Description
Abstract: 
Contains a medium scale vector representation of the topography of Australia. The
data include the following themes: Hydrography - drainage networks including
watercourses, lakes, wetlands, bores and offshore features; Infrastructure -
constructed features to support road, rail and air transportation as well as
built-up areas, localities and homesteads. Utilities, pipelines, fences and
powerlines are also included; Relief - features depicting the terrain of the
earth including 50 metre contours, spot heights, sand dunes, craters and cliffs;
Vegetation - depicting forested areas, orchards, mangroves, pine plantations and
rainforests; and Reserved Areas - areas reserved for special purposes including
nature conservation reserves, aboriginal reserves, prohibited areas and water
supply reserves.

Data quality 
Lineage: 
TOPO 250K Series 2 is primarily sourced f rom TOPO 250K Series 1 and 1:250 000 scale
map reproduction material (from the National Topographic Map Series and Defence Joint
Operation Graphics). A key revision source for the data is satellite imagery taken
from the SPOT Panchromatic and LANDSAT Thematic Mapper Sensors. Revision material
has also been gathered from a variety of authoritative sources. More information
about the sources for this data can be found in Geoscience Australia's Topographic
Data and Map Specifications. 
Positional accuracy: 
Geoscience Australia has carried out both error budget analysis and field tests to
verify the positional accuracy of the data. TOPO 250K Series 2 data complies with
the following statement of horizontal accuracy: "The summation of errors from all
sources results in data with a standard deviation of 85 metres for well defined
features". Alternative and equal ways of expressing this error are: Not more than
10% of well-defined points are in error by more than 140 metres; and In the worst
case, a well defined point is out of position by 300 metres. As the TOPO 250K Series
2 data were digitised from existing map production material, some features may be
subject to cartographic displacement. A full description of the features that may
have been displaced and the range of displacement that may have occurred due to
generalisation are provided in the TOPO 250K Series 2 Data Quality Statement
supplied with the data. An estimate of the standard deviation of planimetric error
of each feature instance is given in the Data Quality Table. Vertical Accuracy:
The accuracy of the spot elevations in the relief layer varies with the type of
source material from which they were captured and the point determination for each
particular point. Most spot heights have an accuracy of + or - 5 metres, however
bench marks and horizontal control points have an accuracy of + or - 1 metre. The
accuracy of contours is defined as 1/2 of the contour interval, for example + or
- 25 metres for a 50 metre contour interval. 

Attribute accuracy: 
For the TOPO 250K product, attribute accuracy is a measure of the degree to which
the attribute values of features agree with the information on the source material.
The allowable error in attribute accuracy ranges from 0.5% to 5%, at a 99% confidence
level. Where less than 1% of attribute errors are permissible the entire population
is tested. Where a less stringent limit is set for allowable errors a random subset
of the relevant features in the tile is generally tested. The sample size is
determined from statistical tables using the known population size of the relevant
feature. Further information on the validation and testing methodology used by
Geoscience Australia can be found in section 3 of the TOPO 250K GEODATA Specifications. 

Logical consistency: 
Validating logical consistency may involve tests to check that table and file names
are set out as in the Data Dictionary. Also included are graphical test s which check
such things as intersections, polygon closure, minimum sizes of polygons and
topological relationships. The allowable error in logical consistency ranges from 0%
to 5%. Further information on the validation and testing methodology used by
Geoscience Australia can be found in section 3 of the TOPO 250K GEODATA Specifications. 

Completeness: 
All instances of a feature and its attribute values that appear on the source material
are captured unless otherwise indicated in the selection criteria for that feature.
