Is it possible to use google maps like this?

Question

Google

I need to allow users on the site to be able to point to a specific location on a google map loaded in an iframe.

I decided to make 2 fields corresponding to the coordinates that can be obtained on the google maps website .

Those. the user follows the link https://www.google.ru/maps , selects a place on the map, clicks on it, gets the coordinates and inserts it into the fields on the site. And I, in turn, substitute these values ​​in the download link of the iframe . It turns out that I'm using the Google iframe , but with my own coordinates.

I read the terms of use of google maps , they do not write about this there. Is it possible to do so?
