What raster data types does ArcGIS support?

Spatial Analyst operations are based on square raster cells (cell width = height). If you have input raster data in formats that support non-square cells, before the operation is performed, the raster will first be converted to square cells.

What is the resolution of a Spatial Analyst?

Also, in order to access many Spatial Analyst functions, it is necessary to add the Spatial Analyst toolbar. If the Spatial Analyst Extension is not loaded, it is still possible to add grid data sources to a data frame, but only as simple images.

Is the use of raster format in spatial analysis is useful?

The advantages of storing your data as a raster are as follows: A simple data structure—A matrix of cells with values representing a coordinate and sometimes linked to an attribute table. A powerful format for advanced spatial and statistical analysis.

What is raster based spatial analysis?
