Durable geospatial data and the budding open-source ecosystem driving it

Too often geospatial data is treated in an ephemeral manner. Its metadata is missing, it is hard to find, and usually it is not preserved. Stanford University Libraries presents an approach for preservation, access, and discovery of geospatial data and maps in a digital repository. This community approach uses a sustainable, collaborative ecosystem of existing open-source software projects and standards, while also developing new FOSS4G tools to fill gaps. These new tools include GeoBlacklight and OpenGeoMetadata. Presented topics will include an overview of geospatial data in a digital repository, an introduction to the tools that make it possible, a live demonstration, and discussion about the role of libraries and repositories within the FOSS4G community.

Global Forest Watch: Using Open Data to Save the World’s Forests

Global Forest Watch (GFW) is an interactive online forest monitoring platform designed to empower people everywhere with the information they need to better manage and conserve forest landscapes. Thanks to open data, GFW is able to do the following: Monitor when and where forests are changing. NASA’s freely available Landsat and MODIS data has allowed hundreds of scientists and researchers to develop innovative solutions to monitor landscape changes. Algorithms are now used to process and analyze this remotely-sensed data to show when and where forests are changing with surprising precision and speed. Understand why forests are changing. Open data showing boundaries of land allocated for specific purposes, such as commodity production and conservation, as well as land management, allows us to understand why forests are changing. Are trees being cleared for palm oil? Are certain swaths of forests still standing because they are managed by indigenous groups? Gauge the significance of deforestation. Additional open data provided by research institutions, governments, and others is used to understand the implications of deforestation on biodiversity, climate change, and provision of ecosystem services. For example, was a recently clear-cut area of forest home to endangered species? Was it a carbon rich primary forest? Spark further innovation. GFW’s open-source code and APIs allow others to leverage GFW’s analysis tools and open data to create additional forest monitoring and management tools.

OSGeo conference videos as a resource for scientific research: The TIB|AV Portal

This paper reports on new opportunities for research and education in Free and Open Source Geoinformatics as a translational part of Open Science, enabled the growing collection of OSGeo conference video recordings at the German National Library of Science and Technology (TIB). Since 2015, OSGeo conference recordings have been included to the collection sphere of TIB in information sciences. Currently, video content from selected national (FOSSGIS), regional (FOSS4G-NA) and global (FOSS4G) conferences is being actively collected. The annual growth exceeds 100 hours of new content relating to the OSGeo software projects and the OSGeo scientific-technical communities. This is seconded by retrospective acquisition of video material dating from past conferences, going back until 2002 to preserve this content, ensuring both long term availability and access. The audiovisual OSGeo-related content is provided through the TIB|AV Portal, a web-based platform for scientific audiovisual media providing state-of-the art multimedia analysis and retrieval. It implements the requirements by research libraries for reliable long term preservation. Metadata enhancement analysis provides extended search and retrieval options. Digital Object Identifiers (DOI) enable scientific citation of full videos, excerpts and still frames, use in education and also referral in social networks. This library-operated service infrastructure turns the audiovisual OSGeo-related content in a reliable source for science and education.

OSM Stats: Rewarding contributors and real-time tracking of OSM

Mapathons are an increasingly effective way to get data into OpenStreetMap. The Missing Maps project hosts mapathons to increase the amount of data in areas that don't have large local OSM communities. The American Red Cross and Development Seed have built an analytics platform that tracks user trends in real-time and rewards contributors for their efforts, as can be seen at missingmaps.org OSM-stats tracks user's activity, consistency and relative reputation, reporting detailed metrics and awarding a variety of themed badges based on the type and magnitude of contributions. Badges range from simple tasks ("Add 4 roads") to challenging ("Map in 10 countries"). Leaderboard pages display up to date detail on the most active users for a current project, while hashtag groupings display statistics to be separated out, allowing tracking of groups. A map of each users commits can be seen, as can a map view indicating the last 100 changes. Most of the contributions for the Missing Maps project occur during mapathons where hundreds of volunteers submit edits and additions over a couple of hours. This means that the system needs to handle large spikes of activity when thousands of edits are added. We deployed the OSM-stats components using AWS Lambda functions and Kinesis streams. These scale very well to meet the needs of Mapathons and incur minimal cost when not in use.

