I need Greek wander paths of places like mountains and forests as shapefiles, but I don't know how to start to extract them from specific sites or getting them ready as shapefiles. I need these data to store them in a Postgres DB and execute some PostGIS queries to find people who have been lost in a region. Can you give me some instructions how to extract these data or sites where I can find them ready?
I have found some sites where you can place your route like these here: wandermap or this OSM specific, but I don't know how to extract the data as shapefiles. More specific, if it is possible I want to make a selection by dropping a rectangle over a region or country and extract these content as shapefiles. Is this possible?. And if yes, how can I achieve this?.
The data are needed to build something like this here: Introduction to web programming for GIS applications
