mp2osm GUI
This GUI enables you to extract POIs,highways, polygons and contours from img files.
There are quite a few programs which purport to convert 'mp' into 'osm' files but all require a decent knowledge of Perl. Mp2osm GUI is designed to assist those who use Windows and just want the process to be automated.It can only cope with 50,000 nodes.

What does it do?
- It translates mp into osm files - Garmin's img files can be converted into an mp format using a free tool GPSMapEdit .
- In theory , it means that all non-locked imgs can be uploaded to OpenStreetMap ; to ensure copyrights are not infringed mp2osm generates osm files which cannot be imported into current versions of JOSM or Merkaartor.
- Gives you the option to parse only POIs or highways etc..
- It highlights any POIS,highways or polygons contained in the mp file which are not parsed .You can create your own 'filter' by editing the POI,highway or polygon list.
- In addition,your mp files can now be shown on google earth using our osm2ge program.
Why have a convertor?
There is generally no reason to convert mp into osm files as you can simply strip the required POIs,highways or polygons from any mp file, say streams (0x18) or contours (0x20,0x21 etc) and resave them as a new mp file. However, osm files do support routing and so in theory you can create routable imgs from all mp files. |
For those interested consider this :
- Decide on your datum, ie WGS84.
- Calculate the min and max latitude and longitude boundaries.
- Establish how many nodes you need.
- Convert POI types to osm equivalents ,ie &2f17 = bus-stop - this can be quite tricky but use img2typ.exe to help you.Our mp2osm convertor will highlight any POIs,highways or polygons which haven't been parsed . Just edit your conversion list.
- No need to include all osm tags like,authorship or timespan.
- create a database of all coordinates.
- Check which nodes are shared
- Now work on your polylines or polygons. Establish correct links to each coordinate.
Be aware : these references cannot and DO NOT tally with the IDs found in Openstreetmap
- see polylines
- Relations are tricky.

This gui has had to be withdrawn temporarily, as it was not meant for uploading to OpenStreetMap.
