Topography and Land Usage

Elevation

Gives the elevation in meters above sea level. The horizontal resolution is approximately 90 meters.

elevation:m

Examples

  • The depicted area is located in the Swiss canton "Wallis" and its most famous mountain, the "Matterhorn", is encircled in the right image. A terrain map of the corresponding region is also shown for more intuitive comparison (Map data: Google, August 2017).

  • To obtain the data in a different output format, just replace the format parameter in the URL by one of the following: csv, json, xml, png, html, netcdf, grads.
    Here is an example for the csv format:

Topography Deviation

The deviation in topography of the specified weather model compared to the NASA SRTM measured elevation.

Land Usage

Examples

Roughness Length

Roughness length of the ground, depending of the land usage. Roughness length is a parameter of some vertical wind profile equations that model the horizontal mean wind speed near the ground; in the log wind profile, it is equivalent to the height at which the wind speed theoretically becomes zero.

roughness_length:m

Shadow

This parameter returns 1 or 0 depending on whether the coordinate is in shadow of the topography at the specified time or not.
