OpenWebGlobe is a project and technology for processing and interactively visualizing vast volumes of geospatial data in a 3d virtual globe.The OpenWebGlobe virtual globe can have several data categories like image data, elevation data, points of interest, vector data, and 3D objects. Before streaming such massive and complex data over the internet, this data must be pre-processed. Such pre-processing usually comprises a transformation from a local to a global reference system, creation of pyramid layers or levels of detail (LOD), tiling of the data, and optionally compression and encryption. Recently, these algorithms were ported to high performance compute cluster using OpenMP and MPI and are also released as open-source. Because data sets are usually large, containing several terabyte
