  1. WMS Time Series With Mapbuilder Michael Adair Natural Resources Canada EOGEO’05

  2. Agenda • Introduction to Mapbuilder • Demos OSGIS’05 Technical Session

  3. Introduction • Leverages Open Geospatial Consortium (OGC) specifications for web mapping: Context, WMS, … • Retrieves XML documents (and images) dynamically at run-time using HTTP (AJAX) • Renders XML documents to HTML using the browser’s built-in XSLT processor • Object-oriented architecture using the Model-View-Controller (MVC) design pattern Mapbuilder is an Open Source JavaScript framework for implementing web clients in a structured and modular manner OSGIS’05 Technical Session

  4. Features • Client is a web browser • AJAX + browser XSLT + DHTML + DOM • Highly interactive and responsive clients – no “reload” buttons! • Minimal server side requirements • Modular Object-Oriented design - Highly extensible and configurable • Open source (GPL) • Supports OGC standards • Coordinate transformations in JavaScript • Multilingual support OSGIS’05 Technical Session

  5. MVC design pattern Model • maintains the state and data of the application - the XML document View • A rendering of the XML document Controller • The user interface presented to the user to manipulate the application The MVC pattern forces one to think of an application in terms of three object types: OSGIS’05 Technical Session

  6. How the Time Series works • OGC WMS and Context documents support the Dimension element: <Dimension name="time" units="ISO8601“> 2004-04/2005-04/P1M, 2005-06-15,2005-06-15 </Dimension> • Mapbuilder generates a sequence of GetMap requests with timestamps - stacked and looped • WMS request means that zooming, layer overlays, etc. are supported OSGIS’05 Technical Session
