GIS Shapefile Data: Identify

Concept Link IconSee Also

 

After using the Control page to read in shapes from a shapefile but before placing them on the diagram, identification options can be specified on the Identify page.

Identification String for Display Auxiliary Files

Shapefile shapes are created as background objects when added to a diagram. If using display auxiliary files to create or edit diagrams, objects must be uniquely identified. Because background objects typically do not link to an object in the power flow case, and therefore have no other unique means of identification, a unique ID string must be assigned to objects created via shapefiles. This unique identifier populates the Auxiliary ID field used in display auxiliary files and can be viewed from the Display Explorer.

Prefix 

Optionally, a prefix can be concatenated with the selected Attribute to further identify the shape.

Attribute

The drop-down box is populated with the fields that are available with the .dbf file. Choose a field whose value will be used to uniquely identify the shape. By default, the Record Number of the shape is used for identification if no other Attribute is selected.

Suffix

Optionally, a suffix can be concatenated with the selected Attribute to further identify the shape.

Linkage to Supplemental Data

Background objects created from shapefiles can be linked to Supplemental Data records for purposes of further identifying the objects. This is useful when applying filters, applying dynamic formatting, using Select By Criteria, or defining custom hints with display objects created from shapefiles.

Link Display Objects to Supplemental Data

Check this box to link the background objects created from shapefile shapes to Supplemental Data records.

Supplemental Classification

Select an existing Supplemental Classification from the drop-down box or click New to create a new Supplemental Classification.

Attribute for Supplemental Data Name

Select an Attribute from the drop-down box. The list of attributes is populated from the fields that are available in the .dbf file. For each unique Attribute value, a supplemental data record will be created with the chosen Supplemental Classification and with its Name set to the Attribute value.
