Western Australia Graticular Blocks

Western Australia's graticular block grid, labelled by block ID.

What it shows

The graticular block grid that Western Australia's mining tenement system is pegged on. Exploration licences and section-40E prospecting permits are granted over whole graticular blocks, so this grid is how a permit's ground is described. It carries two resolutions that swap by zoom: the coarse 5-minute parent blocks read when zoomed out, and the fine 1-minute blocks fade in as you zoom into a local area, each labelled with its block number. Use it to read which numbered block you are standing on and to match a permit's block reference to the ground. It shows the grid only, not who holds each block.

Putting this on your map

Taking a layer from the Library onto a stack, and tuning how it draws, is a short guided tour on your own map.
