How are functions applied to a raster image?
Raster functions can be applied to rasters in Desktop using the Image Analysis window. This window allows the user to apply different kinds of processing to one or more rasters. The Functions tab in the Mosaic Dataset Properties page is used to apply processing on top of a mosaic dataset. 1.
What kind of data is stored in raster format?
Data stored in a raster format represents real-world phenomena: Thematic data (also known as discrete) represents features such as land-use or soils data. Continuous data represents phenomena such as temperature, elevation, or spectral data such as satellite images and aerial photographs.
Why are raster images blurry and imprecise?
However, because raster images are pixel-based, they suffer a malady called image degradation. Just like photographic images that get blurry and imprecise when blown up, a raster image gets jagged and rough. Why? Ultimately, when you look close enough, you can begin to see the individual pixels that comprise the image.
Where can I find the raster function editor?
A raster function has parameters that can be edited by the user to control the processing it performs. These parameters can be edited using the Raster Function Editor page, which can be found at various places in ArcGIS Desktop.
Where can I find raster function templates in ArcGIS Pro?
Raster function templates can be used and distributed in several ways: Raster layers—Processing templates can be applied to layers in a project in the same way as an out-of-the box function. Processing templates are located in the Raster Functionspane on the Customand Projecttabs.
How to apply raster functions to a mosaic dataset?
Mosaic datasets—Functions can be applied to the entire mosaic dataset. To apply a raster function to a mosaic dataset, right-click the mosaic dataset in the Catalogpane and click Edit Mosaic Dataset Functions.
