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.

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.

void vtkDEMReader::PrintSelf ( ostream &  os,

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

Specify the elevation origin to use.

By default, the elevation origin is equal to ElevationBounds[0]. A more convenient origin is to use sea level (i.e., a value of 0.0).

virtual int vtkDEMReader::GetElevationReference ( )
virtual

Specify the elevation origin to use.

By default, the elevation origin is equal to ElevationBounds[0]. A more convenient origin is to use sea level (i.e., a value of 0.0).

void vtkDEMReader::SetElevationReferenceToSeaLevel ( )
inline

Specify the elevation origin to use.

By default, the elevation origin is equal to ElevationBounds[0]. A more convenient origin is to use sea level (i.e., a value of 0.0).

Definition at line 67 of file vtkDEMReader.h.

void vtkDEMReader::SetElevationReferenceToElevationBounds ( )
inline

Specify the elevation origin to use.

By default, the elevation origin is equal to ElevationBounds[0]. A more convenient origin is to use sea level (i.e., a value of 0.0).

Definition at line 69 of file vtkDEMReader.h.

const char* vtkDEMReader::GetElevationReferenceAsString ( void  )

Specify the elevation origin to use.

By default, the elevation origin is equal to ElevationBounds[0]. A more convenient origin is to use sea level (i.e., a value of 0.0).

virtual char* vtkDEMReader::GetMapLabel ( )
virtual

An ASCII description of the map.

virtual int vtkDEMReader::GetDEMLevel ( )
virtual

Code 1=DEM-1, 2=DEM_2, ...

virtual int vtkDEMReader::GetElevationPattern ( )
virtual

Code 1=regular, 2=random, reserved for future use.

virtual int vtkDEMReader::GetGroundSystem ( )
virtual

Ground planimetric reference system.

virtual int vtkDEMReader::GetGroundZone ( )
virtual

Zone in ground planimetric reference system.

virtual float* vtkDEMReader::GetProjectionParameters ( )
virtual

Map Projection parameters.

All are zero.

virtual void vtkDEMReader::GetProjectionParameters ( float  data[15])
virtual

Map Projection parameters.

All are zero.

virtual int vtkDEMReader::GetPlaneUnitOfMeasure ( )
virtual

Defining unit of measure for ground planimetric coordinates throughout the file.

0 = radians, 1 = feet, 2 = meters, 3 = arc-seconds.

virtual int vtkDEMReader::GetElevationUnitOfMeasure ( )
virtual

Defining unit of measure for elevation coordinates throughout the file.

1 = feet, 2 = meters

virtual int vtkDEMReader::GetPolygonSize ( )
virtual

Number of sides in the polygon which defines the coverage of the DEM file.

Set to 4.

virtual float* vtkDEMReader::GetElevationBounds ( )
virtual

Minimum and maximum elevation for the DEM.

The units in the file are in ElevationUnitOfMeasure. This class converts them to meters.

virtual void vtkDEMReader::GetElevationBounds ( float  data[2])
virtual

Minimum and maximum elevation for the DEM.

The units in the file are in ElevationUnitOfMeasure. This class converts them to meters.

virtual float vtkDEMReader::GetLocalRotation ( )
virtual

Counterclockwise angle (in radians) from the primary axis of the planimetric reference to the primary axis of the DEM local reference system.

IGNORED BY THIS IMPLEMENTATION.

virtual int vtkDEMReader::GetAccuracyCode ( )
virtual

Accuracy code for elevations.

0=unknown accuracy

virtual float* vtkDEMReader::GetSpatialResolution ( )
virtual

DEM spatial resolution for x,y,z.

Values are expressed in units of resolution. Since elevations are read as integers, this permits fractional elevations.

virtual void vtkDEMReader::GetSpatialResolution ( float  data[3])
virtual

DEM spatial resolution for x,y,z.

Values are expressed in units of resolution. Since elevations are read as integers, this permits fractional elevations.

virtual int* vtkDEMReader::GetProfileDimension ( )
virtual

The number of rows and columns in the DEM.

virtual void vtkDEMReader::GetProfileDimension ( int  data[2])
virtual

The number of rows and columns in the DEM.

int vtkDEMReader::RequestInformation ( vtkInformation ,
vtkInformationVector **  ,
vtkInformationVector  
)
overridevirtual

Reads the DEM Type A record to compute the extent, origin and spacing of the image data.

The number of scalar components is set to 1 and the output scalar type is VTK_FLOAT.

Reimplemented from vtkImageAlgorithm.

int vtkDEMReader::ReadProfiles ( vtkImageData data)
protected
int vtkDEMReader::RequestData ( vtkInformation request,
vtkInformationVector **  inputVector,
vtkInformationVector outputVector 
)
overrideprotectedvirtual

This is called in response to a REQUEST_DATA request from the executive.

Subclasses should override either this method or the ExecuteDataWithInformation method in order to generate data for their outputs. For images, the output arrays will already be allocated, so all that is necessary is to fill in the voxel values.

Reimplemented from vtkImageAlgorithm.
