| XYEvent2FieldsProperties | Defines the fields needed for an xy event layer, requiring atleast X and Y fields. |
The IXYEvent2FieldsProperties interface has properties for specifying the x field name, the y field name and the z field name. The x and y field name properties are required and must always return valid fields names, while the z field name is optional. The number 2 appears in the interface name because two of the three fields are required.
This information is used when creating a new XY feature class and can be returned from an existing XY feature class.
The fields must have numeric data types. For example, if your coordinates are stored in degrees, minutes and seconds, you need to convert them to decimal degrees and store them in numeric fields. These numeric fields can then be used to create an XY feature class.
