ATA geological units (v.2019-07)
This layer comprises geological unit data for Antarctica. It represents a synthesis of existing published and unpublished mapping of the geology of this area in a single dataset at a regional scale. These data comprise polygon geometry with each polygon having attributes describing the unit type, name, age, lithology, stratigraphy, and supporting background information, where this is known. This layer complies with the GeoSciML Lite standard for GeologicalUnitView and fields required by that standard were populated using the CGI Controlled Vocabulary (v2016.01).

- Statement
-
1. High resolution geographic information layers sourced from SCAR Antarctic Digital Database (ADD) consisting of a rock polygon layer, moraine polygon layer and water polygon layer.
2. Landsat Image Mosaic of the Antarctic (LIMA) or other imagery was used to correct spatial location of combined polygon feature class. Additional rock outcrops and surface deposits were digitised from LIMA imagery.
3. Existing published or unpublished geological maps were georeferenced and used to assign a source geological unit code to spatially corrected polygons of outcropping rock. In some cases, existing GIS layers or research papers were used to assign a source geological unit code.
4. LIMA imagery and Reference Elevation Model of Antarctica (REMA) elevation data were used to identify surface deposits and assign source geological unit code.
5. A GeoSciML compliant table of attributes were compiled for all source geological unit in each dataset using MS Excel. This table includes a generalised chronostratigraphic code consistent throughout the GeoMAP geological unit data.
6. The table of attributes is checked for consistency and appended to the polygon geometry.
7. Data checked for logical consistency.
