Hi Bourke

Some more information to help you, we are not after detailed mapping at the
moment, just basic transportation, roads, rivers, forests, etc. Also, some
of this area is very sparsely populated and lot sf it is covered by Tree
Canopy and there are a lot of Clouds covering the area as well. The area is
quite large and to keep the tile count down to a manageable size, we chose
this zoom level.

Later, new tasks will be created with smaller squares for mapping in detail
in specific areas, we will use the information captured in this Project to
determine those mapping needs.

Best Regards

Mark Cupitt
