PYXIS for the GeoWeb

Spatial data value is locked up, unable to be released due to the inability to do massive on-the-fly geospatial integration. Historic approaches to geospatial information integration cannot meet this growing expectation for general on-demand net-centric access to the rich and diverse knowledge that is held worldwide.

PYXIS provides a necessary solution to have a Geospatial-Web – a digital Earth where anyone can complete the geospatial search “What is here?”. The key is the PYXIS innovation: a Digital Earth Reference Model encompassing principals of a digital model:

• A discrete uniform partitioning (a tessellation or tiling of cells over the Earth surface);
• A unique linear non floating point index for each discrete cell that encompasses within the index both a parent child hierarchical relationship and a coordinate system that converges to the set of all real numbers;
• A set of mathematical relationships built on the index: algebra, geometry, Boolean operations, image processing, etc; and
• A strategy for quantizing values, preferable integers, to each discrete cell.
