I have a Garmin 64S GPS unit that I'd like to get a topographic basemap layer onto, so I'm not wandering with a blank screen while getting to my field sites for my research.
I'm using ArcMap 10.3.1, and I have a USGS topographic map that I'd like to download onto my GPS unit.
I've tried using Basecamp and Map Tiler software to get this topo onto my GPS via ArcMap, and I've also tried directly sticking it into a "CustomMaps" folder, but nothing has worked.
My GPS unit, which has the most recent software update, only accepts JPEGs for custom maps, which I've attempted to import to no avail.
I've called Garmin Customer Service, and they wanted me to georeference the .jpg via Google Earth, save it as a .kmz file, and then import it onto the GPS. Again, my GPS doesn't recognize .kmz files. I'm working with a GIS specialist, and we're both scratching our heads currently on how to do this.
Is it possible to take a topo from ArcMap and transfer it onto a GPS unit, or is that impossible?
