Of course! :) Dividing is the easy part:
- If you have some plus code (for example of length 8, *66FF88XX+*), you can replace pairs of characters with '0' to get another plus code for a larger area that contains the original area: *66FF8800+*, *66FF0000+*, *66000000+* - Likewise, if you have a plus code for a larger area (say, *66FF8800+*), you can generate the codes for all 20x20 sub-blocks simply by iterating through all possible pairs of code characters (*"23456789CFGHJMPQRVWX"*) and replacing the '0' characters with that: *66FF88**22+* *66FF88**23+* *66FF88**24+* *...* *66FF88**2X+* *66FF88**32+* *...* *66FF88**XX+* Now, finding out which of these code areas overlap with your feature can be a bit more tricky, depending on how you've defined your feature. For purely geometrical definitions of the feature (like origin/radius of a circle, or polygon), the best approach might be to look at various intersection algorithms. For other, more arbitrary definitions (like "surface area of $city"), other approaches might work better. In any case, the important thing to keep in mind here is the fact that the area of any plus code is simply a box aligned with the latitude/longitude grid, with just four important values (minimum/maximum latitude, minimum/maximum longitude).
