Serverside SVG Generation (with Perl)
Organizers: Ronan Oger, Klaus Förster
Target Audience
People somewhat familiar with a scripting language such as perl, python,ruby or people familiar with an object-oriented program.
Part I: An Introduction to Server-Side SVG Generation and Parsing using Perl and Other Languages
Aim of the Workshop
Attendees will be taken through a survey of server-side SVG generation techniques. The workshop will revolve around the use of the Perl SVG modules. Attendees will learn to generate a variety of SVG images starting with a simple red dot on a white background, and progressing through to complex images with imported and re-used components.
Contents Part I
The tutorial will cover the following concepts with examples:
- Overview of the current options for server-side generation
- Creating a simple SVG Drawing
- Adding Primitives: Ellipse, Rectangle, Ployline, Polygon
- Adding Details: Generating Styles and filters
- Re-using Images: Linking, Use, and Groups
- Dynamic Effects: SMIL declarative Animation and Javascript
- Server-Side DOM Queries and Manipulations
- Rendering Options
- In-line XML generation
- SVG Document Fragment
- Interaction through Javascript
Part II: Using SVG, Perl, Javascript, and a Database to create a GIS Thin-Client for multiple simultaneous users
Aim of the Workshop
The afternoon session (or 1/2 session if you decide to keep it to two) will be focused on the design and construction of a thin client based on Perl SVG, Javascript, ASV3, and MySQL.
Contents Part II
The application we will build will be a simple GIS system where drawing primitives are drawn to screen by typing in positions in X/Y boxes, or by clicking/dragging.
Each primitive will be assigned a data type and attached comment field list. The second tutorial will teach attendees how to build an SVG-based application with which two users on different browsers can be enabled to cooperate on the same document from different browsers and to demonstrate basic database interaction.
This will generate a basic but completely viable georeferencing application (except for the part about coordinate-frame transforms - but that is out of scope).
Attendees will learn how to close the loop on multi-browser interaction:
- Building a request sender method with Javascript
- Parsing xml using Javascript and ASV plugin functionality
- Manipulating the SVG drawing at the browser
- Sending xml requests in the server in the background
- Parsing xml at the server
- Saving state in a MySQL database
- Generate an SVG response
- Send the response to the browser
- Scheduler-driven browser actions
Introduction to GML
Organizers: Ron Lake (Galdos Systems Inc.)
Aim of the Workshop
This course provides an introduction to the OpenGIS Consortium's Geography Markup Language, the emerging world standard for the modeling, storage and transport of geographic information. This course will provide a strategic introduction to GML and its supporting XML technologies. The course will show how GML and SVG complement one another in geographic information services and the production of maps and other visualization products.
Target Audience
GIS Specialists with basic SVG knowledge that want to become familiar with GML
Contents of the Workshop
- Introduction to GML
- GML concepts
- Benefits of GML
- XML Foundations for GML
- GML Software Components and Tools
- GML architecture
- GML Feature Types and Feature Collections
- GML Feature relationshiops (Geolinks)
- GML Geometry classes
- GML and OGC Web Feature Services
- Presenting geographic/cartographic data with GML and SVG
- Map Styling Architectures
- Standards for Map Styling
- The future of GML
