String Attributes

String attributes are useful for incorporating category data into Imago imagery. Here we have an example of category data displayed on the light table alongside core images. In the Active Imagery panel, we can see that the data is organised as follows, from the attribute outward:

• The attribute Leda Detailed Litho displays lithology category data on the light table.
• An attribute definition called Leda Lithology contains the attribute Leda Detailed Litho.
• An imagery type called Supporting Data contains the Leda Lithology attribute definition.

The rest of this topic describes string attributes and how to make use of them in Imago. It is divided into:

• String Attributes in the Admin Portal
• Data Definitions Required
• Steps

String Attributes in the Admin Portal

In the Imago Admin Portal, the Supporting Data imagery type (A) contains the Leda Lithology attribute definition (B):

In turn, the Leda Lithology attribute definition (C) contains the Leda Detailed Litho attribute (D). Clicking on the attribute shows that it uses the permitted values from the Leda Detailed Litho legend definition (E):

Finally, the Leda Detailed Litho legend definition (F) contains the legend classes (G) that can be displayed on the light table:

Data Definitions Required

The data definitions required to incorporate category data in this manner are:

• A legend definition that will describe the categories possible
• An attribute definition that will contain a string-type attribute with the legend definition as its permitted values
• An imagery type that will contain the attribute definition

Steps

To set up a string attribute and use it in a dataset:

1. Create an attribute definition with your new string-type attribute.
2. Either select an existing legend definition from the Permitted values list or click the Create button to set up a new one.
3. Add your attribute definition to an imagery type.
4. Add the imagery type to a dataset.

String-type attribute data can be uploaded to Imago using Imago Connect. See Uploading Attribute Data to Imago.
