Detailed Description

Class provides operations with 2D seismic data for UNIVERS db

Member Typedef Documentation

typedef std::pair<size_t, size_t> UDBSeis::Ranges

Indexies ranges.

Member Enumeration Documentation

enum UDBSeis::OSType

Type of observation system

Constructor & Destructor Documentation

UDBSeis::UDBSeis

(

)

Construct empty object. Non actual traces from db are skipped by default.

virtual UDBSeis::~UDBSeis ( )

virtual

Destructor, removes internal seismic data.

Member Function Documentation

void UDBSeis::addHdrAttr ( Trace::Header::AttrId  id )

inline

Add header attribute to be loaded.

void UDBSeis::clearHdrAttrsList ( )

inline

Clear header attributes list.

void UDBSeis::close

(

)

Close opened seismic data

bool UDBSeis::dbFill	(	const char *	project,
		const char *	name
	)

Fill object with db access from provided project and file name.

int UDBSeis::getComps

(

std::vector< char > &

comps

)

Get components list. Return number of components or negative value on error.

bool UDBSeis::getCoords	(	int &	ix,
		int &	iy,
		double &	ixl,
		double &	iyl,
		double &	izl
	)		const

Get coordinates of current SP,RP or CMP. Return false on errors (e.g. current type is EQL)

Parameters

ixl	Land coordinates
izl	Local coordinates

int UDBSeis::getMagnitograms

(

std::vector< int > &

nmgls

)

Get number of magnitograms and its indexies for current seismic type. Return number of magnitograms or negative value on any error.

std::string UDBSeis::getModName ( )

inline

Return name of current loaded modification

int UDBSeis::getOffsets

(

std::vector< int > &

offsets

)

Get uniq offsets, return number of uniq offsets or negative value on error.

int UDBSeis::getSamplesCount

(

)

const

Get number of traces samples in current selection, <0 if undefined.

Type UDBSeis::getSeisType ( ) const

inline

Get seismic type

double UDBSeis::getTbeg

(

)

const

Return begin time of traces

double UDBSeis::getTend

(

)

const

Return end time of traces

double UDBSeis::getTimeStep

(

)

const

Get traces time step in current selection, <0 if undefined.

TrSet& UDBSeis::getTrSet ( )

inline

Get set of traces with current selection from db directly, for hackers only.

bool UDBSeis::getWavefield	(	WaveField &	wf,
		Ranges *	pranges = 0x0
	)		const

Construct wavefield with current selection, return false on error. New traces will be added if provided wavefield not empty. If pranges provided it will contains id of the first trace and id of the trace after the last trace in required seismogram. All other traces in resulted wavefield may be taken from neighbour seismograms (see min traces_num in Type.)

bool UDBSeis::getWavefieldHeaders

(

TrHeader *&

headers

)

const

Get headers with current selection from db directly, for hackers only.

bool UDBSeis::getWavefieldSize

(

int &

wf_size

)

const

Return wavefield size (traces count) for current selection, return false on error.

bool UDBSeis::setSeisType

(

const Type &

type

)

Set seismic type, traces will be sorted by L
