How accurate is the elevation data?

FBS March 5, 2020 Comments Off on How accurate is the elevation data?

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 on the ground compared to what’s shown in the digital file can be as great as 40 cm or 80 cm. The most accurate areas will be those with excellent ground visibility in the source orthophoto which the elevation model was derived from. Areas with dense forest, especially coniferous forest where the ground is obscured, tend to have the lowest accuracy.
