My colleague Joel Myhre recently pointed me to Geosemble’s GeoXray platform, which “automatically filters content to your geographic area of interest and to your keywords of interest to provide you with timely, relevant information that enables you and your organization to make better decisions faster.” While I haven’t tested the platform, it seems similar to what Geofeedia offers.
Perhaps the main difference, beyond user-interface and maybe ease-of-use, is that GeoXray pulls in both external public content (from Twitter, Facebook, Blogs, News, PDFs, etc.) and internal sources such as private databases, documents etc. The platform allows users to search content by keyword, location and time. GeoXray also works off the Google Earth Engine, which enables visual-ization from different angles. The tool can also pull in content from Wikimapia and allows users to tag mapped content according to perceived veracity. One of the strengths of the platform appears to be the tool’s automated geo-location feature. For more on GeoXray:

Thanks for this informative article, it makes some very good points which I hope will help folks in the Humanitarian and Crisis Warning fields.
To clarify one point above, one major differentiator between GeoXray and a number of other systems is that typically, most systems will map locations in text only if they already have geotags – lattitude and longitude – associated with a place name. The problem is, most people don’t put in that information when they tweet, blog, or write news and other textual documents. As a result, untagged documents would be missed by these systems.
GeoXray is different in that the text doesn’t need to be pre-tagged, that’s a part of what GeoXray does. The system automatically identifies unstructured and untagged location information as part of a general text indexing that brings in a host of information – street names, government buildings, parks, names of companies, phone numbers or even people – and uses that information to match the most relevant location for a place.
Next, and of more significant, GeoXray is then able to let users filter information about places, including regions, cities or parts of cities, by topic or phrases, and have that information delivered as an alert. This allows people to follow very specific topic information about precise geographic locations of interest.
In July 2012 Geosemble was acquired by TerraGo Technologies and GeoXray is now supported on East and West Coast and UK/Middle East by TerraGo Technologies. See more here:
Many thanks for your very informative comment, Andre.
