Additional Military Layers (AML) Reader Parameters
Action to Take on Update Files
Choosing this option will cause the AML reader to apply all updates available for the datasets read. That is, if there are files ending in .011, .002, and so on, in the same folder with base datasets (ending in .000), these update files will be read and applied to the base feature set in accordance with AML update rules.
Choosing this option will cause the AML reader to ignore all updates.
Features
Allows primitives to be read as individual features, whereby each feature has some extra information that could be used in future for writing to a AML dataset.
Schema Attributes
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 from 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.
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.
Select this parameter to remove any portions of exported features outside the area of interest.
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 clip is also performed in addition to the intersection.
About Mapping File Directives
Most mapping file directives correspond directly to a Reader or Writer parameter. To see detailed technical information for any format parameters, open the corresponding Mapping File Directives book in the table of contents.
