Describes an angle in GIS.

    typedef struct {
        double     angleDouble;
        short      angleDeg;
        short      angleMin;
        short      angleSec;
        char       hemiLetter;
        char       filler_1;
    } API_GISAngular;

 

Members

angleDouble

Double precision angle, used for not whole values

angleDeg

Degree (if it is a whole number)

angleMin

Minutes (if it is a whole number)

angleSec

Seconds (if it is a whole number)

hemiLetter

Hemisphere abbreviation letter, can be : ‘N’ ‘S’ ‘E’ and ‘W’

 

Remarks

It holds the angle as you have put it, the stored values will not be changed nor converted. All the members are not used in every case, the coordinate system’s angleUnit field shows which members will be used (see also: GISAngularUnit).

This structure is used in API_GISAngularPos, API_GISAngleRef and API_GISMapProjectionParam.

 

Requirements

Version: API 6.1 or later
