This is not unexpected. It's fun to think that the plane/satellite is always exactly overheard when the shutter clicks and/or that all the imagery in Earth (or any similar program) is 100% orthorectified. As mobile computing devices become more and more prevalent and powerful, they are becoming more and more useful in the field of law enforcement investigations and forensics. I’m hoping to continue the above discussion on how to create accurate workable POI files considering the inherent flaws in GE / EPE, GPS position accuracy and user interpretation. https://productforums.google.com/d/topic/maps/6K294uFlRmU

How Accurate Is Google Earth Gps Coordinates

In my neighborhood, an exact geographic location shows up offset about 30 feet in Google Earth, or pretty much what we see in the picture above. Unfortunately, I’m not great at putting into words what I can clearly see in my mind but I’ll give it a shot. You are right, 10 feet off is excellent. That error is around 30 feet in most of North America.

For areas smaller than about 2 kilometres square, the error is usually of the order of a meter or two and can usually be neglected. Accuracy Of Google Earth I really get into this stuff and get carried away sometimes. So in areas of extreme topography, images won't be "stretched" properly to fit the terrain. http://www.gearthblog.com/blog/archives/2014/03/fix-errors-google-earth.html The compound effect caused by an error such as the one above would probably not be a serious issue when trying to create a waypoint for say a driveway entrance or

The result in Google Earth will be almost as accurate as the GeoPortal, with very small differences attributable to the resolution and hand-placement of the calibration move magnifier. I've seen imagery alignment problems on the order of 50 feet, more in Google Maps than in Google Earth; for some weird reason they seem to have different imagery or alignment. Bing Maps

AirPhoto does not correct for distortion in a Google Earth image but it does transform the calibration points at the corners and centre of the image to the ellipsoid of the The positions in Google Earth don't necessarily coincide with the correct position on Mother Earth. because I think that the stitching together of the images results in duplication and I chose the pole I thought was the real one with a transformer. useful reference This post has been edited by Grasscatcher: 08 April 2008 - 04:43 PM Back to top of the page up there ^ #4 OpenTrackRacer GPS Junkie Group: +Premium Members Posts:

BTW, I agree with the pole you chose. In this case, the image with the displaced calibration point is the sharpest of the three. I could take the "X marks the spot" coordinates from Google Earth in this case if I wanted to. this page Back to top of the page up there ^ #13 table/cache Geocacher Group: Members Posts: 24 Joined: 01-July 07 Posted 10 April 2008 - 10:23 AM I think it's telling
