Understanding Raster Data Processing

What is raster data processing primarily used for?

• To create vector data

• To extract meaningful information from raster data

• To store data in a database

• To convert raster data to text

Which software uses raster functions to dynamically process imagery?

• QGIS

• ArcGIS

• AutoCAD

• Google Earth

What is the purpose of the Apparent Reflectance function in raster data processing?

• To change the colour of the raster

• To adjust the reflectance values based on scene illumination and sensor-gain settings

• To convert raster data to vector data

• To compress the raster file size

What is reclassification in the context of raster data processing?

• Changing the file format of a raster

• Reassigning values in a raster to new output values

• Merging multiple rasters into one

• Splitting a raster into smaller tiles

When should you use raster functions instead of geoprocessing tools?

• When you need a persisted dataset

• When persisted data is not needed

• When you want to change the file format

• When you need to export data to a database

What is a key advantage of using raster functions in ArcGIS?

• They permanently alter the source data

• They are lightweight operations that do not change the original source data

• They require extensive storage space

• They are only applicable to vector data

Where can you access raster functions in ArcGIS Pro?

• In the Layer Properties pane

• In the Raster Functions pane

• In the Geoprocessing pane

• In the Symbology pane

Which of the following is NOT a type of raster that raster functions can be applied to?

• Raster dataset layers

• Mosaic datasets

• Individual rasters within a mosaic dataset

• Vector shapefiles

What is the main difference between raster functions and geoprocessing tools in ArcGIS?

• Raster functions are slower than geoprocessing tools

• Geoprocessing tools create persisted data products, while raster functions do not

• Raster functions are only for 3D data

• Geoprocessing tools cannot be used for raster data

What is the benefit of using raster functions for temporary data processing?

• They require more processing time

• They save storage space and processing time

• They create permanent changes to the data

• They are only suitable for large datasets
