Lines and polygons

Polylines and polygons can be used on a static map to mark a route or the boundaries of an object.

A polyline consists of a set of points connected by straight line segments. A polyline can cross itself. If the coordinates of the first and last points are the same, the polyline is called a closed polyline.

A polygon is set using one or more closed polylines.

Restriction. The Static API allows displaying no more than 5 polylines and polygons on a map at once, and the total number of points on figures cannot be more than 100.

The outward appearance of a geometric figure is set using a special definition. The polyline definition contains information about the thickness and color of lines, while the polygon definition contains information about the thickness and color of the outline and the fill color (see below).

The points on all figures are assigned geographical coordinates.

The point coordinates and the outward appearance of polylines and polygons are set using the pl parameter. This parameter contains definitions for all the figures displayed on the map. Figure definitions are separated by a tilda (~):

pl = FigureDefinition1~FigureDefinition2~FigureDefinition3

The polyline definition has the following format:

c:{line color},w:{thickness},{points}

The polygon definition can additionally contain the fill color (the f parameter):

c:{line color},f:{fill color},w:{thickness},{points}

Line color

Hexadecimal representation of the line color in RGBA format (such as 0xFFFFFFFF). The first 6 characters set the RGB color, and the last two set the transparency of the line. The transparency value is in the range from 00 (transparent) to FF (opaque).

For example:


Polygon fill color

Uses the same format as the polyline color (see above). For example:


The even-odd rule is used for filling a polygon. This means that a point is filled in if a ray drawn from that point to infinity has an odd number of intersections with the edges of the polygon.

An area where several polygons intersect is always filled in.


Line thickness (in pixels).

Note. If color and thickness are not set, a light violet semitransparent line with a thickness of 5 pixels is used (8822DDC0).


The coordinates of the polyline vertices are defined in the following way: Longitude1,Latitude2,...,LongitudeN,LatitudeN.

The point coordinates of a polygon formed by a single closed polyline (where the first and last point coincide) are set in the same way.

To define a polygon using a set of closed polylines, a semicolon must be used to separate the sequence of points for each polyline: CoordinatesOfPolyline1Vertices;...CoordinatesOfPolyline2Vertices.



The following example requests a section of the map of Izmir showing the route from the Çankaya metro station to the building of Turkiye Tarim Kredi Kooperatifleri. The polyline points are set by a list of point coordinates, and the default color and thickness are used:,38.422478,27.137685,38.422469,27.137736,38.422564,27.137789,38.424045,27.138519,38.423975,27.141899,38.423802,27.142215,38.423756,27.142333,38.423697,27.142376,38.423549,27.142596,38.423368,27.142971,38.423347,27.143285,38.423625,27.143245,38.423912,27.143015,38.424102,27.142795,38.424128,27.142795,38.424128,27.142387,38.423918,27.141909,38.423918,27.138275,38.42422

Polygon defined by a single polyline

The example below shows a request for part of the map of Izmir showing the boundaries of the walls of İzmir Fuarı. It uses a polygon with a red outline and light green semitransparent fill to define the boundaries of the fortress:,f:00FF00A0,w:7,27.14325,38.43178,27.14855,38.430419,27.149794,38.428225,27.147327,38.425693,27.147305,38.424562,27.143142,38.424089,27.141426,38.427853,27.14325,38.43178

Polygon defined by a set of polylines

The example below is for a map that displays a polygon defined by a set of polylines. The polyline point coordinates are separated by a semicolon.,w:7,29.085258,41.018105,29.100278,41.016024,29.097618,41.007508,29.086545,41.009978,29.085258,41.018105;29.089893,41.014724,29.096759,41.013814,29.096158,41.010303,29.091009,41.011669,29.089893,41.014724

Intersecting polygons

The example below is for a map that displays two intersecting polygons. The set of parameters for each polygon is separated by a tilda (~).

The area where the polygons intersect is always filled in.,c:003399,29.088504,41.052278,29.097001,41.042141,29.08756,41.044935,29.088504,41.052278~c:00ff0055,f:3caa3c77,29.100434,41.048444,29.086187,41.04643,29.089791,41.042076,29.100434,41.048444
