Victoria Aquifer Framework - Lower Mid-Tertiary Aquifer - Depth to Aquifer Surface

Lower Mid-Tertiary Aquifer - LMTA - 109 - 

The depth to the aquifer layer (metres) is subtracted from the current ground surface.

The Victorian Aquifer Framework (VAF) was developed by the Department of Sustainability and Environment (DSE, now DELWP) to provide a consistent approach to defining, naming and numbering the commonly accepted aquifers, aquitards and geological layers that make up Victoria's groundwater systems. It is intended to assist in the sustainable management of groundwater resources in Victoria and provide the framework for mapping aquifers and aquitards across the State.

The 3D numeric surfaces (grids) of each layer have been styled and converted to GeoTIFF by the VVG project to optimise them for display and querying on the web.
