I don't have a GPS
Navigator in my car,and frequently got lost
while driving in the megacity of Sao Paulo. I thought,Hey... why not use OCPN,create appropriate maps from Google
Maps and convert to .kap suitable for OCPN. I also easily found a suitable car icon with a view from above,converted with GIMP II and added to the UserIcons directory. I also purchased a cheap
Dlrs 40.- puck
In order to capture a road map of adequate size,I used the free NoniMap View program where you have a selection of different map formats and can create outsize maps in great detail. After the map is ready built and saved,make a note of the map co-ordinates displayed at the top left of the NoniMap screen
. It shows the geo locs of the Top left and Bottom right of the created map.
Use free MapCal II to create the CHARTCAL.DIR calibration file,having first prepared the .jpg map in GimpII to 127 col. and save to your GE2KAP directory as a .png file.
The rest is done by GE2KAP by entering the name of the .kap file,making sure that the CHARTCAL.DIR file is also present in the same directory. After processing in GE2KAP you will have a .kap map of your selected area which you save to the OCPN map area. You also have to alter the name of your car.xpm file to ownship.xpm and re-set OCPN.
Then jump backwards through four burning hoops and you should be ready! he he...
