The output from Spatial Calculator depends on the type of calculation.
Area
This operation returns the area of the geometry, in the units specified (output type is double).
Buffer
This operation returns a geometry representing the buffered shape.
Convex Hull
This operation returns a geometry representing the shape with a convex hull calculation applied.
Coordinate System Transform
This operation returns a geometry in the coordinate system specified.
Create Line Geometry
This operation returns a line geometry.
Create Point Geometry
This operation returns a point geometry (output type is double).
Create Polygon
This operation returns a polygon.
Difference
This operation returns the geometry portions of the first geometry that are not common with the second geometry. The resulting geometry is what remains of the first geometry after the second has been removed.
Distance
This operation returns the distance in the units specified (output type is double).
Distance To Edge
This operation returns the geographic distance between two geometries in the units specified (output type is double).
Envelope
This operation returns a geometry
Envelope Coordinates
This operation returns the latitude/longitude coordinates for the lower left and upper right corners of the envelope (output type is double).
From GeoJSON
Converts the specified GeoJSON string to a Spectrum Spatial geometry instance.
From KML
Converts the specified KML string to a Spectrum Spatial geometry instance.
From WKT
Converts the specified WKT string to a Spectrum Spatial geometry instance.Get Centroid
This operation returns the coordinates of the centroid of the geometry object (output type is double).
Intersection
This operation returns one or two kids of information:
- Geometry—The geometry of the area of intersection
- Percentage overlap—The percentage of the first geometry that overlaps with the second. This information is only returned if you choose to return it (output type is double).
Is Intersection
Returns "Y" if the two geometries intersect and "N" if they do not.
Is Line
Returns "Y" if the geometry is a line and "N" if it is not.
Is Point
Returns "Y" if the geometry is a point and "N" if it is not.
Is Polygon
Returns "Y" if the geometry is a polygon and "N" if it is not.
Is Valid Geometry
Returns a Boolean value indicating whether the supplied geometry is valid according to the geometry type.
Is Within
Returns "Y" if the first geometry is contained within the second and "N" if it is not.
Length
Returns the length of the geometry in the units specified.
Perimeter
Returns the length of the perimeter in the units specified.
Symmetric Difference
Returns the symmetrical difference of the two supplied geometries (that part of both geometries that do not intersect).
To GeoJSON
