Raster dataset properties
A raster dataset's Properties dialog box lists the specific details associated with each raster. These properties are divided into five sections:
- Data Source
- Raster Information
- Spatial Reference
You can collapse and expand each of these sections on the Raster Dataset Properties dialog box as you explore this information; by default, all sections are expanded.
To view the raster dataset properties in ArcCatalog, right-click the raster dataset and click Properties. In ArcMap, right-click the raster dataset layer in the table of contents, click Properties, then click the Source tab. You can also obtain properties of a raster dataset using the Get Raster Properties tool.
The Data Source section describes the raster dataset's name, type, and location. If the raster dataset is on a database server, it has server information rather than path information. If the image is an image service,the Data Source section is titled Image Service and provides the appropriate information.
The Raster Information section lists the raster-specific properties, including the following:
- Number of columns and rows (of pixels)
- Number of bands
- Cell size (x,y)
- Uncompressed size
- Source type (continuous/discrete)
- Pixel type (unsigned/signed, integer/floating point)
- Pixel depth/Bit depth (1, 2, 4, 8, 16, 32, 64)
- NoData value
- Color map (present/absent)
- Pyramids (present/absent)
- Compression type
The Extent section describes the rectangle (boundary) containing all the raster dataset's data. The top, bottom, left, and right coordinates of the rectangle are listed in the same spatial reference units in which the raster is stored.
The raster dataset's coordinate system is described in the Spatial Reference section. All the spatial reference's parameters are listed; if a coordinate system has not been defined, this will be noted instead.
The Statistics section lists several of the raster dataset's statistics:
- Minimum value
- Maximum value
- Mean value
- Standard deviation
- Number of classes
