and illustrations are used wherever possible, and participants are encouraged to bring a laptop.

A Complete Guide to Geo-Spatial Technology at Microsoft\(SOLD OUT)	Ed Katibah, Principal Program Manager - SQL Server Spatial, Mark Brown, Senior Product Manager - Virtual Earth,
Microsoft has made significant R&D investments over the past few years in an effort to build the best geospatial platform in the world and there is some incredible technology behind it all. Join us as we’ll go deep on the three main areas of R&D Microsoft has done. In this session we’ll explore the upcoming release of SQL Server Spatial and go into detail on how being the last to market allowed us to create an architecture that represents technology-forward thinking in Spatial database design and the benefits it brings the next generation of Spatial application design. Next we will discuss the investments Microsoft’s has made in aerial camera technology as well as the R&D in our 2D and 3D image and data processing that provides the underlying rich platform within Virtual Earth. And finally we will show you the fruits of our labor and show you the applications that can now be built using the entire Virtual Earth Platform with SQL Spatial together.

GML and Related Technology(SOLD OUT)	David Burggraf, Director of Research and Development, Galdos Systems, Inc.
This half-day course will provide participants with an overview of Geography Markup Language (GML) and other related technologies. Participants in this course are typically technical or business professionals with interests in the geo-spatial domain who wish to gain working knowledge of GML. A mix of slide presentations and online demonstrations will illustrate how GML is created and used by OGC Web Services. All registrants will receive a soft-cover copy of the GML Book.

tuesday afternoon
BIMStorm Vancouver	Kimon Onuma, President, Onuma, Inc.
This is a live hands-on-workshop which will educate the participants in how to use BIM, BIM Model Server, Google Earth, SketchUp and other web based tools. This workshop will allow users the ability to log in at the event or remotely to learn how to collaborate in real time with actual sites in Vancouver. This session will create a BIM and land it on Google Earth with an iPhone or PDA and will demonstrate first hand how anyone can participate in BIM. Additionally we will cover the design of buildings, master planning, engineering, energy, security and more. Prior to this live workshop in Vancouver a website will be opened up for participants to engage in the preparation for the live workshop. Actual sites in Vancouver will be studied during the workshop, such as the project, Central Waterfront Hub Study & Whitecaps Stadium Review, http://www.vancouver.ca/commsvcs/currentplanning/whitecaps//. BIM does not need to be complex to be powerful.

LiDAR: Understanding the Basics of Pulsing Lasers in the Creation of 3D Digital Point Datasets	Mike Watry, General Manager, QCoherent Software
LiDAR (Light Detection and Ranging) is an active remote sensing technology that is rapidly becoming the predominant technology for generating large-scale elevation datasets. Commonly integrated into airborne platforms, but also collected from terrestrial/ground stations, LiDAR presents a challenge to integrate into geospatial applications due to the large size of the point datasets. The resulting LiDAR point data is a 3D cloud that is post-flight processed for positioning and then classified in order to identify surfaces and features. The workshop will provide an introduction to the principals of LiDAR including how LiDAR is collected, processed, and the current ASPRS (American Society for Photogrammetry and Remote Sensing) LAS file format standard. The benefits of using the point cloud versus fixed derivates will be presented. Also shown is how LiDAR point cloud datasets can be dynamically combined with vector data and imagery in mapping environments. Beyond visualization, useful processing tasks of LIDAR QA and LIDAR by-product generation will be presented as well as how surface models can be improved by combining LIDAR data with breaklines. Students will be provided handouts of the presentation (no hands-on workshop activities), along with a demo version of QCoherent’s LIDAR software for use after the workshop.

Map Based RIA Development Using Adobe Flex and AIR	Duane Nickull and James Ward, Adobe, Inc.
Adobe Flex and AIR use the open source Flex SDK and compiler. This course is for people who want to learn how to program Flex and AIR applications for purposes of using Geo-spatial components and data to build interactive map based mashups. During the tutorial, attendees will build 5-20 applications and learn the ins and outs of RIA and desktop application development using the Flex Open Source environment. Prerequisites: knowledge of XML, some programming knowledge good not required.

Registries for the GeoWeb	David Burggraf, Director of Research and Development, Galdos Systems, Inc.
The OGC recently passed the ebRIM profile of the Catalogue Standard, which provides a flexible means to manage a wide variety of artefacts arising in GeoWeb applications. For example, sensors, observations, crs, symbology/styles, schemas etc., in addition to more conventional dataset descriptions and service offers. The course covers the ebRIM and WRS standards and shows you how to deploy the WRS in practice. All use cases will be illustrated using running examples in a WRS.
