Inputs:
- Input raster dataset
- Output raster name and format
Output:
- A floating point raster.
Example:
|
Source Elevation raster |
 |
|
Result Aspect 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.
