Geoscience Australia`s involvement in Papua New Guinea mapping includes managing the production of maps for select urban areas as part of a MOU between Department of Defence and PNG.
In addition, Geoscience Australia distributes some (now aging) 1:100,000 scale maps produced by the Department of Defence for much of Papua New Guinea.
At this scale 1cm on the map represents 1km on the ground. Each map covers a minimum area of 0.5 degrees longitude by 0.5 degrees latitude or about 54 kilometres by 54 kilometres. The contour interval is 20 metres. Many maps are supplemented by hill shading.
