Accuracy Of Ruler In Google Earth Pro?
Answer : I think that might be because there is no single, clear answer. I'll try to summarize my knowledge and the two most related questions: Google Earth, Google satellite, and Bing aerial accuracy How accurate are measurements in Google Earth? Let's start by taking Google Earth and even GIS out of the equation and only consider how accurate a measurement on an image can be. If the resolution of an image is a pixel is 1m, and you are zoomed in far enough to see individual pixels (original, not resampled for display purposes), you can measure to within +/- 1m. Now let's get that into GIS, which requires both orthorectification and georeferencing. Both can introduce error. On top of which, you're looking at errors introduced by (re)projection. Now let's put that all into Google Earth, which is providing you a seamless interface to multiple original sources. All of which may vary in their original resolution and quality of the above processes, so righ...
