Usage

Geometry, lines and shapes

Define a point on a map:

// Initialize a new point by latitude and longitude
IPoint point = new Point(55.708151, 9.536131);

Calculate the distance between two points:

// Initialize the points by latitude and longitude
IPoint a = new Point(55.708151, 9.536131);
IPoint b = new Point(55.708069, 9.536000);

// Calculate the distance in metres
double distance = DistanceUtils.GetDistance(a, b);

Define a line on a map:

// Initialize the points by latitude and longitude
IPoint a = new Point(55.708151, 9.536131);
IPoint b = new Point(55.708069, 9.536000);

// Initialize a new line from the two points
ILine line = new Line(a, b);

// Get the length of the line
double length = line.GetLength();

Define a line string (polyline) on a map:

// Initialize the points by latitude and longitude
IPoint a = new Point(55.708151, 9.536131);
IPoint b = new Point(55.708069, 9.536000);
IPoint c = new Point(55.708061, 9.536172);

// Initialize a new line string from the multiple points
ILineString line = new LineString(a, b, c);

// Get the length of the line string
double length = line.GetLength();

Define a polygon on a map:

// Initialize the points by latitude and longitude
IPoint a = new Point(55.708151, 9.536131);
IPoint b = new Point(55.708069, 9.536000);
IPoint c = new Point(55.708061, 9.536172);
IPoint d = new Point(55.708145, 9.536222);

IPoint f = new Point(55.708113, 9.536086);

// Initialize a new polygon from the multiple points
IPolygon polygon = new Polygon(a, b, c, d, a);

// Get the circumferences of the polygon
double circumference = polygon.GetCircumference();

// Get the area of the polygon
double area = polygon.GetArea();

// Get the bounding of the polygon
IRectangle bbox = polygon.GetBoundingBox();

// Does the polygon contain point "f"?
bool contains = polygon.Contains(f);
