This application allows visually restore a cyclorama from a set of photos covering 360 degrees in all directions to horizon. It was specially designed to restore panoramas obtained by Apollo missions in 1969-1972 but it can be used to restore any cyclorama from photos got in your tourist trip (for example). The main principle of the program is in projecting photos on a 360x360 sphere and combining it together. If you select a correct field of view (FOV) for photo images, its combination become...

NOTE: as of April 24, 2015, libsharp development has moved to Github (https://github.com/dagss/libsharp). Libsharp is a collection of algorithms for efficient conversion between maps on the sphere and their spherical harmonic coefficients. It supports a wide range of pixelisations (including HEALPix, GLESP, and ECP). This library is a successor of libpsht (http://sourceforge.net/projects/libpsht). A scientific overview over the functionality is given in the paper available at http...

A routine for converting GALPROP-generated HealPix skymaps to a compatible format which can be plotted by Aladin (v7), available from CDS at http://aladin.u-strasbg.fr. This allows free rotation of the sphere, avoiding the distortions of Aitoff and other projections often used. It is a very practical way to view and prepare skymap plots of GALPROP output. GALPROP outputs a spectrum per HealPix pixel, while Aladin requires each energy to be stored as a column. A conversion is required to make...

Libpsht is a collection of algorithms for efficient conversion between maps on the sphere and their spherical harmonic coefficients.

ruby-sphere is a set of libraries and user interfaces written in Ruby to calculate apparent positions of stars with a moderate accuracy. Its goal is to provide an easy way to plan astronomical observations.

I can not find a simple graphical rutin to draw a geographic sphere with geo-coordinate grid on the Canvas. I need to move , rotete this globe and change the eye point. And an other function to get a geographic coordinates from mouse position.
