Since most geoblogs are silent due to the U.S. Thanksgiving celebration, here's the latest Directions Magazine articles I wasn't able to share previously: here's links to their deCarta developers conference (devCON07) coverage, an article on the U.S. National Geospatial-Intelligence Agency and their commercial imagery strategy focused on the end-user, a short summary on the International Committee on Global Navigation Satellite Systems, another article on CityGML which is quite informative, an article on GPS-enabled device adoption driven by consumer awareness, a minimal CTIA conference coverage (CTIA is the international association for the wireless telecommunications industry) and equally short comments on the GEOINT 2007 conference.

CityGML: An Open Standard for 3D City Models
[+]
Directions Mag has an interesting article about CityGML, an open standard for 3D city models. From the article: "As Google and Microsoft clearly understand, there is a latent demand for 3D visualization of cities. But visualization is just the tip of the iceberg. Many other applications would also benefit. [...] CityGML is a common information model for representing 3D urban objects. It defines classes and relations for the most relevant topographic objects in cities and regional models with respect to their geometric, topological, semantic and appearance properties. [...] For example, graphic rendering of data encoded in CityGML can be accomplished using standardized computer graphics data formats like VRML, GeoVRML, X3D or Universal 3D (U3D)."
U.S. National Geospatial-Intelligence Agency’s Standards
[+]
The Earth is Square blog discuss a pdf regarding the U.S. National Geospatial-Intelligence Agency’s standards. From the blog: "One thing you will notice that is absent from this document: Google Earth's KML. They want to use open standards and WMS, WFS and GML are in." From the pdf: "The Center was specifically designed to
develop and coordinate data standards
with other Department of Defense
(DoD) agencies, other intelligence
agencies, civil agencies, private industry,
and foreign partners. Since its inception,
the NCGIS has charted the course
for the Nation’s geospatial intelligence
(GEOINT) standards, and today, in
2006, the benefits of that work are being
realized."
BIM: Building Information Modeling 1 comment
[+]
I just learned about Building Information Modeling last week at GeoTec 2007, including talks from the OGC and about CityGML. The CAD-GIS Interoperability shares his account of the U.S. National BIM conference while Vector One shares his view on BIM and GIS. From Vector One: "When I consider BIM, I think of it not solely in terms of one structure, but also inclusive of the ’space’ around and interacting with a given structure. Those questions I might ask of CAD system during the design, operation and management of a structure are only part of a larger geospatial equation, one including GIS. Why? Because GIS are capable of analyzing the relationships of space and features independently or collectively, together."
