| Abstract: |
As a new generation of large format, high-resolution imagers come online
(ODI, DECAM, LSST, etc.) we are
faced with the daunting prospect of
astronomical images containing upwards of hundreds of thousands of
identifiable sources. Visualizing and interacting with such large
datasets using traditional astronomical tools appears to be unfeasible,
and a new approach is required. We present here a method for the
display and analysis of arbitrarily large source datasets using
dynamically scaling levels of detail, enabling scientists to rapidly
move from large-scale spatial overviews down to the level of individual
sources and everything in-between. Based on the recognized standards of HTML5+JavaScript, we enable observers and archival users to interact
with their images and sources from any modern computer without having to
install specialized software. We demonstrate the ability to produce
large-scale source lists from the images themselves, as well as
overlaying data from publicly available source ( 2MASS, GALEX, SDSS, etc.) or user provided source lists. A high-availability cluster
of computational nodes allows us to produce these source maps on demand
and customized based on user input. User-generated source lists and
maps are persistent across sessions and are available for further
plotting, analysis, refinement, and culling. |
