Will the Large Synoptic Survey Telescope find Planet 9 within "the first year of data"?
On 20 January 2016, researchers Konstantin Batygin and Michael E. Brown at Caltech announced a calculation-based evidence of a massive ninth planet in the Solar System.
Planet Nine would be 10 times the mass of Earth (approximately 5,000 times the mass of Pluto), and have an orbit that is so far away that it could take it 15,000 Earth years to orbit the Sun. It would most likely be an ice giant with a thick atmosphere of hydrogen and helium.
However, as Zeljko Ivezic (Large Synoptic Survey Telescope Project Scientist) suggests “if it exists, might be too small to be discovered with ongoing sky surveys, but large enough to be discovered even with only the first year of LSST data! That would be a great way to start the survey!”
Sparx Systems Enterprise Architect is providing a scalable, shared model to integrate the work of the geographically dispersed LSST team. Enterprise Architect has delivered complete requirements traceability, round-trip code engineering and detailed SysML support.

Standards, Interoperability and Innovation
"No man is an island, entire of itself; every man is a piece of the continent; a part of the main;"
- John Donne
Connectedness:
As the impact from the digital industrial economy takes effect, not only will it inform enterprise how to successfully leverage globally interconnected technology to deliver results according to the mission and vision of the company - the impact will drive the need to digitally renew the business. A connected world eliminates silos and the extent of connectivity determines levels of inclusion in the digital economy, the quality of services and products and the resulting customer loyalty.
Innovation from Inspiration:
Innovation is a palimpsest of disruptions, evidence that the advances of modern science are inspired by the achievements of the past. The majority of innovative ideas take products, services or processes that are already working and improve on them. One clear example is the Large Synoptic Survey Telescope (LSST) which, when completed, will provide unprecedented information about distant galaxies, nearby asteroids and the dark energy that is accelerating the expansion of the universe. It will boost technological development and ‘has the potential to transform our knowledge of the universe’ which for centuries, was inspired by Ptolemy.
The stars have provided pointers for the earliest exploratory excursions of mankind and Ptolemy’s Almagest published in the first century, is a codification of the constellations and a catalogue of the fixed stars. For 1400 years, it was the standard astronomical reference and one of the most influential books in the history of Western astronomy. Still today, standards support industry competitiveness, improve performance and enable technology such as the LSST. They do this by assisting with the codification and dissemination of new knowledge and innovations and ensuring interoperability.
Interoperability:
Across every industry sector, Sparx Systems directly supports standards development and those enterprise architects who rely on standards to navigate business enterprise through rapid and unprecedented change. In the burgeoning geospatial sector open standards enable organizations to take advantage of new geospatial information sources and technology tools and they are a central element of open government. Interoperability is a key aim of open standards and their development offers stakeholders such as governments, universities, research organisations and business enterprises the opportunity to participate in their development.
Integration:
Within the geospatial market, standards are driving rapid change and technology deployment while creating new cross - domain opportunities. The United Nations initiative on Global Geospatial Information Management (UN-GGIM) provides leadership in setting the agenda for the development of global geospatial information and promoting its application to address key global challenges.
The United Nations Committee of Experts on Global Geospatial Information Management was formed in 2011. Later that year, the First High Level Forum on Global Geospatial Information Management, and the First Session of the United Nations Committee of Experts were held in Seoul, Republic of Korea. Experts from 90 countries met to enhance global cooperation in the field of geospatial information management.
Information Accessibility:
In 2012 the Secretary General of the UN Economic and Social Council identified “better integration of geospatial and statistical information, as a key challenge” in meeting information needs and in 2014 the United Nations Global Forum on the Integration of Statistical and Geospatial Information took place. The UN Expert Group on the Integration of Statistical and Geospatial Information is developing a global statistical-geospatial framework – modelled on the Statistical Spatial Framework (SSF) developed by the Australian Bureau of Statistics (ABS). This Framework will provide a common approach to connecting people-centric (socio-economic) information to a location, and improve the accessibility and usability of this spatially-enabled information.
Standards:
The spatial and statistical communities operate different metadata capabilities and approaches to ensure that these two metadata environments can work together effectively are being investigated. Metadata standards being reviewed include: Statistical Data and Metadata Exchange (SDMX), Data Documentation Initiative (DDI), and the international geospatial metadata standard ISO19115.
The recently released Address Standard ISO 19160-1 defines a conceptual model for address information together with the terms and definitions that describe the concepts in the model. The model provides a common representation of address information, independent of actual addressing implementations and a means to cross-map between different conceptual models for address information and enables the conversion of address information between specifications. The Address Standard is essential to the aims of the SSF in the sharing, accessing and dissemination of information.
Collaboration:
Sparx Systems continues to support both the global statistical and geospatial communities and has enhanced Enterprise Architect with the inclusion of profiles for ArcGIS and GML for this sector. In addition, through our collaboration program, Sparx Systems has partnered with CSIRO to support the ongoing development of model registry features and functionality for Enterprise Architect.
As stated by Geoffrey Sparks, Sparx Systems CEO in a recent interview, “I am strongly committed to the development and implementation of common, well understood modeling languages that enable disparate domains to communicate and integrate their specific processes and architectures into a single, well understood platform.”
In the coming years Sparx Systems imagines new tools and information processing capabilities that further support the transformation of models into executable form.
