Probably not
The Google Maps/Google Earth Additional Terms of Service section 2 b reads:
you may not (or allow those acting on your behalf to): ...
copy the content (unless you are otherwise permitted to do so by the Using Google Maps, Google Earth, and Street View permissions page or applicable intellectual property law, including "fair use");
and the Google Maps Platform Terms of Service section 3.2.3 reads:
(b) No Caching. Customer will not cache Google Maps Content except as expressly permitted under the Maps Service Specific Terms.
...
(f) No Circumventing Fees. Customer will not circumvent the applicable Fees.
However you are specifically allowed to "create KML files and map layers;" if that will satisfy your needs.
I don't find anything under the "Maps Service Specific Terms" that seems to explicitly allow the sort of storage you describe. So unless it is covered by fair use, or a similar exception to copyright, it would not be permitted. Fair use analysis requites more information about the specific use than is contained in the question, so i cannot asses that. Some countries have an exception to copyright for "personal use" but it is generally limited in some way. Without knowing what country the use would be in, and probably knowing more details about the use, That cannot be reliably analyzed either.
