53Cheetham, RobertAzavea develops open source tools for geospatial data analysis. We are trying to enable the transformation of geographic data into new forms, rather than simply displaying it on a map. We want to make it easier for people to do magical things with spatial data. Robert Cheetham will describe some of the major challenges to contemporary spatial data processing and introduce the LocationTech projects aimed at addressing these challenges, including GeoTrellis, GeoMesa, and GeoJinni.

3Clark, ScottThe The Rapid Open Geospatial User-Driven Enterprise (ROGUE) Joint Capability Technology Demonstration (JCTD) is focused on supporting humanitarian assistance and disaster response efforts in the SOUTHCOM area of responsibility. ROGUE is addressing some of the core challenges in the geospatial community right now -- distributed collaboration, disconnected editing workflows, and provenance of data. All of this is being delivered as open source software, and based on open standards to encourage adoption by partners. This talk will explore how the ROGUE team is using GeoNode, GeoGit, and the OpenGeo Suite to provide a collaborative editing environment that maintains provenance of the data. In addition to developing GeoGit, the ROGUE technical team has demonstrated practical application of the technology through mobile and web applications (Arbiter & MapLoom). Both of these projects are available as open source as well. The discussion will include an overview of how the technology is being used operationally in Honduras and for risk assessment and response. A short demo will wrap up the talk.

62Greenbacker, Charlie et al.Lumify is an open source big data integration, analytics, and visualization platform designed to help users discover connections and explore relationships in their data. It can ingest anything from spreadsheets and text documents, to images and video, representing this diverse data as a collection of entities, properties, and relationships between entities. Everything is stored in a scalable and secure graph database to enable advanced social network analysis and complex graph traversals. Built on proven open source technologies for big data like Hadoop, Storm, and Accumulo, Lumify supports a variety of mission-critical use cases centered around the emerging concepts of activity-based intelligence (ABI), object-based production (OBP), and human geography (HG). Its intuitive web-based user interface provides a suite of analytic options with multiple views on the data, including 2D and 3D graphs, full-text faceted search, histograms with aggregate statistics, and an interactive geographic map exploration feature. This talk will demonstrate how Lumify can be used to fuse structured and unstructured data from multiple sources into a unified knowledge base, and then analyze that knowledge to uncover hidden connections and actionable insights buried within the data's geospatial context.

179Fox, AnthonyThe 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. 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.

19Pomfret, KevinThis presentation by Kevin Pomfret from the Center for Spatial Law and Policy will identify the main components of a license agreement and discuss how each component applies to geospatial data. It will also highlight some of the unique issues associated with the licensing of geospatial data, such as copyright and privacy. The presentation was developed for non-lawyers, so it will have minimal legal jargon.

36Devasundaram, Jayanth et al.Public health entities around the world do not have the Information Technology (IT) resources and infrastructure necessary for building robust applications for disease surveillance. Using the open-source model and cloud computing infrastructure, an attempt has been made to enable global reporting of some of the parameters around birth defects and potential "causative" environmental factors on a spatial basis. The application includes elements of peer review of reports and preservation of confidentiality of the patients and reporters in novel ways. Spatial aggregation of patient location data provides a summary of occurrence of birth defects worldwide or limited to a region depending on the requirements of the end-user(s)Spatial navigational tools enable the user to drill down to an aggregation level of 1 x 1 degrees square. Peer review and requests for detailed data from data owners occur through search tools and an email interface.

26Kunce, DaleThe American Red Cross leverages open data in many ways for long term programs and during disaster responses. Most recently during Typhoon Haiyan in the Philippines thousands of volunteer mappers made millions of edits to OpenStreetMap in the affected areas of the Philippines to support humanitarians such as the Red Cross on the ground. This session will look at the mechanics of how the American Red Cross uses the great work of digital volunteers to empower its relief teams on the ground to navigate, plan, and make life changing decisions.

21Turner, AndrewGovernment agencies are responsible for managing updated and authoritative as part of their operations. Recently open government¹ has become a popular movement that promises transparency, engagement, and efficiency for agencies and citizens. Increasingly open government mandates are also requiring organizations to make their data freely available through the web. GIS is already at the heart of the majority of data management in government and also accounts for most of the open data that is intended for release. ArcGIS Open Data leverages your existing infrastructure to make your data discoverable, explorable, and accessible without any migration or additional workload. By aligning government open data to existing workflows as well as the architecture of the web, it's possible to readily fulfill these mandates and achieve agency vision.

18Cheetham, RobertGeoTrellis is a high performance geoprocessing engine and programming toolkit. The goal of the project is to transform user interaction with geospatial data by bringing the power of geospatial analysis to real time, interactive web applications. GeoTrellis was designed to solve three core problems, with a focus on raster processing: Creating scalable, high performance geoprocessing web services Creating distributed geoprocessing services that can act on large data sets Parallelizing geoprocessing operations to take full advantage of multi-core architecture Features: GeoTrellis is designed to help a developer create simple, standard REST services that return the results of geoprocessing models. Like an RDBS that can optimize queries, GeoTrellis will automatically parallelize and optimize your geoprocessing models where possible. In the spirit of the object-functional style of Scala, it is easy to both create new operations and compose new operations with existing operations.

10Marin, JuanEveryone working with geospatial data eventually faces the problem of managing their 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. In this 2 hour workshop, we'll walk through core procedures in managing version history and inter-operating with preexisting spatial software tools.
