Mizar, a GIS web application for planets and the celestial sphere

Mizar is an open-source, WebGL-based JavaScript library for visualizing rasters and vectors on celestial bodies models : planets and the celestial sphere. This library, developed since 2013 by CNES, has been used in several fields (climate monitoring, hydrological projects, exploration of Mars and the Moon, astrophysics/cosmology). These various implementations allowed the library to integrate new functionalities and to evolve its architecture. Currently, this library has been successfully integrated with CNES 'latest archiving system tool (REGARDS), which will allow Mizar to have a stable budget for development and maintainability.

The main advantage of this library is to provide high 3D performance for the discovery and visualization of geospatial data for the celestial sphere and planets via the same API, thus facilitating the learning costs for a developer. The 3D performance and fluidity of the animation are provided by the WebGL technology that allows the use of the GPU unlike the 2D canvas. MIZAR also implements a set of protocols from the IVOA / OGC worlds. Moreover, because of the architecture of MIZAR, it is quite simple to add new protocols to the library.

Finally, we will also discuss issues related to IVOA / OGC standards and tentative convergence.
