SOCET SET v5.5.0 supports new Earth Gravitational Model 2008
The Earth Gravitational Model 2008 (EGM2008), developed by the National Geospatial-Intelligence Agency (NGA), has been released. The model provides worldwide coverage of gravity data at 5’x5′ mean resolution with geoid accuracy of 15cm.
EGM2008 is constructed from a combination of GRACE satellite data, topographic data, altimetry on sea, and gravity observations on land areas. EGM2008 is developed up to degree/order 2160 with some additional terms up to degree/order 2190.The EGM2008 model coefficients and related products are freely available from the following Web site:

SOCET SET v5.5.0 supports the EGM2008 model using USG supplied grids of pre-computed geoid undulations at 1×1-minute resolution. The grid files translated into SOCET SET terrain file format are available for download from the GXP FTP site. Please contact your GXP customer support representative for instructions.
GXP Xplorer Desktop product
GXP Xplorer is a new BAE Systems software data library that makes it easy to find and share geospatial data on a local network and across an enterprise.
The product is ideal for users in work groups who are searching for images, terrain, features, videos, documents, and other files. It is a SOCET GXP add-on module, and also is available as a stand-alone application. GXP Xplorer is the replacement for GXP’s legacy Visual Coverage Tool (VCT).
Released in June, GXP Xplorer v1.0 includes capabilities for cataloging, sharing, and delivering geotagged images in NITF, GeoTIFF, and TFRD formats; and indexes text and formats such as Word documents, PowerPoint presentations, video, JPEG, and any other types of files. GXP Xplorer v1.0 enhances collaboration by allowing users to perform federated searches of multiple GXP Xplorer catalogs. It creates GeoRSS feeds and KML formats and sends data to SOCET GXP, Google Earth, ArcGIS Explorer, and PowerPoint.
GXP Xplorer v2.0 is scheduled for release at the end of the year along with SOCET GXP v3.2. It expands on these capabilities to catalog and deliver more geospatial products, including CADRG, ADRG, CIB*, DTED, SRTM, and DPPDB*. Geotagged video support will be added so that MPEG2, MPEG4, and AVI files can be discovered and cataloged using areas of interest on the map.
New delivery options also are planned for GXP Xplorer v2.0. Users will have the option to receive selected data as JPIP, which is a JPEG2000 compressed-stream format useful for low-bandwidth connections — only the data of interest is streamed into a viewer, versus downloading the entire file. Users can order raw or orthorectified images. Terrain and ortho Web processing services will be added to the GXP Xplorer catalog Web services process for orthorectification.
GXP Xplorer v2.0 features in development are designed to save users time and manual steps:
• A subscription option lets users subscribe to an area of interest and specify data requirements, such as cloud cover percentage or certain product formats, and receive downloads automatically as soon as data meeting their subscription criteria becomes available.
• A connector to data sources can be queried via the NATO Standard Image Library Interface — STANAG 4559.This interface is an implementation profile of the Geospatial and Imagery Access Services Specification. To save time, the GXP Xplorer Connector allows permitted users to search many existing libraries in a single search, rather than searching each source individually.
GXP Xplorer v2.0 will be available on Solaris x86 platform, Microsoft Windows XP, Windows 7, and Windows Server platforms of GXP Xplorer v1.0.
