These steps show how to calibrate scanned maps.
In this example we work with Polish projection - Borowa Gora

For the last 3 years I have been almost exclusively providing cartographic services for Bezdroza, one of the largest tourist guide publishers in Poland. Bezdroza has a distinguished protfolio of books and therefore the maps they publish may vary a lot, although they are usually rather guide-like maps like:
This time I was invited as a cartographer to take a part in a project that appeared to be quite unusual - I was to design maps for a book of travel. Nothing unusual so far, rigth? The unusual part was that the book was not to have any maps inside, the maps were supposed to make the cover of the book.
The book tells a story of two journalists that decided to travel around the world on their motorbikes. When they agreed it would be a great fun, they did not have their motorbike driving licenses nor they could ride the bikes. This made me think that it should be fun for me too to design such a cover for this book.
The data came from the Natural Earth data repository and from the GPS tracks supplied by the authors of the book.
For the front cover map I used the the 1:100M data set and generalised GPS data; for the back cover both source datasets were generalised even further.
When designing the 17 globe maps for the back cover I was tempted to script the data preparation process (prepare the data, center and project it, and finally clip it) though after all I took the quicker path and decided to create them manually. Maybe next time, when we are about to design some globe maps for the folks that visited more than 20 countries ;-)
Designing these maps was an enjoyable experience, hopefully you'll like them too.
