EDIGéO Reader Parameters

Indicates whether the EDIGéO reader will not process the data that is read from the dataset to create higher order topological features.

In a EDIGéO dataset, when data is read without any processing, feature primitives do not have any geometry. Instead, "links" must be read from the dataset to link the feature primitives to geographical primitives. Thus, when this box remains unchecked, a significant amount of processing is done to construct each feature. In this process, not all of the original information can be output by the reader.

If the box is checked, data will be output by the reader exactly how the data is represented in the file, and the parameters Read Quality Data, Add Quality References to Features, and CNIG Names will have an implied value of No (so these parameters will be greyed out).

If selected, feature type names will appear as Conseil National de l'information Géographique (CNIG) nomeclatures.

An EDIGéO object code classification system is comprised of one alphabetical character followed by four numerics, each element delimited by an underscore (for example, H_11_4_0). If CNIG names is chosen, the reader will use the corresponding CNIG nomeclature instead of the EDIGéO object code (for example, H_11_4_0 will become PARCELLE).

Indicates whether quality features are read by the reader. Quality features have no geometry, and their feature type name will be a three-letter code. These quality features carry information that is complementary to topological features.

Indicates whether a list attribute, which carries values that reference quality features, is added to topological features.

The structured list attribute, which holds references to quality features, is named qal{}.ref_id. The format for the elements in this list is identical to the format of the format attribute edigeo_code.

Indicates whether verbose warnings and errors are output to the log file. These messages are in French.

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.

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.

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.
