This evening event in Washington D.C. has an international perspective. It is part of the LocationTech tour, a 6 city roadshow featuring the best of location aware open source technology.
There are 6 outstanding speakers presenting different technologies and use cases.
The event concludes with an invitation to join speakers and fellow participants for a drink at CIRCA (2221 I St NW #300).

OpenSource in the Classroom: From Foggy Bottom to Kathmandu
For the last few years our upper division GIS class at GW geography has integrated OpenSource, Open Street Map assignments into the course curriculum. Last year, we worked closely with the International Services Division at the American Red Cross to map disaster prone communities in two countries; Columbia and Indonesia. These efforts were in conjunction with the national red cross chapters in these countries who are using the data toward disaster mitigation efforts. This year, four geospatial classes are joining forces to map communities in and around the city of Kathmandu. Were are partnering with the Geocenter at USAID, and the Open Cities project at the World Bank, and a local non-profit, Kathmandu Living Labs. To date our students have loved this assignment, as they are contributing to real world data. My colleague Richard Hinton and I are working on formalizing the workflow we developed to assign, operate and grade this type of assignment for undergraduate classes. We are in the process of developing a small module that could be used in any undergraduate class (not just GIS or Geography) - that promotes the collective creation of open source data.

CLAVIN: an open source geoparser
As the demand for geospatial analytics continues to grow, most of human knowledge remains "trapped" in text documents. Proprietary solutions for extracting geo data from unstructured text are expensive and difficult to scale. As an alternative, CLAVIN is an award-winning open source software package for document geotagging and geoparsing that's fast, accurate, easy to use, and scales to accommodate big data using Hadoop. CLAVIN automatically extracts location names from unstructured text and intelligently resolves these names against a gazetteer to produce rich geographic data. It also handles misspellings, alternate names, and ambiguous references like "Springfield." By performing geographic entity resolution based on semantic context, and subsequently enriching unstructured text documents with structured geo data, CLAVIN powers map-based visualizations, hierarchical geographic search, and advanced geospatial analytics. This talk will describe how CLAVIN works, how it's used to unlock the geospatial potential of big data, and will include a live interactive demonstration.

GeoMesa: Scalable Geospatial Analytics on Accumulo
The proliferation of smart phones with embedded geolocation sensors has led to an explosion of geospatial data in all domains. Every mobile app now asks users to enable location services and generates copious geotagged data. Existing solutions for managing this data rely on traditional approaches using geospatial relational RDBMS platforms like PostGIS or proprietary systems. GeoMesa is an open source scalable spatio-temporal index built on top of the Accumulo distributed column family database that provides efficient OGC standards based access and query capabilities of very large datasets. GeoMesa provides WMS or WFS services over HTTP for data access as well as an API based on Geotools. Spatial analytics in GeoMesa can leverage Hadoop to perform computations in parallel on a cloud. Sensitive personal information inherent in consumer geolocated data can be protected using Accumulo's cell level security. This talk will cover the indexing structure in GeoMesa and how it enables scalable geospatial analytics in a cloud platform.

Redefining Geospatial data versioning: The GeoGit approach
Every organization working with geospatial data eventually faces the problem of managing its information and assets as they change over time. Versioning of geospatial data has been an issue for any workflow that involves more than one individual. Questions like who changed what and when become hard to answer, and while versioning approaches have existed for a while, they are cumbersome to use and utilize old paradigms. GeoGit takes concepts and lessons learned from the open source programming world and applies them to management of geospatial information, allowing better and decentralized management of versioned data and enabling new and innovative workflows for collaboration.

20:35 - Joshua S Campbell, Geographer & GIS Architect at Humanitarian Information Unit, U.S. Department of State (20 minutes) WATCH THE VIDEO
The Humanitarian Information Unit (HIU) at the U.S. Department of State has been closely tracking the Syrian humanitarian crisis since April 2012. Specifically, the HIU has been producing weekly or bi-weekly map products on the crisis using data on the number of refugees, location and status of refugee camps, areas of refugee presence, areas of conflict and displacement, and border crossings. In order to visualize this time-series data in an interactive environment, the HIU has built a web map viewer with integrated d3.js charts and custom time-slider control. Additionally a custom data management backend was built to manage and update the data. The entire application was built using only open source software and is cloud hosted. Elements of both the viewer and backend system will be demonstrated.
