Groote Eylandt 1:250,000 Topographic Map Sheet

AUSTopo 1:250,000 digital topographic map covering the Groote Eylandt area. The map series comprises 516 sheets, the largest scale covering the entire Australian continent. It contains natural and constructed features like roads, vegetation, hydrography, and 50-meter contours.

Use Cases

• Extract road and rail infrastructure features for regional transportation network analysis.
• Analyze hydrography and 50-meter contour intervals for terrain modeling and watershed delineation.
• Identify vegetation coverage and administrative boundaries for land-use planning studies.
• Combine map sheet data with neighboring sheets for seamless spatial analysis where standard sheets are largely ocean.

Strengths

• Part of a continent-wide series of 516 topographic maps at 1:250,000 scale.
• Contains multiple feature classes including infrastructure, vegetation, hydrography, and contours.
• Uses standardized coordinate systems (GDA94, GDA2020) and UTM projection.

Limitations

• Data is provided only in PDF format, requiring extraction for GIS or analytical use.
• Map may contain information from surrounding sheets, potentially complicating precise area-of-interest analysis.
