Read more about Hillshade and its importance here.
Inputs:
- Input raster dataset
- Output raster name and format
- Light azimuth (0 to 360)
- Light altitude(0 to 90)
Output:
- A floating point raster.
Example:
|
Source elevation raster |
 |
|
Result Hillshade raster |
 |
|
Elevation raster (50% transparency) over the Hillshade raster |
 |
Notes:
- Initially the name of the output raster
defines the raster format
- no extension specified - ESRI binary GRID
- .img extension (for example raster1.img) - ERDAS IMAGINE image.
- .tif extension (for example raster1.tif - Tagged Image File Format (TIFF) image.
- The initial output raster format can be changed by selecting the desired output in the dialog.
- Currently only file based rasters are supported. Rasters cannot be stored in a GeoDatabase. After you get the desired result, you can export the raster to a GeoDatabase using the standard ArcGIS tools.
- The input raster must be in a projected coordinate system.
Command line syntax
ETS_GPRasterHillshade <Input Raster> <Out Raster> {Light Azimuth} {Light Altitude}
Parameters
| Expression | Explanation |
|---|---|
| <Input Raster> | A Raster dataset or Raster layer |
| <Out Raster> | A String - the full name of the output raster (A raster with the same full name should not exist). The output raster type depends on the extension of the output file(see Notes above) |
| {Light Azimuth} | A Double representing azimuth of the light source (0 to 360). 0 indicates North, 90 - East, 180 - South, 270 - West |
| {Light Altitude} | A Double representing the altitude of the light source in degrees (0 to 90) |
Scripting syntax
