I want to show a map of hikes within Washington state. For some I have GPS coordinates (and links to a Google Map), for others just the zip codes. Can I use both? If so, what are best practices for doing that? Thanks!
You can do this, but I'm not sure what you actually want to plot on the map. For example, do you wish to trail heads, plot actual trails turn-by-turn, sum up the number of trails within a particular area, other?
Can you provide an example data set and/or packaged workbook?
