Quality

Conceptual Consistency

The allowable error in attribute accuracy ranges between 1% to 5% error. Logical consistency is a measure of the degree to which data complies with the technical specification. The test procedures are a mixture of scripts, microstation MGE program and on-screen visual checks.

Positional Accuracy

The planimetric accuracy attainable will be the sum of errors from three sources:the positional accuracy of the source material, errors due to the conversion process, errors due to the manipulation process. For topographic base derived data this represents an error of 8.3m on the ground for 1:25,000 data. A conservative estimate of 10m for the standard deviation will be used in any data quality information. Alternate and equal ways of expressing this error are: not more than 10% of well-defined points will be in error by more than 16 m. The worst case error for the data is +/- 30 m. For vertical positional accuracy of points determined from contours there is an expectation that the elevation accuracy (standard deviation) will be half the value of the contour interval. 

Lineage

Description

- Conversion of existing mapping - compilation conversion 30% and repromat conversion 50% - digital stereo capture - 20% -The majority of the conversion of existing mapping and approximately 30% of the digital stereo capture were outsourced to private contractors and the remainder was captured in house. Contractor's primarily scanned and vectorised existing repromat with a small amount of hand digitising done in some instances. 

Statement

Dataset Source: The line work and points were derived from the Vicmap Digital Topographic (VDT) map base coordinated by LIG. VDT evolved from Victoria's printed 1:25,000 Topographic Map Series program together with the need to supply a control framework for the creation of the rural Digital Cadastral Mapbase. The capture scale is 1:25,000 Statewide and the coverage, except for minor border issues is also statewide. Dataset Originality: Primary
