Detailed Description

read a digital elevation model (DEM) file

vtkDEMReader reads digital elevation files and creates image data. Digital elevation files are produced by the US Geological Survey. A complete description of the DEM file is located at the USGS site. The reader reads the entire dem file and create a vtkImageData that contains a single scalar component that is the elevation in meters. The spacing is also expressed in meters. A number of get methods provide access to fields on the header.

Member Function Documentation

static vtkDEMReader* vtkDEMReader::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkAlgorithm.

virtual const char* vtkDEMReader::GetClassName ( ) [virtual]

Reimplemented from vtkImageAlgorithm.

static int vtkDEMReader::IsTypeOf ( const char * name ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageAlgorithm.

virtual int vtkDEMReader::IsA ( const char * name ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageAlgorithm.

static vtkDEMReader* vtkDEMReader::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkImageAlgorithm.

void vtkDEMReader::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)			`[virtual]`

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkImageAlgorithm.

virtual void vtkDEMReader::SetFileName ( const char * ) [virtual]

Specify file name of Digital Elevation Model (DEM) file

virtual char* vtkDEMReader::GetFileName ( ) [virtual]

Specify file name of Digital Elevation Model (DEM) file

virtual void vtkDEMReader::SetElevationReference ( int ) [virtual]
