Outline

Outline

  • What is the Antarctic Digital database?

  • How has it developed?

  • How is it accessed?


What is the add

What is the ADD?

  • A topographic database

  • Primarily a vector database

  • Originally derived from published maps

  • Maintained for SCAR by BAS


What does the add contain

What does the ADD contain?

  • 14 layers including

Coast

Rock outcrop

Contours


What are the add s sources

What are the ADD’s sources?

  • Published maps

    • 7 nations supplied digital data.

    • 3 nations gave permission for maps to be digitised.

  • Ice sheets derived from SPRI folio

    • digitised from 1:3 000 000 compilation sheets.

  • Coastline updated from remotely sensed images.


Development of the add

Development of the ADD

  • Version 1.0 was published on CD in 1993

  • Version 2.0 was published on the internet in July 1998.

  • Version 3.0 was published in July 2000.

  • Version 4.0 was published in August 2002

  • Version 4.1 November 2003

  • Version 5 went live in August 2007

  • Incremental updates since then.


Version 2 0

Version 2.0

  • First version on the Internet

    • http://www.add.scar.org/

  • Included many structural corrections.

  • Some new data between 0 and 90°W.


Version 3 0

Version 3.0

  • The first major upgrade to the content of the ADD

  • Ice sheet contours replaced

    • Based on altimetric DEM provided by Byrd Polar Research Center.

    • Result of collaboration between BPRC and BAS


Improved contours

Improved contours


Version 4 0

Version 4.0

  • New coastline for the sector between 30°W and 168°W

  • New data for Prince Charles Mountains

  • New coastline for Antarctic Peninsula

  • Position of Antarctic Peninsula data corrected.


Version 4 1

Version 4.1

  • New rock outcrop for the Antarctic Peninsula.

  • Detailed corrections to coast in Antarctic Peninsula


Version 5 0

Version 5.0

  • Complete revision of the web site

  • Provision of Web Feature service

  • Provision of Web Map service

  • New data including:

    • Coastal change in the Antarctic peninsula

    • Subantarctic Islands

      • South Georgia

      • Heard and Macquarie Islands

  • Made compatible with the Antarctic Spatial Data Infrastructure

  • Went “Live” in August 2007

  • Continuing incremental upgrades


Add data management

ADD Data management

  • Originally held as tiled ARC/INFO coverages

  • Still edited and maintained as coverages

    • Maintained using ESRI software

  • Working copy held in PostgreSQL/PostGIS


Add and data standards

ADD and data standards

  • ADD originated when there were no standards to follow!

  • Now provided in wide variety of OGC compliant formats including:

    • WFS (OGC WMS 1.1.1)

    • WMS (OGC WFS 1.0 )

    • GML (ISO 19136 and OGC)

    • KML (became OGC standard recently)

  • Working towards compliance with:

    • ISO 19115 (Metadata)

    • ISO 19110 (Antarctic Feature Catalogue, maintained by Australia)


Added value products

Added Value Products

  • Antarctic Maps for Garmin GPS

    • BAS has created maps for use in Garmin GPS with map display

      • Hill shaded topography

      • Contours (labelled where accurate)

      • Rock outcrop

      • Coast, ice shelf, ice rumple

    • Field tested 2008-2009 field season

    • Modifications in line with experience being implemented

    • Contact BAS for further information

    • Will only be made available to experienced Antarctic operators.


The future

The Future?

  • Improve data content

  • Add new data layers

  • Improve access

  • Integrate with other data sources:

    • Composite Gazetteer of Antarctica

    • UK Antarctic Placenames Committee


Conclusions

Conclusions

  • ADD provides the best topographic data for the whole of Antarctica.

  • ADD provides the essential underpinning for:

    • Operations.

    • Scientific investigations.

  • ADD is an ongoing programme.

    • Mapping Antarctica is a work in progress!
