Map file from paper map

What is the easiest way to create a map file for a handheld Garmin Etrex 30 from a scanned paper map? This is a one off exercise.

Look above: Converting JNX to raster IMG

Thanks Giomen, but I as far as I can see that thread doesn't say how to get to a JNX file from a paper map?

@davee3,

Try this online link:

With MapTiler, it is quite simple to upload a custom map into your Garmin handheld GPS navigation. You can use any available raster online map or scan a paper map. In MapTiler choose Google Earth option

Spoiler: Online converter

This is the basic workflow to get to a JNX file from a paper map using the brilliant MAPC2MAPC software (you can try it before you buy it):

1. Scan the map to a jpg, jpeg, png file
2. Buy a copy of MAPC2MAPC map conversion software
3. Load your map jpg into MAPC2MAPC and calibrate (georeference) it
4. You can check the accuracy of the calibration by writing a the calibrated map to kmz format and checking it on Google Earth
5. If you are happy with the accuracy, write the map to a JNX file
6. Then convert your new JNX file to an IMG file using JNX2IMG

There is lots of information on this in this forum and on the MAPC2MAPC website etc

1. Scan the map to a jpg, jpeg, png file

Or use Mobac ===> OziExplorer (PNG & Map) for scanning the map

Yes that works fine if there is a working Custom Map Source to use with MOBAC for the mapping you want. The PNG and MAP files can be then loaded into MAPC2MAPC to write the JNX.
