MP (Polish format, cGPSmapper)

MP, also known as the Polish format, is a plain-text source format invented for the cGPSmapper map compiler. Inside is ordinary text: [POLYLINE], [POLYGON] and [POI] sections, each object carrying a type, a name and a coordinate list per detail level. The file opens in any editor, reads by eye and is edited by hand — that is what the whole amateur mapmaking scene rests on.

Understand this up front: an .mp is not a map for a navigator. No device and no navigation app reads it directly. It is the INPUT to a build: from an .mp you compile the format your device actually understands. There are two chains. First — GPSMapEdit: open the .mp and run Export to Navitel NM2; NM2 is understood by older Navitel Navigator releases, roughly up to 9.1x. Second — the cgpsmapper compiler: it turns the .mp into an .img for Garmin devices.

What we actually deliver. The export writes the geometry of the selected layers, object labels, Polish format types and detail levels — that is, a basic, NON-routable map. The routing graph sections (RouteParam on lines and Nod nodes) are not in the file: they are built at the next step by cgpsmapper and GPSMapEdit themselves. We say this plainly rather than in fine print — if you need a map that works out of the box, take Garmin IMG or OsmAnd OBF, which we compile in full.

We do not produce Navitel's native formats: NM2 is produced on your side, in GPSMapEdit, while NM3 and NM7 are closed and cannot be built by any third-party tool at all. So .mp is the honest maximum the service can offer for Navitel: detailed, fresh OpenStreetMap data in the shape a map is assembled from by hand.
