I would like to ask if someone could point me in the right direction.
I need a UTM grid (1x1km) layer in Garmin handheld GPS, so the UTM grid would show on top of the map. The grid layer should be on/off switchable in map selection in Garmin. In order to be on/off switchable, it would have to be .img format.
Any ideas on what SW to use to generate the UTM grid and what format so it could be converted into .img? Or ideály, saved in .img right away. The UTM grid does not have to be for the whole world, just one country (33/34 U).
Model: Garmin Alpha 100/200i
