Hi,

There is lots of info out there on how to create and/or convert jnx, img, kmz files but I can't find much on comparing the file types as they are used in the field. For example, suppose I have a selection of hiking trails in a google satellite photo in SASPlanet of a couple square miles with zoom= 20 or so.

Which file type should I create for my Oregon 600 and why? Why would I want to convert a jnx file to img? Etc...
