Export Raster

The Export Raster tool can export a raster surface and its metadata to a number of different formats. The output can be either a raster surface or a raster image that records the georeferenced information within the file, depending on the format of the input. For example, if the input contains an image band and CSAR is selected for the output format, the resulting file will be a raster image. If the input had been an elevation band, the output would have been a raster surface.

The Export Raster process is also available through Process Designer and the CARIS Batch command line tool.

If using Process Designer, it is possible to apply clipping and tiling as a precursor step in the export process.

Option	Description
Source	The name and location of the input file. The Source is defined by the dataset that was selected at the time the command was initiated. This field cannot be changed.
Format	The output format for the exported files. 1. Select an option from the drop-down list. If the BAG format is selected, the source dataset must have an elevation band.
Options	The options for the selected output format. The available options will differ based on the selection in the Format drop-down list. If you hover the mouse cursor over the name of an option, a brief description of the option is displayed in a tooltip. If the BAG format is selected, options are also provided for the BAG Metadata.
Status Indicators	Each option has a status indicator box beside the field. If the field has not been populated, or is populated with a default value, the box is coloured white. When a value is entered or a default value is changed, the status indicator box changes to grey to indicate it is no longer in the default state. If an option is mandatory, the status indicator box is coloured red. Fields can be returned to their default state by clicking the status indicator box and selecting “Reset”.
Output filename	The name and location for the resulting files. 1. Click the browse button (...) and specify a name and location.

The USGS format supports only Geographic and UTM coordinate systems and a limited number of horizontal datums (NAD27, NAD83, WGS72, and WGS84). If the selected surface references an unsupported coordinate system or datum, the export will fail. UTM data must also be in the northern hemisphere to be valid for the USGS ASCII Grid format.

The export is started. The Output window will report start and end times for each format exported. Additional information about the export process may also be displayed in the Output window.
