RADARSAT-2 Reader Parameters

Dataset Parameters

Feature Type Name

This parameter allows you to choose different naming schemes for a feature type, and the number of feature types generated for the reader.

The Feature Type Name changes, depending on the selection.

Value	Feature Type Name	Example
From Format Name	<reader_type_name>	FORMAT_NAME
From File Name	<filename>	file
From Subdataset Name	<subdataset_name>	subdataset
From File Name and Subdataset Name	<filename_subdataset_name>	file_subdataset

Note: Some formats have an option for Scientific Dataset Name in place of the Subdataset Name. Examples for these formats are shown in the following table:

Value	Feature Type Name	Example
From Format Name	<format_name>	HDF4_ASTER
From File Name	<filename>	CURRENT_DHW
From Scientific Dataset Name	<scientific_dataset_name>	[331X720]_ SURFACE_FLAG__8_BIT_UNSIGNED_ INTEGER
From File Name and Scientific Dataset Name	<filename_scientific_dataset_name>	CURRENT_DHW_ [331X720]_ SURFACE_FLAG__8_BIT_UNSIGNED_ INTEGER

Apply GCPs

By default, the GCP information is preserved as properties on the raster geometry.

If you select this checkbox, the GCP information, including a GCP projection, will be read from the file and applied to the raster data as an affine transformation.

GCP Interpolation Method

Choose from NearestNeighbor (default), Bilinear or Bicubic.

Schema Attributes

Additional Attributes to Expose

Use this parameter to expose Format Attributes in Workbench when you create a workspace:

In a dynamic scenario, it means these attributes can be passed to the output dataset at runtime.
In a non-dynamic scenario where you have multiple feature types, it is convenient to expose additional attributes using this one parameter. For example, if you have ten feature types and want to expose the same attribute in each one, it is easier to define it once than it is to set each feature type individually in the workspace.

Use Search Envelope

Using the minimum and maximum x and y parameters, define a bounding box that will be used to filter the input features. Only features that intersect with the bounding box are returned.

If all four coordinates of the search envelope are specified as 0, the search envelope will be disabled.

Clip to Search Envelope

Select this parameter to remove any portions of imported features being read that are outside the Search Envelope.

The illustration below shows the results of the Search Envelope when Clip to Search Envelope is set to No on the left side and Yes on the right side.

No: Any features that cross the search envelope boundary will be read, including the portion that lies outside of the boundary.
Yes: Any features that cross the search envelope boundary will be clipped at the boundary, and only the portion that lies inside the boundary will be read. The underlying function for the Clip to Search Envelope function is an intersection; however, when Clip to Search Envelope is set to Yes, a clipping operation is also performed in addition to the intersection.
