Wednesday, 5 July 2017 UTC

The Open Geospatial Consortium (OGC®) is pleased to announce that Geoscience Australia has raised its membership level from Technical to Principal Level. Geoscience Australia has been an active member of OGC since 1999.

“Geoscience Australia has been a long-time and active member of the OGC, supporting our Technical committee and over 25 of its working groups since 1999,” said Mark Reichardt, President and CEO of the OGC. “I am pleased to announce that GA has elevated its membership to the Principal Level to further extend its support to begin influencing OGC’s market direction, and to ensure that the Consortium’s policies and procedures remain agile and relevant to an ever-changing location technology marketplace."

Geoscience Australia has been a major contributor to developing and promoting international OGC standards for essential datasets, including the Discrete Global Grid Systems (DGGS) standard and the Geoscience Markup Language (GeoSciML) standard. Geoscience Australia is currently participating in OGC’s Hierarchical Data Format 5 (HDF5) data model standardisation working group and its application in domains such as point clouds and global grids.

Landscape Attribute Details

Detailed descriptions of all the products available in the Australian Soil and Landscape Grid can be viewed in the CSIRO Data Access portal metadata records

The landscape attribute products available from the Soil and Landscape Grid of Australia were derived from DEM-S, the smoothed version of the national 1 second resolution Digital Elevation Model, which was derived from the 1 second resolution Shuttle Radar Topography Mission (SRTM) data acquired by NASA in February 2000.

Available Landscape Attributes

Attribute	Description
Slope (%)	Slope measures the inclination of the land surface from the horizontal.
Slope (%) Median 300m Radius	The median slope within a 300 m radius representing the typical slope in the local landscape.
Slope Relief Classification	Slope relief landform pattern classification based on Speight (2009).
Aspect	Aspect measures the direction in which a land surface slope faces. The direction is expressed in degrees from north.
Relief 1000m Radius	The elevation range measures the full range of elevations within a 1000m circular radius and can be used as a representation of local relief.
Relief 300m Radius	The elevation range measures the full range of elevations within a 300m circular radius and can be used as a representation of local relief.
Topographic Wetness Index	TWI estimates the relative wetness within moist catchments, but is more commonly used as a measure of position on the slope with larger values indicating a lower slope position.
Topographic Position Index	Topographic Position Index (TPI) is a topographic position classification identifying upper, middle and lower parts of the landscape.
Partial Contributing Area	Contributing area in m2 computed using multiple flow directions on hillslopes and ANUDEM-derived flow directions in channels.
MrVBF	MrVBF is a topographic index designed to identify areas of deposited material at a range of scales based on the observations that valley bottoms are low and flat relative to their surroundings and that large valley bottoms are flatter than smaller ones.
Plan Curvature	Plan (or contour) curvature is the rate of change of aspect (across the slope) and represents topographic convergence or divergence.
Profile Curvature	Profile curvature is the rate of change of potential gradient down a flow line and represents the changes in flow velocity down a slope.
Prescott Index	The Prescott Index is a measure of water balance that is sensitive to regional climate and local topography and has proven to be a useful in soil mapping both to stratify study areas for sampling and as a quantitative predictor of soil properties.
SRAD Net Radiation January	Mean monthly solar radiation was modelled across Australia using topography from the 1 second resolution SRTM-derived DEM-S and climatic and land surface data.
SRAD Net Radiation July	Mean monthly solar radiation was modelled across Australia using topography from the 1 second resolution SRTM-derived DEM-S and climatic and land surface data.
SRAD Total Shortwave Sloping Surface January	Mean monthly solar radiation was modelled across Australia using topography from the 1 second resolution SRTM-derived DEM-S and climatic and land surface data.
SRAD Total Shortwave Sloping Surf July	Mean monthly solar radiation was modelled across Australia using topography from the 1 second resolution SRTM-derived DEM-S and climatic and land surface data.

Spatial Characteristics

All of the products in the Australian Soil and Landscape Grid conform to the spatial structure specified in the GlobalSoilMap Specifications. Below is a summary of the spatial characteristics of the Landscape Attribute prodcuts.

Using SpatiaLite (for Spatical SQL) - a fast and simple practical how-to for absolute beginners

Following this tutorial will approximately take about an hour or two of your precious time:
that's not a too much demanding task, and you are not required to perform any exceptional effort. 

SpatiaLite is absolutely free (in both meanings: it's free as free beer, and it's free as free speech): so you can get a quick glance at latest state-of-the-art Spatial SQL technologies in the easiest and simplest way. 
And once you've got your own opinion on the basis of your direct first-hand experience, you can then decide by yourself if Spatial SQL can be useful (one way or the other) for your daily activities.
