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. IsTypeOfV.IsTypeOf(string) -> int C++: static vtkTypeBool IsTypeOf(const char *type) 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. IsAV.IsA(string) -> int C++: vtkTypeBool IsA(const char *type) override; 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. SafeDownCastV.SafeDownCast(vtkObjectBase) -> vtkDEMReader C++: static vtkDEMReader *SafeDownCast(vtkObjectBase *o) NewInstanceV.NewInstance() -> vtkDEMReader C++: vtkDEMReader *NewInstance() SetFileNameV.SetFileName(string) C++: virtual void SetFileName(const char *_arg) Specify file name of Digital Elevation Model (DEM) file GetFileNameV.GetFileName() -> string C++: virtual char *GetFileName() Specify file name of Digital Elevation Model (DEM) file SetElevationReferenceV.SetElevationReference(int) C++: virtual void SetElevationReference(int _arg) 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). GetElevationReferenceMinValueV.GetElevationReferenceMinValue() -> int C++: virtual int GetElevationReferenceMinValue() 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). GetElevationReferenceMaxValueV.GetElevationReferenceMaxValue() -> int C++: virtual int GetElevationReferenceMaxValue() 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). GetElevationReferenceV.GetElevationReference() -> int C++: virtual int GetElevationReference() 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). SetElevationReferenceToSeaLevelV.SetElevationReferenceToSeaLevel() C++: void SetElevationReferenceToSeaLevel() 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). SetElevationReferenceToElevationBoundsV.SetElevationReferenceToElevationBounds() C++: void SetElevationReferenceToElevationBounds() 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). GetElevationReferenceAsStringV.GetElevationReferenceAsString() -> string C++: const char *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). GetMapLabelV.GetMapLabel() -> string C++: virtual char *GetMapLabel() An ASCII description of the map GetDEMLevelV.GetDEMLevel() -> int C++: virtual int GetDEMLevel() Code 1=DEM-1, 2=DEM_2, ... GetElevationPatternV.GetElevationPattern() -> int C++: virtual int GetElevationPattern() Code 1=regular, 2=random, reserved for future use GetGroundSystemV.GetGroundSystem() -> int C++: virtual int GetGroundSystem() Ground planimetric reference system GetGroundZoneV.GetGroundZone() -> int C++: virtual int GetGroundZone() Zone in ground planimetric reference system GetProjectionParametersV.GetProjectionParameters() -> (float, float, float, float, float, float, float, float, float, float, float, float, float, float, float) C++: float *GetProjectionParameters() Map Projection parameters. All are zero. GetPlaneUnitOfMeasureV.GetPlaneUnitOfMeasure() -> int C++: virtual int GetPlaneUnitOfMeasure() Defining unit of measure for ground planimetric coordinates throughout the file. 0 = radians, 1 = feet, 2 = meters, 3 = arc-seconds. GetElevationUnitOfMeasureV.GetElevationUnitOfMeasure() -> int C++: virtual int GetElevationUnitOfMeasure() Defining unit of measure for elevation coordinates throughout the file. 1 = feet, 2 = meters GetPolygonSizeV.GetPolygonSize() -> int C++: virtual int GetPolygonSize() Number of sides in the polygon which defines the coverage of the DEM file. Set to 4. GetElevationBoundsV.GetElevationBounds() -> (float, float) C++: float *GetElevationBounds() Minimum and maximum elevation for the DEM. The units in the file are in ElevationUnitOfMeasure. This class converts them to meters. GetLocalRotationV.GetLocalRotation() -> float C++: virtual float GetLocalRotation() 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. GetAccuracyCodeV.GetAccuracyCode() -> int C++: virtual int GetAccuracyCode() Accuracy code for elevations. 0=unknown accuracy GetSpatialResolutionV.GetSpatialResolution() -> (float, float, float) C++: float *GetSpatialResolution() DEM spatial resolution for x,y,z. Values are expressed in units of resolution. Since elevations are read as integers, this permits fractional elevations. GetProfileDimensionV.GetProfileDimension() -> (int, int) C++: int *GetProfileDimension() The number of rows and columns in the DEM. vtkImageAlgorithmvtkAlgorithmvtkObjectvtkObjectBase!
