WindBarbStyle¶
Namespace: ThinkGeo.Core
Draws wind barbs for point features by parsing their METAR description and converting wind speed to knots.
public class WindBarbStyle : Style
Inheritance object → Style → WindBarbStyle
Properties¶
WindDirectionAngleColumnName¶
Gets or sets the column name containing the wind direction angle in degrees.
public string WindDirectionAngleColumnName { get; set; }
Property Value¶
WindSpeedInKnotsColumnName¶
Gets or sets the column name containing the wind speed expressed in knots.
public string WindSpeedInKnotsColumnName { get; set; }
Property Value¶
DrawingLevel¶
Gets or sets the drawing level at which the barbs are rendered.
public DrawingLevel DrawingLevel { get; set; }
Property Value¶
SymbolSize¶
Gets or sets the size, in pixels, of the wind barb symbol.
public float SymbolSize { get; set; }
Property Value¶
Pen¶
Gets or sets the pen used to stroke the wind barb.
public GeoPen Pen { get; set; }
Property Value¶
Brush¶
Gets or sets the brush used when filling the triangular pennants.

Parameters¶
features IEnumerable<Feature>
