16 events & 1200 people later, the 2014 LocationTech Tour wraps up in Washington D.C. with an evening of good food, drinks, and short presentations.
The menu will feature delectable assortment of cheeses, fresh veggies, hummus, smoked salmon, glazed meatballs, herb stuffed mushrooms, and more. It will be accompanied by a choice of beers and wines.
Presentations include the following:
Managing versions of Government data with GeoGig
by Josh Campbell, Vice President of Product Management, Boundless
Versio is a distributed version control system for spatial data built on GeoGig (formerly GeoGit). Unlike solutions that rely on exchanging files or syncing to a central database, Versio provides tools that enable teams to collaborate and edit simultaneously while tracking and visualizing every change made to data and controlling which changes are accepted. Applications of Versio to government open data initiatives, particularly leveraging crowdsourcing for direct citizen input, and cross-jurisdictional collaboration will be discussed.
Geospatial Visualization for Mobile
by Steve Gifford, Consultant, Mousebird Consulting
Geospatial mobile apps are known for being practical. Maps, mostly. But data visualization can be fun or even beautiful. There's some great geospatial data display on the web. What about mobile?
Developers are doing great things with the open source WhirlyGlobe-Maply toolkit for iOS and Android. From professionals to students, there are a wide variety of cool, gorgeous, and even practical apps out there. We'll show you a selection of our favorites, discuss who uses them, and talk about the data they depend on.
Open source, open standards and 50 lines of code: A look behind GitHub’s GeoJSON rendering and diffing
by Ben Balter, Government Evangelist, Github
Last June, GitHub announced support for GeoJSON rendering — just commit and you have a versioned, open-source map. Six months later, visual GeoJSON diffing followed suit. Since then, GitHub hosts hundreds of thousands of GeoJSON files, has served millions of maps, and has diffed tens of thousands of changes, both proposed and realized. Why GeoJSON? Why Leaflet? Why openstreetmap? We’ll take a look at both the technical how, and the philosophical why, and pull back the curtain on GitHub’s recent venture into the world of GIS.
Distributed tile processing with GeoTrellis and Spark
by Rob Emanuele, Software Engineer, Azavea
GeoTrellis is a library and platform for doing high performance geospatial processing in Scala. This past year developers of GeoTrellis have created extensions to the Spark cluster computing platform to ingest raster data into a tile scheme stored in Accumulo. Spark and GeoTrellis can then be used to process and serve that data through web services to create TMS tile layers that can be used on web maps.
In this talk I'll describe the process of using GeoTrellis to ingest a number of layers at the US-national scale into a multi-node cluster, and producing responsive web services that perform computations on the tiles of those layers and serve out the resulting tiles.
Turning a Thousand or so Words into a Map
by Charlie Greenbacker, TBD
Back in September, the CLAVIN developer community shipped its second major release of the world's leading open source geoparsing software. CLAVIN intelligently extracts & resolves location names from unstructured text, allowing users to automatically generate maps from documents. This presentation will briefly review the most significant changes in this latest version, and also showcase a few of the most interesting open source projects using CLAVIN, such as the Lumify big data analysis & visualization platform and CLIFF from the MIT Center for Civic Media.
