Hipparchus, (the ancient Greek), invented latitudes and longitudes and was the first to measure distances in terms of angles.
Hipparchus, (our product), was an "open" GIS toolkit that enabled software developers to incorporate geography into their applications. And yes, we too measured distances with angles, but not using the familiar latitudes and longitudes. Instead, we work with direction cosines. And from that true "paradigm shift" flows an unexpected mathematical power and significant performance gain.
Use of the Hipparchus Library of C language functions has permitted the C/C++ language developer to deal with the "where" of things, without requiring proprietary database management systems (DBMS's) or specific graphical user interfaces (GUI's).
Firmly grounded in the science of geodesy, Hipparchus combines the speed and precision of 3D ellipsoidal vector algebra with a novel spatial indexing scheme to provide seamless and lightning-fast geographic functionality.

Curious about the academic interest in spatial indexing for global geographic
data? Then have a look at the program and proceedings of a comparatively
recent UCSB National Center for Geographic Information and Analysis International
Conference on Discrete Global Grids. In particular, see the two
contributions of our Chief Scientist, Hrvoje Lukatela.

updated downloadable public-domain cryptographic
offerings. They are exceptionally well suited to the protection of
geographic data.
Hipparchus has been in general use for more than eighteen years. More than 200 customer/developers in 27 countries have been using Hipparchus to address the geographic aspect of their applications.
It should be noted that Geodyssey developed the Hipparchus Technology and brought it to market without the financial support of any government or academic agency.
