Generating Garmin Map


First U require some software:
1. Routable cGPSmapper (http://www.cgpsmapper.com/buy.htm)
2. OziExplorer (http://www.oziexplorer.com/)- required if photographic imagery is going to be used as a reference source
3. MapSource
4. If u have a google map You may use Geopainting GPSMap Edit (http://www.geopainting.com/en/) or Cartopro Evolution(http://cartopro.com/indexEn.php)

Use oziexplorer (or GPS map edit...) to load the image (File/Load and Calibrate Map) then Calibrate the photograph using a good point of reference (cross street, landmark, coastline, way points etc). The accuracy of the calibration can be determined by enabling the grid inside OziExplorer under Map/Grid Line Setup). On the map, add points of reference that can be imported into GPSmapper that will allow generation of the necessary map detail To generate the tracks click the "Show" icon with the blue line (just under the Moving Map menu), and then click "track". Before drawing each track, make sure that a clear box is at the top of the track list. When the track has been drawn, save each track into a separate file (Ozi Explorer PLT format). Likewise when you're happy with all of the positions for the way points, save these as well (Ozi Explorer WPT format). Modify the example text file given. Example has two files, one for each of the example golf courses mission_trails_img.txt and mt_woodson_img.txt. A final third file brings in all of the individual maps together into a single group Included in each of these files is a list of all of the PLT and WPT files generated and the symbol to assign to it. An explanation of the file format is given in the GPSMapper SampleMap directory, but as a summary RGN10's are Points of Interest, RGN20's are simple points/cities, RGN40's are streets, railroads, and streams etc, RGN80's are regions such as lakes and reservations. Each region has its own set of codes that can be used. In example Adam New Ham declared the fairways as RGN80, with a hex number of 0x18, i.e. Golf. Likewise for the Way Points he used RGN10 and 0x2d05 for the holes and tee boxes. Also declared in these text files is the grid resolution. The defaults in the example Sample Map file generated a very jagged golf course map that he had to modify to get the look you see below. (A list of all of the codes is listed in the GPSmapper directory as a file called RGNtype.csv and a text file version called RGNtype.txt) Modify the GenerateMaps.bat file. This will invoke the command line version of the GPS Mapper utility. . At the same time, a Perl script that automatically generates both the text control file and Make file from the list of PLT anf WPT file would also be a worthy addition. But for now, let’s keep things simple. Batch file doesn't automatically invoke GPS Mapper. But you can run the program by hand and then load the image that you are interested in modifying. This will also allow labels/TRE's to be modified. The batch file creates two image files 10000012/13 respectively and a top level GOLFCOURSE.img/tdb. It is these two top level files that are used inside MapSource to navigate which maps needs to be downloaded without having to insert a CD.
Now Start MapSource, In MapSource highlight the region you wish to download to your GPS receiver. Connect you're GPS device to your PC and click "File/Send To Device".

Ok U may use the map edit for making map I think it will be more easy than ozi ...it continuous...at present U should better watch the video of how it works (mapedit) :
