TENGRAPH Web is a spatial enquiry and mapping system displaying the position of Western Australian mining tenements and petroleum titles in relation to other land information. It provides a current and accurate picture of land under mining activity and is used to determine ground that is available for mineral exploration.


With the introduction of Tengraph Web, Tengraph Online will be decommissioned Friday 13th December 2019.
