BA SYD 1 sec SRTM (h) DEM and hydrological derivatives

Abstract

The dataset was derived by the Bioregional Assessment Programme from the Geoscience Australia, 1 second SRTM Digital Elevation Model (DEM) dataset. The source dataset is identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.

This data is an extract from the 1 second hydrologically enforced SRTM, clipped to a rectangle to take in the extent of the BA_SYD bioregion and its contributing subcatchments (BA_SYD_DEMh1sec).

The data is extracted from

Geoscience Australia, 1 second SRTM Digital Elevation Model (DEM)

GUID: 9a9284b6-eb45-4a13-97d0-91bf25f1187b

Three additional layers are derived from this data for hydrological analysis and catchment delineation. They are:

BA_SYD_DEMh1sec_fill: as above but with sinks filled

BA_SYD_FDIR: Flow direction

BA_SYD_FACC: Flow accumulation.

Purpose

Hydrological analysis and contribution catchment delineation

Dataset History

This data is an extract from the 1 second hydrologically enforced SRTM, clipped to a rectangle to take in the extent of the BA_SYD bioregion and its contributing subcatchments (BA_SYD_DEMh1sec).

The data is extracted from Geoscience Australia, 1 second SRTM Digital Elevation Model (DEM) using the Spatial Analyst "Extract by Rectangle" tool snapped to the source raster.

GUID: 9a9284b6-eb45-4a13-97d0-91bf25f1187b

Three additional layers are derived from the extracted DEM using the respective Tools in the ArcGIS Spatial Analyst-> Hydrology toolset. They are:

BA_SYD_DEMh1sec_fill: as above but with sinks Filled

BA_SYD_FDIR: Flow Direction

BA_SYD_FACC: Flow Accumulation.
