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.
|
This method is call by the superclass before an update. It sets the UpdateExtent to the WholeExtent. |
|
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 vtkSource. |
|
Accuracy code for elevations. 0=unknown accuracy |
|
Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkImageSource. |
|
Code 1=DEM-1, 2=DEM_2, ... |
|
Minimum and maximum elevation for the DEM. The units in the file are in ElevationUnitOfMeasure. This class converts them to meters. |
|
Code 1=regular, 2=random, reserved for future use |
|
Defining unit of measure for elevation coordinates throughout the file. 1 = feet, 2 = meters |
|
Ground planimetric reference system |
|
Zone in ground planimetric reference system |
|
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. |
|
An ASCII description of the map |
|
Defining unit of measure for ground planimetric coordinates throughout the file. 0 = radians, 1 = feet, 2 = meters, 3 = arc-seconds. |
|
Number of sides in the polygon which defines the coverage of the DEM file. Set to 4. |
|
The number of rows and columns in the DEM. |
|
Map Projection parameters. All are zero. |
|
DEM spatial resolution for x,y,z. Values are expressed in units of resolution. Since elevations are read as integers, this permits fractional elevations. |
|
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 vtkImageSource. |
|
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 vtkImageSource. |
|
Instantiate object with no start, end, or progress methods. Reimplemented from vtkImageSource. |
|
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 vtkSource. |
|
Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkImageSource. |
