Query Driven Visualization of Astronomical Catalogs
Hugo Buddelmeijer, Edwin A. Valentijn

TL;DR
This paper introduces a query-driven visualization approach for astronomical catalogs, enabling scientists to request and visualize data interactively with high abstraction, improving data sharing and processing efficiency.
Contribution
It presents a novel query-driven visualization method that integrates data pulling with declarative catalog requests and enhanced messaging protocols.
Findings
Implemented in Astro-WISE system
Supports new messaging protocols
Enables interactive, high-level data requests
Abstract
Interactive visualization of astronomical catalogs requires novel techniques due to the huge volumes and complex structure of the data produced by existing and upcoming astronomical surveys. The creation as well as the disclosure of the catalogs can be handled by data pulling mechanisms. These prevent unnecessary processing and facilitate data sharing by having users request the desired end products. In this work we present query driven visualization as a logical continuation of data pulling. Scientists can request catalogs in a declarative way and set process parameters directly from within the visualization. This results in profound interoperation between software with a high level of abstraction. New messages for the Simple Application Messaging Protocol are proposed to achieve this abstraction. Support for these messages are implemented in the Astro-WISE information system and…
