Geosemble Technologies and MDA Information Systems, Inc. (MDA) have announced an initiative to integrate two of their respective products in order to provide enhanced situational awareness for a range of government and commercial users of satellite imagery and maps.
The MDA product, known as Persistent Change Monitoring (PCM), provides a process for detecting changes over time for features in satellite imagery. The change indicators can be used as a cuing tool for intelligence analysis by identifying new permanent features such as roads, tunnels, and other structures of interest. These features can then be confirmed with high resolution data.
Geosemble Technologies’ product, known as GeoXray, is a geospatial monitoring system in which locations on the earth are monitored for mentions across vast feeds of data coming from news, blogs and social media such as Facebook, Twitter and YouTube. The system employs a sophisticated text-matching algorithm that accurately links content to places down to the building level, without the need for addresses, latitude/longitude or in some cases even the name of a city. Users of GeoXray can adjust the area of interest in real time - either by enlarging or shrinking the area of interest, or by moving to another area - and get a correspondingly different read-out of content for that area. Further, users can superimpose filters on the content returned for a given area to restrict information to only their topic of interest. Users can then set alerts for desktop and mobile devices.
Working together, PCM and GeoXray complement each other in that many of the users of satellite imagery and maps experience inefficiencies in both areas that PCM and GeoXray address – namely, time consuming research and analysis to achieve current understanding of physical features for an area as well as the “human geography” of an area as revealed by associated information from social media and other sources.
Noted Greg Koeln, President of MDA Information Systems, Inc., “By integrating these technologies we are able to move more time-consuming search work to specialized software so we can save our human assets for the complex reasoning and analysis at which they excel,” he said.
Commented Geosemble CEO Andre Doumitt, “It’s a bit like building a house,” he said. “We don’t need analysts sawing through trees as part of that process; we can give them powerful tools for that. Where they shine is in building up a complex and sturdy product, and we want to help them spend more time doing that,” he said.
Persistent Change Monitoring uses medium resolution multispectral satellite imagery such as Landsat, Spot, or RapidEye to cost-effectively locate indications of land change over large areas. Analysts then use high resolution imagery from aerial photos or commercial satellites such as GeoEye and DigitalGlobe to characterize the changed areas and update various geospatial data bases. A key to a most efficient change detection product is minimizing false change indicators. Most change detection algorithms detect so much seasonal vegetation and crop change, that the real feature change is obscured. In contrast, PCM removes a great deal of false change by using multiple imagery dates to filter out seasonal false indicators. PCM relies on the fact that transient vegetation such as agriculture and forests keep changing, but features such as a new road or housing development persist.
GeoXray™ is a software product that spatially enables unstructured text from the internet and other sources so that viewers can geographically “see” what’s related to a particular area of interest, either in a map view or as a list of textual content. Integrating news, blogs, tweets, Youtube and an organizations proprietary data, the system gives users a “triple filter” of sorting by location, by topic and by time so that users can start with a place they care about and learn about things they’re interested in. The output of GeoXray can be viewed in its own native GeoXray viewer or tapped via an API and displayed on a variety of systems.
Founded in 2004, Geosemble Technologies helps organizations visualize relevant data geographically. The company’s flagship product, GeoXray™, links unstructured content to locations. Its MapStrata product extracts raster map data and automatically overlays and aligns it on aerial imagery. Uses for the technology include Government and Military programs, municipal redevelopment, Business Intelligence, Enterprise Search, and geographic content delivery for mobile phone users. The company is an In-Q-Tel portfolio company, a strategic Google® Earth Enterprise Partner, and a developer in the Oracle® PartnerNetwork, and a DARPA SBIR Phase II contractor. Geosemble Technologies, Inc. is privately held. Learn more at http://www.geosemble.com.
