Open hard surface data is accurate to 10cm at 95%. If the surface is not hard, it all depends on the surface, but at least twice the hard surface accuracy would be a good place to start.

Where to start? The process below should help you decide what kind of aerial imagery you need and how to acquire it. You’ve got a few choices of satellite and aerial orthophoto. Answering a few ques...

It depends on the photo resolution. Whatever the stated photo resolution in cm, positional accuracy is double that value. A 15 cm photo, for example, has positional horizontal accuracy of +/- 30 cm. T...

The orthophoto are generally spatially accurate to double the resolution value. Simply put, if a photo has resolution of 20cm, any point on the photo will be accurate within 40 cm of its true location...

In the 2002 Golden Horseshoe data set, the horizontal and vertical accuracy is +/- 40 cm, and +/- 80 cm for the 2002 Simcoe-Kawartha data set. This means that the difference between the true elevation...
