Length of the Amazon River

With the help of satellite photography it should be possible to survey the length of the Amazon River anew after the source of Río Apurímac at Nevado Mismi has been confirmed as the river's true origin (instead of Río Marañón which had been believed to be the Amazon's source until the 1970s).

Using Google Earth, I have attempted to measure Río Apurímac from its source to the confluence with Río Mantaro in 25 km segments, and will do so with the other Amazon headwaters from Nevado Mismi to its mouth in the Atlantic Ocean.

I measured each 25 km segment in partial segments of 40 m (Google Earth elevation: 7,292 ft), and have specifications of latitude and longitude for each 25 km-stopover noted down below.

I ask all the Wikipedians to check the different segments and note down below where their length differs from my measurements. When you write down differing length, you might note them down this way: "Segment 175-200" (= Distance from Point 175 to 200)