Paleomaps: SDI for paleoenvironment GIS data

Paleoenvironmental studies and according information (data) are abundantly pub-lished and available in the scientific record. However, GIS-based paleoenviron-mental information and datasets are comparably rare. Here, we present an OpenScience approach for collecting and creating GIS-based data and maps of paleoenvironments, and publishing them in a web based Spatial Data Infrastructure (SDI),for access by the archaeology and paleoenvironment communities. The Open Science approach to the publication of data, allows to properly cite the publisheddatasets as bibliographic sources in research that builds upon these data sets.This paper has its focus on the implementation and setup of the Free and OpenSource Software for Geospatial (FOSS4G) based SDI, and on the workflow forcompiling and publishing the GIS data.

Routing for Driving Pleasure

Americans have miles and miles of open highways. Set the cruise and drive for hours in straight lines. Routing a user to find the fastest way from an origin to a destination is performed by any number of providers. But what if you're not interested in the shortest route? What if you're looking for the most scenic route? The most entertaining? This is a problem for planners of regularity rallies. Planners hope to provide challenging roads at legal speeds that avoid heavily residential and developed areas. OpenStreetMap, PostGIS, QGIS, and pgRouting to the rescue! Learn how to create alternative routing-cost structures to find and create new types of routes. An affinity for routing, driving, and/or gravel roads a plus. Dan "Ducky" Little (dbSpatial LLC)

Using Open Source Tools to Visualize Spatial Activity Drone Restrictions

Drone service providers are currently spending a lot of time on researching which permissions they need to fly their drones over a certain area. Today, most governmental regulations forbid to operate drones nearby transportation infrastructures or urban environments. In our talk we present a web application build based on open source tools to visualize such geographically-bound activity restrictions and therefore ease the process for drone service providers. The resulting system makes it possible for drone service providers to draw a flight path and receive immediate feedback on which permissions they will need to fly their drones in a specific area. A user is also enabled to edit the flight path to omit certain features and view live changes on the map and the instruction list. The project is implemented using a PostGIS database to store the space usage rules (SURs) (in our case the drone regulation of a specific country). A potential flight path drawn in an OpenLayers map by the user is send to the back-end which returns the regulations enforced in that area. In the front–end WFS-requests are performed to check whether the SURs apply to the specified flight path (i.e. when one or more features triggering certain rules are close enough to the flight path). Geoserver is used to create these WFS’s, the geometries of the features are extracted from OpenStreetMap. All instructions for the flight path are visualized in an instruction list linked to the maps highlighting the features in OpenLayers and in Cesium.

Optimizing Last mile Vaccine Supply Chain in Northern Nigeria using FOSS4G Solutions

In 2012, the Federal Government of Nigeria launched the Saving One Million Lives Initiative aimed at expanding routine immunization to 87% coverage that will protect over 6 million children against vaccine preventable diseases such as measles, meningitis, polio, tetanus, hepatitis, yellow fever and tuberculosis . In 2013, the GAVI Alliance approved US 21 million to help improve vaccine supply chains . Despite several innovations and initiatives to optimize the supply chain and storage of health commodities in Nigeria, there are still known gaps in the supply chain in the health sector in Nigeria. Achieving a good coverage of routine immunization is almost impossible without the optimization of last mile delivery – especially in the hardest-to-reach places of Nigeria. Geographic Information science (GIS) techniques play a big role in the design and optimization of last mile delivery of vaccines down to Local Government Areas and health facilities in remote places. This presentation discusses how eHealth Africa has implemented FOSS4G solutions to enhance an effective vaccine delivery system in Kano State, Nigeria; the second most populated state in Nigeria using open source tools like OpenDataKit, QGIS, JOSM, OSRM. We also discuss the importance of OpenStreetMap and open data to replicating this in other countries.

Bringing benthic data to the surface - moving Marine Recorder into an open source spatial database.

The Joint Nature Conservation Committee (JNCC) is one of a number of organisations that run inshore and offshore surveys to collect data on seabed biodiversity (e.g. species records and habitat types). The main storage and collation system for these data is Marine Recorder, a Microsoft Access-based database application developed by JNCC in 2002. Despite several updates since then, the system is now significantly out of date, and the lack of internet connectivity or the ability to store spatial data is a major problem. As a result of these issues, organisations in the UK that collect benthic data are investigating more up-to-date systems and there is a significant risk of data fragmentation. JNCC are currently in the process of moving all of our spatial data from a file based system into PostGIS. This talk will describe JNCC’s open-source geospatial information strategy and how we are integrating Marine Recorder into this, discussing the efficiency savings that this provides, as well as our plans for developing a full open-source, online replacement for Marine Recorder in the future.
