  • So, You Want to Make a Map?

    by Darrell Fuhriman and skjalf

    So, you think you’ve got a great idea for a map, but little to no experience in map-making? Have you been making maps, but want to increase your understanding of what’s going on “under the hood”? Do you think maps are nothing but a bunch of latitude and longitude points? Then this session is for you.

    We’ll introduce you to the concepts you need to know to really understand how maps work: technically, visually, and even socially. We’ll cover how your data gets from the real world to your screen, why every map is a lie, how to think about your data, and how to make your data pretty and understandable. Then we’ll talk about where to find data, and just as importantly, how to understand your data, and how to make sure the lie your map is telling is the one you mean it to. Finally, we’ll talk briefly about what open source tools are out there to help you manipulate and display your data.

    At 10:00am to 11:45am, Wednesday 22nd June

  • Open Source GIS Desktop Smackdown

    by David Percy, Christian Schumann-Curtis and Darrell Fuhriman

    Open Source GIS software has proven to be reliable, fast, and cartographically pleasing on the WWW, however it has traditionally lagged behind commercial systems on the desktop.

    In this session we will highlight the capabilities of some of the leading, most feature-rich, desktop applications in the open source ecosystem. Each presenter will demonstrate a specific set of tasks from cartography to analysis in a specific software platform. The programs featured are: Quantum GIS, gvSig, OpenJump, and MapWindow.

    At 2:30pm to 3:15pm, Thursday 23rd June

  • Similar, But Not The Same: Designing Projects Around Three Open Datasets

    by Matt Blair

    Over the past year, I've been working on three projects that make open datasets available to the public:

    Although the public-facing parts of these projects appear similar on the surface -- apps or websites with locations on a map -- the design and development process has been quite different for each.

    In this talk, I'll explore the opportunities and challenges I encountered in each, covering factors like:

    • Data source -- Who gathered it, when and why?
    • Data content -- What's in it?
    • Metadata definition and stability -- Is it clearly structured? Does it follow standards? Is the structure or format subject to change?
    • Data accuracy and completeness
    • Data volatility -- How often does the data change?
    • Geographic scope -- Does it cover a neighborhood? A city? A metro region? A state?
    • Geographic density -- Is it more or less evenly distributed or are there obvious clusters and empty areas?
    • Intellectual Property -- Is the data itself clearly licensed for re-use? Does it point to other data or media that have copyright restrictions or limitations?

    I'll use this comparison to suggest a re-usable blueprint for analysis and planning of open data projects, including how to match available data to audience interests and expectations, as well as identifying opportunities for community participation.
