Detailed Description

The QgsOgcUtils class provides various utility functions for conversion between OGC (Open Geospatial Consortium) standards and QGIS internal representations.

Currently supported standards:

GML2 - Geography Markup Language (import, export)

Member Function Documentation

QColor QgsOgcUtils::colorFromOgcFill ( const QDomElement & fillElement )

static

Parse XML with OGC fill into QColor.

Definition at line 1405 of file qgsogcutils.cpp.

QgsExpression * QgsOgcUtils::expressionFromOgcFilter ( const QDomElement & element )

static

Parse XML with OGC filter into QGIS expression.

Definition at line 1444 of file qgsogcutils.cpp.

QDomElement QgsOgcUtils::expressionToOgcFilter	(	const QgsExpression &	exp,
		QDomDocument &	doc,
		QString *	errorMessage = `0`
	)

static

Creates OGC filter XML element.

Supports minimum standard filter according to the OGC filter specs (=,!=,<,>,<=,>=,AND,OR,NOT)

Returns

valid

<Filter>

QDomElement on success, otherwise null QDomElement

Definition at line 1889 of file qgsogcutils.cpp.

QgsGeometry * QgsOgcUtils::geometryFromGML ( const QString & xmlString )

static

static method that creates geometry from GML

Parameters

xmlString

xml representation of the geometry. GML elements are expected to be in default namespace (

{<Point>...</Point>

) or in "gml" namespace (

<gml:Point>...</gml:Point>

)

Definition at line 81 of file qgsogcutils.cpp.

Definition at line 20 of file qgsogcutils.cpp.

QDomElement QgsOgcUtils::geometryToGML	(	QgsGeometry *	geometry,
		QDomDocument &	doc,
		QString	format,
		const int &	precision = `17`
	)

static
