Vicmap Transport - Airport Polygon

dataset: TR_AIRPORT_AREA_POLYGON
This layer is part of Vicmap Transport and exists is a dataset containing polygon features delineating airport areas. Includes; Airports When capturing the Airport data for the state, some data was captured in polygon form some was captured in line form. To get a more complete portrayal of Airport data, this dataset should be used with the "Airport Infrastucture Area (polygon) - Vicmap Transport" dataset.

Vicmap Transport - Airport Polygon

Department of Transport and Planning

Description

Title
Vicmap Transport - Airport Polygon 
Alternate title
TR_AIRPORT_AREA_POLYGON 
Purpose
Vicmap Transport provides an accurate representation of the Transport network across Victoria, at a capture scale ranging from 1:2,500 to 1:25,000. It is used in a variety of applications, particularly in emergency services, natural resource management, planning and development, and digital map publications.

Lineage

Statement
Dataset Source: The line work and points were derived from the Vicmap Digital Topographic (VDT) map base coordinated by Information Services Branch (ISB) and its predecessors. 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 varies from 1:2,500 to 1:25,000 Statewide and the coverage, except for minor border issues is also statewide. Dataset Originality: Derived 
Description
Collection Method: Conversion of existing mapping, digital stereo capture 
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.

Quality

Attribute Quality
Comments
The allowable error in attribute accuracy ranges between a 1% allowable error to 5% error. For this product attribute accuracy ranges between a 1% to 5% error. For this product attribute accuracy is a measure of the degree to which features and attribute values of spatial objects agree with the information on the source material. 
 
Positional Accuracy
Comments
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. 
 
Conceptual Consistency
Comments
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.
