QGIS Labs QGIS Tutorial Labs Home This is a set of tutorial labs for Quantum GIS, an open source geographic information system. The labs are based loosely on labs in my course ABT 180. The labs are based on QGIS version 1.7.3 (last updated 5/1/2012). I would appreciate hearing comments and suggestions. The labs make use of the following data sets: Field 5 (this is a wheat field located in Central California) Brown's Pond (this is a data set first used in Geographic Information Systems and Cartographic Modeling by C.
Polymaps Examples Enjoy these sample visualizations built with Protovis. For any example, use your browser to view the source or the backing dataset. Protovis is no longer under active development.The final release of Protovis was v3.3.1 (4.7 MB). The Protovis team is now developing a new visualization library, D3.js, with improved support for animation and interaction. D3 builds on many of the concepts in Protovis; for more details, please read the introduction and browse the examples. Conventional While Protovis is designed for custom visualization, it is still easy to create many standard chart types. Area Charts Bar & Column Charts Scatterplots Pie & Donut Charts Line & Step Charts Stacked Charts Grouped Charts Custom Many charting libraries provide stock chart designs, but offer only limited customization; Protovis excels at custom visualization design through a concise representation and precise control over graphical marks.

OpenLayers Simple Example Available languages — Deploy an OpenStreetMap slippymap on my own website. For a more up to date example use leaflet instead. This simple example may help if you are Deploying your own Slippy Map. Note: OpenStreetMap is serving the tile images Please note that tile images are coming from the OpenStreetMap servers. If you are expecting heavy user load, then you should discuss with everyone first (Contact). Of course the images themselves (our maps) change over time too, not necessarily for the better. Instructions First, create a folder to work in. The smallest example <! The code shows how you initialise a Map object with a DIVs id add a OpenStreetMap Layer force the tiles to show by calling zoomToMaxExtent, you could also call zoomToExtent, but for that you need a bounds object in the correct projection... A little more extensive example Extensions Other tile sets If you are deploying your own tile images (for example, with Mapnik), just use the layer definition below: Add Markers <! like so: Related
Protovis Protovis composes custom views of data with simple marks such as bars and dots. Unlike low-level graphics libraries that quickly become tedious for visualization, Protovis defines marks through dynamic properties that encode data, allowing inheritance, scales and layouts to simplify construction. Protovis is free and open-source, provided under the BSD License. It uses JavaScript and SVG for web-native visualizations; no plugin required (though you will need a modern web browser)! Although programming experience is helpful, Protovis is mostly declarative and designed to be learned by example. Protovis is no longer under active development.The final release of Protovis was v3.3.1 (4.7 MB). This project was led by Mike Bostock and Jeff Heer of the Stanford Visualization Group, with significant help from Vadim Ogievetsky. Updates June 28, 2011 - Protovis is no longer under active development. September 17, 2010 - Release 3.3 is available on GitHub. May 28, 2010 - ZOMG! Getting Started
