Digital information is provided in both spatial and textual form. Spatial information is available in a number of formats.
The department stores the location and extent of Aboriginal Heritage Survey Areas in an ESRI ArcSDE feature class, and Survey Area information is recorded as attributes.
An ArcGIS File Geodatabase is available within a zip file, a survey feature class is stored within the file Geodatabase and is equivalent to the ESRI ArcSDE feature class source format. In order to access the dataset the file Geodatabase must be extracted from the zip file first.
A Shapefile is created by exporting from the ArcSDE feature class, and is made available with a zip file. In order to access the dataset all files must be extracted from the zip file first.
Survey Area information is included in the ArcGIS File Geodatabase and shapefile.

Boundary_Reliability
One of the following: Very Good, Good, Moderate, Unreliable or Indeterminate.
The following definitions strictly apply to the spatial accuracy of heritage survey boundaries as captured by DPLH:
Very Good: Boundaries captured from surveyed titles, GPS (2001 onwards) submitted maps georeferenced to within 20m accuracy. Good / Moderate: Boundaries captured from GPS (pre 2001) submitted maps georeferenced to within 250m accuracy. Unreliable Boundaries captured from submitted maps georeferenced to an accuracy exceeding 250m. Indeterminate Surveys submitted with insufficient information to allow reliable boundary capture.
