  • A Gentle Introduction to GIS

    by Jason Scheirer

    Datums! Coordinate systems! Map projections! Topologies! Spatial applications are a nebulous, daunting concept to most Pythonistas. This talk is a gentle introduction into the concepts, terminology and tools to demystify the world of the world.

    This talk will have multiple parts:

    • What is GIS?
    • Cartography
    • Analysis
    • Geodatabases
    • Types of data
    • Vector
    • Raster
    • How do you talk about spots on earth?
    • What is a datum and why does it matter?
    • Spatial reference systems: WUT?
    • Map projections: what's appropriate and what's web mercator
    • Great circle distances and geodesy (or, your lines are wrong and you should feel bad)
    • Analysis
    • Overlay operators
    • Clementini operators
    • Buffer, clip their friends
    • Will demonstrate concepts with commercial tools (the ArcGIS stack) and some open source (GDAL, OGR, QGIS).

    At 1:20pm to 2:15pm, Saturday 10th March

  • Making maps with Python

    by Zain Memon

    Python makes it easy to store, query, and transform geodata. We will run through a handful of useful GIS libraries and patterns that let you do magical things with your maps. If you want to make maps that are more interactive and more interesting, this talk is for you.

    This talk will demystify the different parts of a usual map stack, including:

    GeoSpatial Datastores (RDBMS & NoSQL)
    Map servers (that query the geodata)
    Tile servers (that chunk the data into tiles and cache it)
    Browser UIs (and the difference between different Javascript slippy maps)

    At 2:15pm to 2:55pm, Saturday 10th March

  • Spatial data and web mapping with Python

    by Paul Smith

    Spatial data are often seen as opaque to most developers, and while dealing with them does require a shift in approach from the data types we most regularly handle, they needn’t be the domain of specialists. High-quality Python libraries and Python-based applications exist for operating on and transforming spatial data, and for creating visualizations, including maps for presentation on the web.

    This talk will be an overview of the Python libraries and applications available for handling spatial and geospatial data and creating maps for the web. It will cover libraries for open and transforming spatial data formats and representations, spatial operators and predicates for queries and relationships, spatial indexes for efficient queries, and compositing and rendering map tiles, as well as desktop applications extensible with Python that replace much of the functionality of "enterprise" GIS software.

    At 4:00pm to 4:55pm, Saturday 10th March

    In E3, Santa Clara Convention Center
