Vector Product Format (VPF) Coverage Reader Parameters

Tile Parameters

ClosedTile IDs

Limits the geometric features that are produced. Only feature class features that exist in the specified tiles will be output. If no value is specified, all the tiles in the library will be used.

Syntax

<tileId0>, <tileId1>,...

To specify a range of tiles:

<tileId0>-<tileIdN>

This parameter is ignored if a tiled subset is specified for a nontiled library.

ClosedTile Extents

Tile extents will take a string formed by a comma-separated list of coordinates. The minimum x is followed by the minimum y and then the maximum x is followed by the maximum y value.

For example:

minx,miny,maxy,maxy

In this example, (minx,miny) represent the lower left corner of the bounding box and (maxx,maxy) represent the top right corner of the bounding box.

Schema Attributes

ClosedAdditional 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 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.
ClosedUse 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.

ClosedClip to Search Envelope

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.
