Geometry.getProperty Function

Format

s = geometry_name.getProperty(property_name);

Description

The Geometry.getProperty function returns a string containing the current value associated with the Geometry object's property specified by the string expression property_name. If a Geometry object contains multiple features, the function returns the value of the first feature that contains a value for property_name. Property names are case sensitive.

Property values may be set using the Geometry.setProperty function. When reading a GeoJSON file using the Geometry.load function, property names and values are read from the properties section of GeoJSON features.

Return Value

The function returns a string with the property information. If no feature in the geometry has a value for the property, a blank string is returned.

Example

// Load geometry from a file
Geometry geom;
geom.load("geom.geojson");

// Read the name property
string feature_name = geom.getProperty("name");

errmsg("This feature is named %s", feature_name);
