Mapping with Google Map Maker

In last week’s post about the Ground Truth Project we told you how Google Map Maker is a key component of Google’s strategy to achieve more accurate maps – and keep them accurate. When Google introduced Map Maker to the public back in 2008, it was initially only available in a small number of countries, but over the years its has been made available in more and more places. The relevant Map Maker support page lists 227 countries or locations where it is now available. Some of the few remaining countries not yet covered are: Colombia, Chile, Argentina, Ireland, Portugal, Spain, Turkey, China, Thailand, Indonesia, South Korea and Japan.

Zambia is one of those countries where the Ground Truth Project has not yet got to, so its maps depends almost entirely on Map Maker. I was recently asked by my sister, who lives in Livingstone, Zambia, if I would update some street names in Google Earth. The streets are in a fairly new development, and the local council has recently put up some street signs, so she wrote down the names of some of the streets and sent them to me.

When I first used Google Map Maker, every edit had to be reviewed by someone else before it went live, but over time, I have been allowed to make some changes without them waiting for review. So when I added street names to roads that were unnamed, the changes were reflected in Google Maps immediately. However, a few of the roads were not in Google Maps, so I had to add the roads as well as name them and this had to be reviewed, which took about a week. As you can see below there are still a lot more streets without names, so perhaps next time I am in Livingstone I will go around and collect the names of all unlabeled streets that do have street signs, or perhaps I will ask the local City Council if they can give me an official map.

Google Maps After Update

One interesting thing I have noticed though is that although the streets show in Google Maps immediately, they cannot be found when doing a search. Other streets nearby do show up in search results, including ones that I have personally added the names for in the past. I am guessing that it takes a while for new additions to get into the search database.

If one of our readers is a Map Maker aficionado, maybe they can let us know if this is a correct guess, and if so, how long it typically takes to for names to get into search.

It used to be the case that changes made in Map Maker would eventually filter through to Google Earth. However, I corrected the name of a major road (Airport Road) in that area in January of this year and it still shows the old name in Google Earth (Libala Drive). However if you search for ‘Airport Road’ in Google Earth, it finds the correct road.

Comments

  1. Do you know when will Google Map Maker be available again for ARGENTINA, COLOMBIA, etc?

    • Timothy Whitehead says:

      No, I am afraid I do not know. Google has been expanding the number of countries covered by both Map Maker and the Ground Truth Project over time, so it is likely coverage for both will continue to be expanded. The Ground Truth project however depends quite heavily on Street View, so Google generally does not start to use it in a country until it has Street View in that country.

  2. Now Indonesia have street view but still no Google Map Maker.

  3. You would do well to include your naming of streets on OpenStreetMap also seeing as anyone can access the raw geo data of OpenStreetMap to use in applications and GIS software, specifically in the case of Zambia, aid agencies and NGO’s
