This tutorial demonstrates accessing the export raster menu and reviews the different options available when exporting rasters.
Opening the Export Raster tool
To access the Export Raster tool, right-click your raster layer in the Contents panel and click-through Data > Export Raster.
clicking through Contents > Data > Export Raster to pull up the exporting tool
Alternatively, you can find the Export Raster tool by searching the toolboxes in the Geoprocessing pane.
Options in the Export Dialogue Box
Take a moment to look through the options available when exporting the raster dataset.
The options for exporting your raster dataset include selecting: the coordinate system, geographic transformation, clipping geography, cell size, raster size, pixel type, rendering settings, and output format.
Here’s a brief description of what you will find in the dialogue box:
Output Raster Dataset: The name and location on your drive where your exported raster dataset will be saved after exporting
Coordinate System: The CRS of the exported dataset. The default will be the CRS of the input raster.
Geographic Transformations: The transformation used when you switch between different coordinate systems, which is only applicable if the output CRS uses a different datum than the current raster dataset. (If a transformation is required, the software will recommend appropriate choices and pre-populate this option.)
Clipping Geometry: Specifies the extents of the bounding box used to clip the raster, if chosen. (This option can be used as a quick alternative to limiting geoprocessing extents.)
The Maintain Clipping Extent check box will force the output to maintain the extent specified by automatically adjusting the cell size and raster size if there is a conflict between your parameters.
Cell Size: Specify the cell size of the output raster dataset.The default value is automatically populated with the cell size of the source raster layer (information on pixel size can be found in the layer’s Properties > Source dialogue box).
Raster Size: The default value is automatically populated with the number of columns and rows required by the cell size parameter at the extents established for the output raster dataset.
These extents might be set by your geoprocessing extents, by the Clipping Geometry parameter (above), or will match the extents of the input raster.
Pixel Type: This determines the bit depth of the output raster dataset.
NoData value: Specifying the NoData value allows you to control the pixel depth and the value stores NoData. For example, you can choose here to replace “0” values with NoData in your exported raster dataset. (This is recommended if you are exporting to a file-based raster dataset and if a graphic clipping is chosen.)
Renderer Settings: Check the Use Renderer box if you want to export the raster dataset with the current renderer statistics option.
Output Format: If the output raster dataset (and location) parameter do not specify the output as a geodatabase raster, then you will need to specify the file format for the output raster. Similarly, you can (but are not required to) choose from different Compression Types and specify a Compression Quality value (ranging from 0 to 100).
