utmgeoid

Recommend geoids for Universal Transverse Mercator projection zone

Syntax

• geoid = utmgeoid 
  geoid = utmgeoid(zone)
  [geoid,geoidstr] = utmgeoid(...)
  

Background

The Universal Transverse Mercator (UTM) system of projections tiles the world into quadrangles called zones. Each zone has different projection parameters and commonly used ellipsoidal models of the Earth. This function returns a list of ellipsoid models commonly used in a zone.

Description

geoid = utmgeoid, without any arguments, opens the utmzoneui interface for selecting a UTM zone. This zone is then used to return the recommended ellipsoid definition(s) for that particular zone.

geoid = utmgeoid(zone) uses the input zone to return the recommended ellipsoid definition(s).

[geoid,geoidstr] = utmgeoid(...) returns the geoid string used by the almanac function.

Examples

• zone = utmzone(0,100) % degrees
  zone =
  47N
  
  [geoid,names] = utmgeoid(zone)
  geoid =
         6377.3     0.081473
         6377.4     0.081697
  names =
