  • The SCAR Spatial Data Model has been developed for Geoscience Standing Scientific Group (GSSG). It was presented to XXVII SCAR, 15-26 July 2002, in Shanghai, China. The Spatial Data Model is one of nine projects of the Geographic Information Program 2000-2002. The goal of this project is 'To provide a SCAR standard spatial data model for use in SCAR and national GIS databases.' Activities within this project include: 1. Continue developing the SCAR Feature Catalogue and the SCAR Spatial Data Model 2. Provide SCAR Feature Catalogue online 3. Creation and incorporation of symbology 4. Investigate metadata / data quality requirements 5. Ensure compliance to ISO TC211 and OGC standards Source: http://www.geoscience.scar.org/geog/geog.htm#stds Spatial data are increasingly being available in digital form, managed in a GIS and distributed on the web. More data are being exchanged between nations/institutions and used by a variety of disciplines. Exchange of data and its multiple use makes it necessary to provide a standard framework. The Feature Catalogue is one component of the Spatial Data Model, that will provide the platform for creating understandable and accessible data to users. Care has been taken to monitor the utility of relevant emerging ISO TC211 standards. The Feature Catalogue provides a detailed description of the nature and the structure of GIS and map information. It follows ISO/DIS 19110, Geographic Information - Methodology for feature cataloguing. The Feature Catalogue can be used in its entirety, or in part. The Feature Catalogue is a dynamic document, that will evolve with use over time. Considerable effort has gone into ensuring that the Feature Catalogue is a unified and efficient tool that can be used with any GIS software and at any scale of geographic information. The structure includes data quality information, terminology, database types and attribute options that will apply to any GIS. The Feature Catalogue is stored in a database to enable any component of the information to be easily viewed, printed, downloaded and updated via the Web.

  • Antarctica is the world's greatest remaining wilderness area. It plays a significant role in many global environmental issues such as wind and water currents and world weather patterns. State of the Environment Reporting: - provides a 'snap-shot' of the status of the Antarctic environment - relies on long-term monitoring of environmental and other variables - allows the detection of trends and patterns, which may be due to natural variability or human-induced (anthropogenic) pressures Why are we interested? State of the Environment Reporting allows us to: - assess the quality of the Antarctic environment - identify threats to the Antarctic environment - monitor the pressures we exert on it and track the impact and efficiency of our activities in the Antarctic. How do we do it? State of the Environment Reporting is based on environmental indicators. Indicators: - are data that summarise physical, chemical, biological or socio-economic factors which best represent the key elements of the environment - are grouped into themes We have developed a web-accessible computer system called SIMR that manages the indicator data, metadata, and custodian information. The system automatically prompts custodians for data and evaluations when required and can produce reports on indicators via the web whenever requested.

  • The snapshot (originally produced on CD for a conference) was produced by the Australian Antarctic Data Centre for distribution to Heard Island expeditioners in the 2003/2004 season. The snapshot contained all publicly available data held by the Australian Antarctic Data Centre related to Heard Island at the time of production. The snapshot also contained all metadata held by the AADC at the time of production. Furthermore, information is also included from: AADC's gazetteer biodiversity database satellite image archive gis shapefiles heard island wilderness reserve management plan Finally, freely available software needed to browse some of the data are also included.
