Detailed Description

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

Currently supported standards:

Member Function Documentation

QColor QgsOgcUtils::colorFromOgcFill ( const QDomElement &  fillElement)
static

Parse XML with OGC fill into QColor.

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

Parse XML with OGC filter into QGIS expression.

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

static method that creates geometry from GML

Parameters
xmlStringxml representation of the geometry. GML elements are expected to be in default namespace (
{<Point>...</Point> 
) or in "gml" namespace (
<gml:Point>...</gml:Point> 
)
QgsGeometry * QgsOgcUtils::geometryFromGML ( const QDomNode &  geometryNode)
static

static method that creates geometry from GML

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

Exports the geometry to GML2 or GML3.

Returns
QDomElement
QDomElement QgsOgcUtils::geometryToGML ( QgsGeometry geometry,
QDomDocument &  doc,
const int &  precision = 17 
)
static

Exports the geometry to GML2.

Returns
QDomElement
QgsRectangle QgsOgcUtils::rectangleFromGMLBox ( const QDomNode &  boxNode)
static

read rectangle from GML2 Box

QgsRectangle QgsOgcUtils::rectangleFromGMLEnvelope ( const QDomNode &  envelopeNode)
static

read rectangle from GML3 Envelope

QDomElement QgsOgcUtils::rectangleToGMLBox ( QgsRectangle box,
QDomDocument &  doc,
const int &  precision = 17 
)
static

Exports the rectangle to GML2 Box.

Returns
QDomElement
QDomElement QgsOgcUtils::rectangleToGMLEnvelope ( QgsRectangle env,
QDomDocument &  doc,
const int &  precision = 17 
)
static

Exports the rectangle to GML2 Envelope.

Returns
QDomElement
