Detailed Description

vtFeatureSet contains a collection of features which are just abstract data, without any specific correspondence to any aspect of the physical world. This is the same as a traditional GIS file (e.g. ESRI Shapefile).

Examples: political and property boundaries, geocoded addresses, flight paths, place names.

Member Function Documentation

int vtFeatureSet::AddField	(	const char *	name,
		FieldType	ftype,
		int	string_length = `40`
	)

Add a data field to this featureset. The field contain a value of any type, for every entity.

Parameters

name	Name of the new field.
ftype	Type of the new field.
string_length	For backward compatibility with the old SHP/DBF file formats, this is the maximum length of a string, for string fields. It has no effect unless you save this featureset to a SHP/DBF file.

bool vtFeatureSet::AppendDataFrom ( vtFeatureSet * pFromSet)

Append the contents of another featureset to this one. The two featuresets must have the same geometry type. Only fields with matching names are copied in the record data.

int vtFeatureSet::GetFieldIndex ( const char * name) const

Return the index of the field with the given name, or -1 if no field with that name was found.

OGRwkbGeometryType vtFeatureSet::GetGeomType ( ) const

Returns the type of geometry that each feature has.

Returns

wkbPoint for 2D points
wkbPoint25D fpr 3D points
wkbLineString for 2D polylines
wkbPolygon for 2D polygons

bool vtFeatureSet::LoadDataFromCSV	(	const char *	filename,
		bool	progress_callbackint = `0`
	)

Load a featureset's field data from a comma-separated-value (CSV) file.

Parameters

filename	filename in UTF-8 encoding.
progress_callback	Provide a callback function if you want to receive progress indication.

Returns: true if successful.

bool vtFeatureSet::LoadDataFromDBF	(	const char *	filename,
		bool	progress_callbackint = `0`
	)

Load a featureset's field data from a DBF file

Parameters

filename	Filename in UTF-8 encoding.
progress_callback	Provide a callback function if you want to receive progress indication.

Returns: true if successful.

bool vtFeatureSet::LoadFieldInfoFromDBF ( const char * filename)

A lightweight alternative to LoadDataFromDBF, which simply reads the field descriptions from the DBF file.

bool vtFeatureSet::LoadFromSHP	(	const char *	fname,
		bool	progress_callbackint = `0`
	)

Load a featureset from a SHP (ESRI Shapefile).

Parameters

fname	filename in UTF-8 encoding.
progress_callback	Provide a callback function if you want to receive progress indication.

Returns: true if successful.

virtual void vtFeatureSet::Reserve ( int iNum)

pure virtual

If you know how many entities you will be adding to this FeatureSet, is it more efficient to reserve space for that many.

Implemented in vtFeatureSetPolygon, vtFeatureSetLineString3D, vtFeatureSetLineString, vtFeatureSetPoint3D, and vtFeatureSetPoint2D.

bool vtFeatureSet::SaveToKML	(	const char *	filename,
		bool	progress_callbackint = `0`
	)		const

Export a featureset to a KML file. This is still very limited and experimental.

Parameters

filename	Filename in UTF-8 encoding.
progress_callback	Provide a callback function if you want to receive progress indication.

Returns: true if successful.

bool vtFeatureSet::SaveToSHP	(	const char *	filename,
		bool	progress_callbackint = `0`
	)		const

Save a featureset from a SHP (ESRI Shapefile) with corresponding DBF file

Parameters

filename	Filename in UTF-8 encoding.
progress_callback	Provide a callback function if you want to receive progress indication.

Returns: true if successful.

void vtFeatureSet::SetGeomType ( OGRwkbGeometryType eGeomType)

Set the type of geometry that each feature will have.

Parameters

eGeomType

wkbPoint for 2D points
wkbPoint25D fpr 3D points
wkbLineString for 2D polylines
wkbPolygon for 2D polygons

void vtFeatureSet::SetNumEntities ( int iNum)

Set the number of entities. This expands (or contracts) the number of geometry entities and corresponding records.
