module RGeo::Feature::Point

SFS 1.1 Description

A Point is a 0-dimensional geometric object and represents a single location in coordinate space. A Point has an x-coordinate value and a y-coordinate value.

The boundary of a Point is the empty set.

Notes

Point is defined as a module and is provided primarily for the sake of documentation. Implementations need not necessarily include this module itself. Therefore, you should not depend on the kind_of? method to check type. Instead, use the provided check_type class method (or === operator) defined in the Type module.

Some implementations may support higher dimensional points.

Public Instance Methods

m() click to toggle source

Returns the m-coordinate for this Point as a floating-point scalar value.

This method may not be available if the point’s factory does not support M coordinates.

# File lib/rgeo/feature/point.rb, line 109
def m
  raise Error::UnsupportedOperation, "Method Point#m not defined."
end

x() click to toggle source

SFS 1.1 Description

The x-coordinate value for this Point.

Notes

Returns a floating-point scalar value.

# File lib/rgeo/feature/point.rb, line 74
def x
  raise Error::UnsupportedOperation, "Method Point#x not defined."
end

y() click to toggle source

SFS 1.1 Description

The y-coordinate value for this Point.

Notes

Returns a floating-point scalar value.

# File lib/rgeo/feature/point.rb, line 87
def y
  raise Error::UnsupportedOperation, "Method Point#y not defined."
end

z() click to toggle source

Returns the z-coordinate for this Point as a floating-point scalar value.

This method may not be available if the point’s factory does not support Z coordinates.

# File lib/rgeo/feature/point.rb, line 98
def z
  raise Error::UnsupportedOperation, "Method Point#z not defined."
