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 |

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
When selected, this parameter removes any portions of imported features being read that are outside the Search Envelope.
The example below illustrates the results of the Search Envelope when Clip to Search Envelope is not selected (set to No) and when it is selected (set to Yes).
- 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 selected, a clipping operation is also performed in addition to the intersection.
