GeometryCorrect (Function)

In french: GéométrieCorrige

Returns a corrected version of the specified geometry.

Remark: Some problems can be automatically corrected, such as misaligned points in a polygon.

Example

// Correct a triangle whose exterior ring is oriented 
// counterclockwise
triangle is Polygon2D
Linestring2DAddPoint(triangle.Outline, -3.00, 1.00)
Linestring2DAddPoint(triangle.Outline, 1.00, -2.00)
Linestring2DAddPoint(triangle.Outline, 2.00, 2.00)
Linestring2DAddPoint(triangle.Outline, -3.00, 1.00)
Trace("GeometryIsValid(triangle) = " + GeometryIsValid(triangle)) // False

// Correction
corrected_triangle is Polygon2D
corrected_triangle = GeometryCorrect(triangle)
Trace("GeometryIsValid(corrected_triangle) = " + GeometryIsValid(corrected_triangle)) // True
Trace("GeometryIsValid(triangle) = " + GeometryIsValid(triangle)) 
// Still False: the geometry passed as a parameter is not modified

Syntax

<Result> = GeometryCorrect(<Geometry>)

<Result>: Variable corresponding to the geometry

Corrected geometry.

<Geometry>: Variable containing spatial data

Potentially incorrect geometry to be corrected. This parameter is not modified by the function. This geometry can correspond to one of the following variable types:
PointGeo.
Point2D.
LinestringGeo.
Linestring2D.
PolygonGeo.
Polygon2D.
MultiPointGeo.
MultiPoint2D.
MultiLinestringGeo.
MultiLinestring2D.
MultiPolygonGeo.
MultiPolygon2D.
