Welcome to The Nodding Biker's PolyFile Creator!
This utility can be used to create custom map areas for compiling/processing with MKGMAP, OSMCONVERT, OSMFILTER, OSMIUM, OSMOSIS etc.
Right click on map to begin creating polylines or use the "Import" button to load an existing set of Lat/Lon values.
