ATA GeoMAP quality (v.2022-08)
This layer comprises a quality assessment of the compiled data for SCAR GeoMAP v.2022-08 geological dataset of Antarctica. It represents an assessment of the extent of data captured, and an assessment of attributed information of this area as a gridded dataset, made by the compiler of this dataset. It is intended that this will provide an indicative assessment of the quality of the dataset for end users, together with information on regions that would benefit from further investigation. These data comprise polygon geometry with each polygon having attributes describing an assessment of quality the encompassed area based on the capture of rock outcrop geology, fault and structural measurement mapping, and supporting comments. Each polygon covers a grid area of 1 degree of longitude and 15 minutes of latitude.The relative ‘quality’ is ranked on a scale from 5 to 1, where:5 is highest. Bedrock geology has been captured from mapping at 1:250,000 or more detailed; Cover sequences and occurrence of seasonal water have been reviewed and classified from ground studies, or aerial or satellite imagery; faults and structural data have been captured; rock outcrop polygon areas have been checked against LIMA or other satellite imagery (accurate to +/-100m); links to a source bibliography are complete.4. Bedrock geology has been captured from mapping at regional scale (mostly less than 1:250,000); Cover sequences and occurrence of seasonal water have been reviewed and classified from aerial or satellite imagery, but there may not be local studies to constrain age; faults and structural data will generally have been captured; rock outcrop polygon areas have been checked against LIMA or other satellite imagery (accurate to +/-200m); links to a source bibliography are complete.3. Bedrock geology has been captured from mapping at regional scale (mostly greater than 1:250,000); Cover sequences and seasonal water have been mapped but information for classification is limited; some faults and structural data have been captured; there has been some checking of rock outcrop polygon areas against satellite imagery (accurate to +/-500m); further links to bibliographic sources could be added.2. Bedrock geology may be well-constrained, or alternatively interpreted at large scale mapping (e.g. greater than 1:1,000,000); There has been very limited review of cover sequences and seasonal water; faults and structural data are unlikely to have been captured; rock outcrop polygon areas could be improved by checking against satellite imagery (only accurate to +/-1000m).1. is lowest. Quality rank refers to the early stages of work where little or no information has been attributed to rock outcrop polygons; and polygons have not been checked for their locational position and/or shape. In some places there is no information to assign (where outcrops may not have been visited or had geology inferred) in which case polygons have been attributed as ‘unknown’. There are still quite a few places in Antarctica where an entire 1 degree x 15 minute grid polygon appears to be unknown and quality = 1. A quality rank of 0 indicates that no mapable geological feature is recorded in this area.The GeoMAP dataset was produced as part of the Regional Geological Map Archive and Datafile, one of the Nationally Significant Collections and Databases supported by the New Zealand Government’s Strategic Science Investment Fund (contract C05X1701).DOI https://doi.org/10.21420/7SH7-6K0 5
