Why does Google Maps show two different distances?
The Google Maps Distance Matrix API does not calculate a straight-line or big-circle distance between two points. Instead it returns the distance according to the mode of travel (which you haven't specified in your API call, so it defaults to driving ).
Is Waze always accurate?
Real-Time Data. Though it's unknown exactly how much data is shared between the two apps, Waze and Google Maps are known to collect real-time traffic data from users who are already on the road. Because of this, both apps do provide accurate directions that take into account traffic jams, major road closures, and more.
Is it good to measure short distances?
Measuring short distances is typically pretty good, but longer the distance, the more sources of inaccuracies creep in. For example the longer the distance the more the effect of the curvature of the earth has an effect, Google Maps may model the earth as a sphere, but in reality its not a perfect sphere. Similly differences in altitude add ...
Does Google Maps have 100% accuracy?
Google has all that is required to calculate a distance to 100% accuracy. You have a Map to a scale that is 100% accuracy,presumably. You have a user defined route with waymarks and more than enough computing power to calculate the distances between the waymarks to 100% accuracy based on the scale you have.
Does Google have a proprietary format?
All imagery sources are fused into a single global database with a proprietary format that has been developed for the specific purpose of streaming to our client software. Cheers, ERC.
Does Google Earth have accuracy?

Distance between two points on a sphere
To measure the distance between two points of the map this ruler uses a formula that is more accurate than the Pythagorean theorem, because it measures the distance between two points on a sphere using Trigonometry. It is more accurate than assuming that the Earth is flat, but it's not perfect beacuse the Earth isn't a perfect sphere.
Google’s Position
- In 2009, a Google representative said: So Google says that coordinates may only be accurate to 15 meters? Holy cow, that’s not so fabulous. Let’s see what the scientific researchers have to say . . .
Scientific Research
- Benker, Langford and Pavlis (2011)investigated accuracy in the Big Bend region of Texas. These academic researchers say: Mohammed, Ghazi, Mustafa (2013)examined Google Earth in the Khartoum State of the Sudan and say: Ubukawa1 (2013)evaluated Google Earth in 10 cities around the world and found: So to summarize, the scientists are saying that longitude and latitu…
What Does It All Mean?
- Now I understand why I sometimes see property lines in Google going through the middle of driveways, roofs, golf courses, etc! Given the possible inaccuracy you may find that coordinates are still useful, but only for some purposes and not for others. Personally, I would use Google Maps longitude and latitude estimates in the following situations: 1. Locating the land corners s…
Conclusion
- The coordinates in Google Maps could be off by several meters (or yards). Google Maps is a great free resource when used wisely.
