DO.COM.06 GeoShape

The spdci:GeoShape object represents complex geographical features

The spdci:GeoShape enables the representation of complex geographical features and areas in a structured, machine-readable format, useful in various applications that require spatial awareness and precise geographical data.

Property Key	Data Type (and Restrictions)	Cardinality	Description
box	DT.COM.02 string	0...1	A rectangular area on a map via two geographical points: the lower and upper corners
circle	DT.COM.02 string	0...1	A circular region with a defined radius, centered at a given latitude and longitude, expressed as a pair followed by a radius in metres
elevation	DF.COM.STRING.03 distance	0...1	Elevation of a location (WGS 84)
line	DF.COM.STRING.05 geo_line	0...1	A point-to-point path defined by two or more points, expressed as a series of point objects separated by space
polygon	DF.COM.STRING.06 polygon	0...1	Encloses an area with a point-to-point path, where the starting and ending points are identical, expressed as a series of four or more space-delimited points, with the first and final points being identical

    "circle": "33.3128,44.3615 2000",
    "elevation": "34 m",
    "line": "33.3128,44.3615 33.5138,44.5535",
    "polygon": "33.3128,44.3615 33.5138,44.5535 33.4128,44.4515 33.3128,44.3615"
}

In this example, the spdci:geo_shape instance describes various geometrical shapes on a map, illustrating a box, a circle, a line, and a polygon, each defined with its respective properties. The elevation property indicates the height above sea level, represented here in meters.
