Definition
Completeness relates to the degree the data collected is as intended and complies with minimum requirements as per ASB standards. The Completeness Assessment is a cursory examination of data acquired or submitted to detect any obvious data gaps. This applies to the presence of required attributes, metadata, and acquisition reports detailing survey scope and any information relevant to the collection and supply of the dataset. This check consists of two elements: Commission (excess or duplication) and omission (missing files/data).
Checks
Missing files, as apart from the subsequent Logical Consistency Assessment, are noted on a cursory check of supplied data (verify files are present).
Date of data reception is recorded.
Is the data published and available elsewhere?
Survey priority in the context of the Publication Schedule has been assigned.
Metadata including additional ancillary data is supplied as per outline of data submission. Storage on the Clearing House NAS has been allocated.
Pass Requirements
External/internal dataset review. Data is identified as from a ‘Registered Contributing Partner’ or otherwise noted. Data submission retains a logical consistency to expectations (files appear consistent with initial data submission documents):
L0 data – have initial QAX QA/QC checks been completed?
L2 data – initial QAX report included with data?
L3 data – minimum requirement of three band GeoTIFF (density, uncertainty, depth) - horizontal datum cannot be Mercator projection.
