Everything about Digital Earth Reference Model

The term Digital Earth Reference Model (DERM) was coined by Tim Foresman in context with a vision for an all encompassing geospatial platform as an abstract for information flow in support of Al Gore's vision for a Digital Earth. The Digital Earth reference model seeks to facilitate and promote the use of georeferenced information from multiple sources over the Internet. A digital Earth reference model defines a fixed global reference frame for the Earth using four principles of a digital system, namely:Discrete partitioning using regular or irregular cell mesh, tiling or Grid; Data acquisition using signal processing theory for assigning binary values from continuous analog or other digital sources to the discrete cell partitions; An ordering or naming of cells that can provide both unique spatial indexing and geographic location address; A set of mathematical operations built on the indexing for algebraic, geometric, Boolean and image processing transforms, etc. Wikipedia →
