GEODATA TOPO 100K ACT Region

Brief description

GEODATA TOPO 100K ACT Region is a vector representation of the major topographic features appearing on the ACT Region NATMAP 1:100,000 scale topographic map. An ECW of the ACT Region NATMAP is also available as part of this product. It has been
specifically designed for use in Geographic Information Systems (GIS) and provides high quality data for mapping and GIS professionals.
The data is available in three popular GIS formats (ESRI Personal Geodatabase, ESRI Shapefiles and MapInfo mid/mifs) as well as a raster (ECW). They can
either be individually downloaded for free, or all formats can purchased as a single packaged CD-ROM product by contacting the Geoscience Australia Sales Centre.

Lineage

Maintenance and Update Frequency: asNeeded

Statement: GEODATA TOPO 100K ACT Region was generated from the 100K ACT Region NATMAP hardcopy map released in early 2005. The map was revised from previous editions and revision material including:
- SPOT and Landsat satellite imagery;
- Revision data (i.e. airfields, vegetation, dams, utilities, foot tracks, mines, railways and towers);
- Reproduction material (i.e. map production material from previous maps); and
- Public feedback.

The digital files used to create the map were converted to topographic data to be in line with Version 4.0 Specifications.
