Here are examples of using on-line and purchased maps for use in mapping gold locations. This example is Moliagul Victoria - home of the 'Welcome Stranger' nugget. What I do is collate all this data, do conversions, usually from chains and/or miles to metres and create a series of re-aligned overlays and create a new map. To get best resolutions, i usually go for tifs and use the snipping tool to cut and paste my maps. Hope this is of interest. (Hope its not too big memory wise Nugget)
