Member Function Documentation

virtual bool makVrv::DtWktHeaderParser::isValid ( )

virtual

Returns true if the file was loaded and produced acceptable coordinate system information and origin information.

Implements makVrv::DtHeaderParser.

virtual bool makVrv::DtWktHeaderParser::getWktString ( std::string & wktString )

protectedvirtual

Returns true if the WKT string was found, the string being placed in wktString.

virtual bool makVrv::DtWktHeaderParser::checkLz4Medf	(	std::fstream &	f,
		std::string &	decompressedString
	)

protectedvirtual

check for an Lz4 Medf and get the decompressed version of the file if it is. returns true if it is an Lz4 Medf.

virtual bool makVrv::DtWktHeaderParser::decompressLz4	(	std::istream &	fin,
		std::string &	target
	)

protectedvirtual

takes in a stream and decompresses the lz4. used for MEDF 1.2.

virtual bool makVrv::DtWktHeaderParser::findWktString	(	std::istream &	f,
		std::string &	wktString
	)

protectedvirtual

takes in a stream and finds the wkt string if it exists.

virtual bool makVrv::DtWktHeaderParser::getOrigin	(	const std::string &	originLabel,
		double &	val
	)

protectedvirtual

Returns true if the specified origin value was found, the origin value being placed in val.

virtual bool makVrv::DtWktHeaderParser::findOrigin	(	std::istream &	decompressedStream,
		const std::string &	originLabel,
		double &	val
	)

protectedvirtual

takes in a stream and finds the origin string if it exists.

virtual bool makVrv::DtWktHeaderParser::parseWktString	(	const std::string &	wktString,
		double	xOrigin,
		double	yOrigin
	)

protectedvirtual

Returns true if the WKT string yields an appropriate coordinate system.

virtual bool makVrv::DtWktHeaderParser::parseGeocentric	(	const OGRSpatialReference &	spatialRef,
		double	xOrigin,
		double	yOrigin
	)

protectedvirtual

virtual bool makVrv::DtWktHeaderParser::parseLambert	(	const OGRSpatialReference &	spatialRef,
		double	xOrigin,
		double	yOrigin
	)

protectedvirtual

virtual bool makVrv::DtWktHeaderParser::parseUtm	(	const OGRSpatialReference &	spatialRef,
		double	xOrigin,
		double	yOrigin
	)

protectedvirtual

virtual bool makVrv::DtWktHeaderParser::parseFlat	(	const OGRSpatialReference &	spatialRef,
		double	xOrigin,
		double	yOrigin
	)

protectedvirtual

virtual bool makVrv::DtWktHeaderParser::convertCoordinates	(	const OGRSpatialReference &	spatialRef,
		double	x,
		double	y,
		double &	convX,
		double &	convY,
		bool	inDegrees
	)

protectedvirtual

Converts a point to the latitude and longitude of the corresponding point in the coordinate system.

virtual bool makVrv::DtWktHeaderParser::usingDegrees ( const OGRSpatialReference & spatialRef )

protectedvirtual

Returns true if the coordinate system parameters are specified in degrees instead of radians.
