Large Catalogue Query Performance in Relational Databases

Robert A. Power
2007 Publications Astronomical Society of Australia  
Most of the general queries perform adequately when appropriate indexes are present in the database.  ...  Neighbour finding and cross matching are not well supported in a database environment when compared to software specifically developed to solve these problems.  ...  This investigation was undertaken as partial fulfillment of the requirements for the Graduate Diploma in Science at the Australian National University supervised by Dr. Paul Francis.  ...

Octahedron-Based Projections as Intermediate Representations for Computer Imaging: TOAST, TEA and More [article]

Thomas McGlynn, Philip Rosenfield Microsoft Research,
2018 arXiv   pre-print
This paper defines and discusses a set of rectangular all-sky projections which have no singular points, notably the Tesselated Octahedral Adaptive Spherical Transformation (or TOAST) developed initially  ...  TOAST is strongly related to the Hierarchical Triangular Mesh (HTM) pixelization and is particularly well adapted to the situations where one wishes to traverse a hierarchy of increasing resolution images  ...  Rather it uses a hierarchical transformation identical to those of the Hierarchical Triangular Mesh (HTM) pixelization popularized by the Sloan Digital Sky Survey (see Kunszt et al. 2001; Kazhdan et al  ...
