If your country does not have a high quality map offered by Google Maps, you could improve them by 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 regularly updates their Google Maps with data taken from Google Map Maker, but the changes are not taken immediately. To see the latest data from Google Map Maker add this layer to Google Maps.
Google Map Maker allows users to edit the maps for 174 countries because the maps licensed by Google aren’t detailed enough.
