Using open source tools including Mapbox, CartoDB, and QGIS, civic hackers are building a complete reference of all parking rules in Philadelphia. With four city and state agencies responsible for street signage, it is a more complicated task than you'd think - but help has come from surprising sources. The resulting web application, which we're hoping to begin testing in 2015, will be Parkadelphia.org.
Open Geo Data
In this tutorial, attendees will learn how they can geoprocess and analyze spatial data using Python and how it compares to other available options such as desktop GIS options (ArcMap or QGIS) or R. The hands-on tutorials will explore two interesting Python projects (PySAL and Rasterio), and give attendees the head-start needed to move forward for independent exploration and learning of more advanced geoprocessing skills using Python.
Attendees will learn about geoprocessing, analyzing and visualizing spatial data using Python and how it compares to other available options such as desktop GIS options (ArcMap or QGIS) or R. The talk will introduce various Python projects such as PySAL, GeoPandas, and Rasterio, and give attendees a starting place for independently exploring and learning geoprocessing skills using Python.
You can't make a map without data. A wealth of free and publicly-accessible geospatial data exists on thousands of independent websites scattered around the world, but tracking down these websites can be a challenge. Geolode is a collaborative catalog of open geodata websites around the world, searchable and browseable by location, topic, and other tags, so that searchers can quickly focus on the most relevant websites for their geodata needs. An open API also provides access to the catalog's records in JSON format.
New developments in mapping technology, access to geospatial platforms and data, and methods for data visualization have redefined who and what are being mapped. While maps are being produced and consumed faster than ever before, our very understanding of what defines a map has slowly drifted from what technology actually enables. The "map" still holds a strong conceptual link to the foldable paper maps popular in the past centuries. However, the nature of the map today is defined by data that changes before our eyes and information that wont be the same from one viewer to the next.
After Typhoon Haiyan the American Red Cross conducted an assessment and ground truthing of OpenStreetMap data, the results we not great. One of the key findings was the need for a tool to improve both the quality of the original data and ground truth teams ability to rapidly gather data in the critical hours after a disaster. Working with USAID the Red Cross has developed this tool. Built on OpenDataKit and other FOSS components the app allows users to build and answer survey questions about OpenStreetMap objects.
Civic data published by public agencies serves as a valuable asset enabling access to information that may have been previously unavailable, unobtainable or costly. The role of open, publicly accessible data is multi-faceted. This liberated data improves the transparency of government operations and encourages economic and community development by empowering the public to use data as a resource. Additionally, open data can start a dialog between the government and its community which results in the opportunity for important civic collaboration.
In 2010, Stamen received a Knight News Grant that led to the publication of our popular and free-to-use Toner, Terrain, and Watercolor maps using OpenStreetMap and Natural Earth data.
In 2014, we received a second grant to continue that work, expanding Terrain to cover the whole world (using open data and documenting the process), migrating to more scalable cloud-based infrastructure, and teaching the public how to do it themselves along the way.
Finding data for research or coursework can be one of the most time intensive tasks for a scholar or student. Stanford University Libraries has led development on GeoBlacklight, an open source, multi-institutional software project focused on solving these common challenges at institutions across the world. GeoBlacklight prioritizes user experience, integrates with many GIS tools, and streamlines the use and organization of geospatial data. This session will provide an introduction to the software, demonstrate current functionality, and provide a road map for future work.
