Data Temporal Coverage: 1974-01-01 to 1995-01-01
Geospatial Coverage 141,-39,150,-34
Geospatial Scale 1:25,000
Geospatial Accuracy 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. 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.
