This Hootenanny Is All About Crowdsourced Mapping

[SatNews] The National Geospatial-Intelligence Agency and DigitalGlobe (NYSE: DGI) have partnered to release an open source software toolkit designed to harness the power of crowdsourced mapping for Geospatial Big Data Analytics.

The open source project Hootenanny provides a scalable processing engine and interactive editing interface to enable rapid conflation of map features generated from satellite imagery, UAVs, and mobile devices. In less than a decade, crowdsourced mapping communities such as 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.

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).

Executive Comments

“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.”

Hootenanny is available at: https://github.com/ngageoint/hootenanny. The software use, modification, and distribution rights are stipulated within the General Public License (GPL). DigitalGlobe and NGA will be hosting a Hootenanny MeetUp at the Washington D.C. Convention Center on Wednesday, June 24th, from 2:00 p.m. to 3:30 p.m. ET in Room 143A.
