There is not really any way to save the two together. You can save the annotations separately in a KML file using the "KML of Annotations" link. That KML file can then be viewed in Google Earth or lots of other softwares. The GeoTiff and KMZ files can also be viewed easily in other software.
There is no way to save the combined Location Map without some manual merging work with external software. We recommend downloading all of the GeoTiff files and then using QGIS to do a raster merge on them (combine them). The Location Map can be shared in web map form using the public links or the iFrame embed codes just like single layer maps.
