fitsmap 0.1.2

Turn fits files/catalogs into a leafletjs map

FitsMap

FitsMap is a tool for displaying astronomical images and their associated catalogs, powered by LeafletJS.

Survey images can have dimensions in the tens of thousands pixels in multiple bands. Examining images of this size can be difficult especially in multiple bands. Memory constraints and highly specialized tools like DS9 make analysis infeasible or cumbersome. FitsMap addresses these two issues by converting large fits files and images into tiles that can be presented using LeafletJS. Another issue in examining survey images is examining a catalog of sources in the context of the images. FitsMap addresses this by converting a catalog of sources into JSON map markers, which can be viewed in the webpage. Additionally these sources are searchable using by the web interface by the column id.
