If Google Maps doesn't offer high-quality maps for your country, you can improve them using Google Map Maker. "Google Map Maker allows you to create a map by adding or editing features such as roads, businesses, parks, schools and more. Using Google Map Maker tools, you can visually mark locations and add detailed information about them. Once you have submitted content, this information may be edited by other users or moderators. Your mapping contributions on Map Maker are eventually also made available on Google Maps," explains Google.
Google constantly updates Google Maps with data from Map Maker, but the changes aren't reflected immediately. To see the latest data from Google Map Maker, add this layer to Google Maps.
Google Map Maker lets you edit the maps for 174 countries because the maps licensed by Google aren't detailed enough.
