I have about 600 GeoTIFF map files, each about 140 mb in size that I'd like to convert to KMZ files so people can download them and use them with Garmin GPS units, Google Earth, etc.
Anyone know an easy way to batch process these, preferably converting the tiff image to a much smaller jpeg image as part of the process?
I've stumbled upon gdal_translate which I guess might be useful optimising the images into something smaller using the "-co COMPRESS=JPEG" option.
Answer
OkMap Desktop (full, paid for version) now includes a batch function for generating Garmin Custom Map compatible KMZ files, so I'm now using this.
