“Roads are the seeds of tropical forest destruction,” said the prominent ecologist Thomas Lovejoy. But until now, roads have been difficult to map and visualize, often discovered only after they have been abandoned and the damage to the forest around them has been done.
As geographic vector datasets continue to become more commonplace and available to the public, GIS users find they routinely work with maps that can vary in format, coverage, attribute schema, completeness, and accuracy. Often times the solution is to work with parts of each dataset in order to produce a superior “best-of-breed” conflated map that leverages the best features and information from each of the individual sources.
Open source mapping tools are revolutionizing disaster preparedness and response around the world. After the Nepal Earthquake in 2015, more than 8000 contributors came together using open source tools such as the Humanitarian OpenStreetMap Team's Tasking Manager to make more than 13 million edits to OpenStreetMap in the first two weeks after the earthquake. These tools are also empowering communities and international NGOs such as the American Red Cross and Medicins Sans Frontiers to map vulnerable areas before disasters occur.
TeachOSM is an emerging resource for educators and instructors to help them integrate OpenStreetMap in their classroom and lessons. This presentation will show how TeachOSM is helping teachers use OpenStreetMap to teach basic geographic concepts and in the process, train the next generation of mappers.
The presentation will also highlight things such as TeachOSM programming initiatives and activities, Geobadges, new service-based learning opportunities for those who contribute to open mapping projects such as MapGive, MissingMaps, Humanitarian OpenStreetMap Team.
OpenStreetMap is amazing. Many of the offline tools are amazing. However, for intensive mapping by small teams, the existing tools fall short and make editing and contributing to OSM difficult. This is especially true in remote communities and parts of the developing world that lack reliable internet connectivity. Because the Red Cross’ mapping locations are so remote, we needed a better way to interact and edit OSM in a disconnected way for days and potentially weeks at a time.
This talk focuses on the dynamic costing methods applied to Valhalla, open source routing and navigation software built to use OpenStreetMap data. Rather than assigning costs to the routing graph during data import or graph creation, Valhalla performs costing at run time using a wide range of attribution. This allows flexible route generation using the same data. Costing modules exist for automobile, bus, truck, bicycle, pedestrian, and public transit.
NPMap builds tools and services to help national parks create beautiful digital maps. We use the OpenStreetMap model to create a dynamic cartographic database used to power custom National Park Service basemaps.
Our current technology backend is a PostGIS database in the OpenStreetMap schema. We use commercially supported FOSS tools from CartoDB and Mapbox to publish map products that combine official NPS data inside parks and OSM data outside of parks.
