In less than a decade crowdsourced mapping communities like OpenStreetMap™ have attracted over 2.5 million volunteers who have digitized more than 130 million buildings and 1.3 million miles of roads. Countless other organizations and individuals are using satellite imagery and other methods to capture the geometry and metadata of roads, buildings, and points of interest. To create high-quality maps and enable analytic functions like routing, suitability analysis, or predictive modeling it is important to unify multiple sources to create the best available database.
“The commercialization of GEOINT is leading to exponential growth of publicly available geospatial information,” said Chris Rasmussen, NGA’s public software development lead. “Hootenanny as an open source project will enable new levels of data sharing across the community that will increase our nation’s ability to quickly respond to emerging threats. This is a pro-active move that steers into the collaborative mapping environment to derive more value from unclassified sources.”
Hootenanny leverages the open architecture of OpenStreetMap™ to facilitate integration of diverse geospatial datasets into a common key value data structure. An open library of conflation algorithms applies various techniques to unify the geometry and metadata of topographic features. Conflicts can be visualized and resolved through an interactive application built on the iD Editor, an open source map editing tool developed by Mapbox. Conflated datasets can be exported in a variety of GIS formats including ESRI Shapefile, File Geodatabase, Web Feature Service, and native OpenStreetMap™ formats. Hootenanny also enables Geospatial Extract Transform Load (ETL) capabilities supporting various schemas such as Topographic Data Store (TDS), and Multi-National Geospatial Co-Production Program (MGCP).
“DigitalGlobe is rapidly evolving our business beyond satellite imagery into the world of Geospatial Big Data,” said Tony Frazier, SVP U.S. Government Solutions at DigitalGlobe. “Our human geography product contains over 1.6 million POIs aggregated across 1,500 unique sources. Hootenanny will help us more effectively fuse the data we extract from our imagery with other sources of publically available information.”
