Survey files

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.

ArcGIS File Geodatabase Feature Class

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.

  • survey.gdb.zip

Shapefile

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.shp.zip

Textual

Survey Area information is included in the ArcGIS File Geodatabase and shapefile.

Survey area attribute definitions

Survey_Report_ID

Survey Report Identifier

Area_Number

Survey Area Number (Survey Reports can contain one or more   survey areas, using this attribute together with the Survey Report ID   uniquely identifies each survey area)

Report_Title

Survey Report title

Report_Authors

Survey Report author names


Area_Description

Description of the extent of the survey area

Survey_Type

Archaeological, Ethnographic or Archaeological & Ethnographic

Field_Survey

Yes/No. Yes if the survey had a field component.
Note: Published survey areas only include surveys that have a field component (desktop-only   surveys are not included).

Desktop_Survey

Yes/No. Yes if the survey had a desktop (research) component.
Note: Published   survey areas only include surveys that have a field component (desktop-only   surveys are not included).

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.

Coordinate_System

The coordinate system of the source data or survey report map used to capture the boundary (e.g. MGA94 Zone 50, GDA94 Long Lat, AMG84 Zone 50)

Boundary_Last_Update_Date

Date locational information was last updated.

NOTE: Heritage Surveys have been mapped using information from the reports and/or other relevant data sources. Reports may not be held at the Department of Planning, Lands and Heritage (DPLH). Please consult report holder for more information. Refer to Aboriginal heritage for information on requesting reports held by DPLH.
