Geoid height
Compute geoid height using the geoid models SWEN08_RH2000 and SWEN08_RH70. Enter the latitude and longitude in SWEREF 99.
SWEN08_RH2000
Enter coordinates in SWEREF 99:
Result
Geoid height: (metres)
SWEN08_RH70
Enter coordinates in SWEREF 99:
Result
Geoid height: (metres)
Description
Today it is becoming increasingly more common that satellite techniques are used for positioning. This results in heights relative to a reference ellipsoid. To convert the height above the ellipsoid, h, to the height above sea level, H, the separation between these two surfaces must be known. This separation is called the geoid height N; see the figure and the equation below.
h = H + N
SWEN08_RH2000 is a geoid model that is adapted to SWEREF 99 and the height system RH 2000. SWEN08_RH70 is the corresponding model for SWEREF 99 and the older height system RH 70. More information about the geoid models can be found under the pages of the geoid.
