Description

Abstract:

Outcrop geology was obtained directly from the following four map sheets:

Marble Bar (1:250K), Nullagine(1:250K), Yarrie(1:250K) and Port Hedland

(1:250K).

Original credits as on map sheet are:

Marble Bar - Hickman, A.H, and Lipple, S.L, 1972

Nullagine - Thom, R, Hickman, A.H and Chin, R.J, 1973

Yarrie - Hickman, A.H, Chin, R.J, Gibson, D.L, 1982

Port Hedland - Hickman, A.H, and Gibson, D.L, 1981

An adjustment was carried out of the original outcrop geology.

This adjustment was primarily carried out with the aid of Landsat -5 TM imagery.

Data quality

Lineage:

Original data was captured at 1:25,000 scale and published at 1:250 000 scale. This data was scanned and digitised with Intergraph software and then imported into Arc/Info software. Due to poor topographic bases from original data it was decided to adjust the solid geology lines to better fit the landsat image which was a more accurate example of the geology.

Positional accuracy:

Cross-checking with landsat 5TM satellite imagery. It can be estimated that about 95% of all features could be expected to have an accuracy within 150 metres.

Attribute accuracy:

Attribute data was obtained from a) outcrop geology mapping shown in the 1:250k map sheets of Marble Bar, Nullagine, Port Hedland and Yarrie, b) where outcrop geology mapping was absent, an interpretation of magnetics images plotted with a resolution of 180m was used.

Logical Consistency:

Some of the data has been checked in the field with mixed results. While line data had a high degree of accuracy, polygonal data seemed to vary. This was mostly due to conflicting opinions between original mapping and subsequent field mapping.

Completeness:

All geological units with an area of greater than 20,000 square metres are represented in this layer which covers the entire dataset area.
