Raster datasets are commonly used for representing and managing imagery, digital elevation models, and numerous other phenomena. Often rasters are used as a way to represent point, line, and polygon features.

May 4, 2026 - Continuous images can be displayed as data layers along with other geographic data on a map but are often used as the source data for image analysis. Thematic and digital pictures are often used as attributes in tables. They can be displayed with geographic data and are used to convey additional information about map features. Image and raster data is useful for a wide range of applications.

Once connected to ArcGIS Server, image services are shown with this icon: and are added to the map as a single layer. Click the Add Data button on the Standard toolbar. Click the Look in drop-down arrow and navigate to the folder, database, or server connection that contains your raster data.

Raster datasets are commonly used for representing and managing imagery, digital elevation models, and numerous other phenomena. Often rasters are used as a way to represent point, line, and polygon features.

A raster dataset can be created in any type of geodatabase or on its own on disk, such as a TIFF file. You can create a raster dataset using the context menu in ArcCatalog or using the Create Raster Dataset tool.

Image and raster data is usually stored in its original form. Rarely will you edit individual pixel values, like you might edit a feature in a vector dataset. You often process this data to create new forms that can be processed on the fly or saved as another version. These datasets, and collections of them, are often very large, so having good management capabilities is critical and ArcGIS ...

Many raster file formats are supported by ArcGIS. ... Spatial Analyst performs operations on square cells only. The size of each cell, known as its resolution, must therefore be the same in the x and y dimensions. Spatial Analyst operations are based on square raster cells (cell width = height). If you have input raster data in formats that support cells that are not square, before the operation is performed, the raster will first be converted to square cells.

There is extensive information on raster data available in the Rasters and images section of the Data Management > Managing geographic data documentation.

A raster dataset is any valid image or raster format organized into one or more bands. Each band consists of an array of pixels, and each pixel has a value. An image or raster dataset has at least one band. ArcGIS Pro supports more than 70 file formats for raster datasets, including TIFF, JPEG ...

Most imagery and raster data (such as an orthophoto or DEM) is provided as a raster dataset. The term, raster dataset, refers to any raster data model that is stored on disk or in a geodatabase. It's the most basic raster data storage model in which the others are built upon—both mosaic dataset ...

A raster dataset is any valid raster format organized into one or more bands. Each band consists of an array of pixels (cells), and each pixel has a value. A raster dataset has at least one band.

Number of bands—This is the number of spatially coincident layers in the raster. Rasters have at least one and may have hundreds. Data type—The data type, also known as pixel type, pertains to the type of values stored in the raster, such as signed integer, unsigned integer, or floating point.

This information can be accessed from any of the dataset or layer property pages and is organized into two groups (on two tabs): General and Key Metadata. To view the raster dataset properties in ArcCatalog or the Catalog window, right-click the raster dataset and click Properties.

In ArcGIS, there are three ways to work with raster data: as a raster dataset, as a raster product, and as a raster type. A raster dataset defines how pixels are stored, such as the number of rows and columns, number of bands, actual pixel values, and other raster format-specific parameters.

You can save the output to BIL, BIP, BMP, BSQ, CRF, DAT, Esri Grid, GIF, IMG, JPEG, JPEG 2000, PNG, or TIFF format, or any geodatabase raster dataset.
