Description

Abstract:

The 1:250 000 scale geological map series now covers almost all of Australia and has been produced over many years by AGSO and its counterpart state bodies. The quality of maps has improved steadily over the years. Modern maps are produced with the aid of satellite images and aircraft-obtained magnetic and gamma-ray images.

Data quality

Lineage:

The data on 1:250 000 geological maps have be gathered from mission-specific fieldwork and various other sources that are generally detailed on the face of the map, or in the accompanying documentation.

Positional accuracy:

The positional accuracy of features on the face of 1:250 000 geological maps varies widely, but should be better in more recent maps than those produced over 20 years ago. For maps produced in the last 20 years from air photography and satellite images, most geological features should be accurate to within one or two millimetres on the face of the map (250-500 metres on the ground). More recent observations obtained with the help of GPS equipment may be accurate to 100 metres on the ground. In general, solid geogical boundaries should be more accurate than dashed boundaries, which are in turn more accurate than dotted boundaries.

Attribute accuracy:

Every effort is made to ensure the the accuracy of attribute information on the face of 1:250 000 geological maps, but in many instances there is an element of interpretation. In particular, the attribution of an outcrop to a particular formation may be subject to revision, and the definition of formations can change in time.

Logical Consistency:

The geologists engaged in geological mapping generally go to a great deal of trouble to ensure that the geological information portrayed on the face of their maps is logically consistant. However, opinions can differ, and what one geologist regards as logically consistent may not satisfy another geologist. Modern maps are generally better than some of the older examples, as account is now taken of such things as balanced sections and sequence stratigraphy.

Completeness:

Most 1:250 000 geological maps can be considered as being complete, although the degree of completeness may vary somewhat. Modern maps tend to have a lot more detail on them than was the case 30 years ago.
