for algebraic, geometric, Boolean and image processing transforms, etc. The Open Geospatial Consortium has a spatial reference system standard based on the DERM called a [Discrete Global Grid] System (DGGS). According to OGC "a DGGS is a spatial reference system that uses a hierarchical tessellation of cells to partition and address the globe. DGGS are characterized by the properties of their cell structure, geo-encoding, quantization strategy and associated mathematical functions. The OGC DGGS standard supports the specification of standardized DGGS infrastructures that enable the integrated analysis of very large, multi-source, multi-resolution, multi-dimensional, distributed geospatial data. Interoperability between OGC DGGS implementations is anticipated through extension interface encodings of OGC Web Services.". Thus, the DGGS is a discrete, hierarchical, information grid with an addressing (or indexing) scheme to assign unique addresses to each cell across the entire DGGS Domain. Background United States Technology developments that support the current Digital Earth technological framework can be traced to U.S. computing advances derived from the Cold War competition, the space race, and commercial innovations. Therefore, many innovations can be tracked to corporations working for the Department of Defense or NASA. However, the philosophical foundations for Digital Earth can be more closely aligned with the increased awareness of global changes and the need to better understand the concepts of sustainability for the planet's survival. These roots can be traced back to visionaries such as Buckminster Fuller who proposed development of a GeoScope half a century ago, analogous to a microscope to examine and improve our understanding of the planet Earth. From Fall 1998 until Fall 2000, NASA led the U.S. Digital Earth initiative in cooperation with its sister government agencies, including the Federal Geospatial Data Committee (FGDC). Attention to consensus development of standards, protocols and tools through cooperative test-bed initiatives was the primary process for advancement of this initiative within the government community. In 1999, NASA was selected to head a new Interagency Digital Earth Working Group (IDEW), due to its reputation for technology innovations and its focus on the study of planetary change. The new initiative was located in the NASA's Office of Earth Sciences. This titular focus was considered necessary to help align over 17 government agencies and keep sustainability and Earth oriented applications as a guiding principle for the Digital Earth enterprise. Components for development of 3-D Earth graphic-user-interfaces (GUIs) were placed into various technological sectors to stimulate cooperative development support. While initially
