The "horizondata" web service provides meta data about a horizon dataset.

A typical URL is: http://myserver.mycompany.com:8080/INTGeoServer/json/horizondata?filePath=niobara.ixta

The following parameters are available:

filePath: the relative path of the specified dataset. This is a required parameter. If a path encoded is used, this path is encoded.

Here is an example response. This response has been formatted to improve readability

The name entry represents the name of the horizon dataset. This name is typically the file name without the extension.

The horizons node describes the collection of horizons that the file contains. Typically, there is only one, but some formats like the .xhz format may contain several.

The values sections is a collection of all fields of this horizon. For each field in the values section:

• • identifier is the unique id of a field

  • name is the name of a field

  • minimum is the minimum value of a field

  • maximum is the maximum value of a field

  • step is the step value of a field

  • isKey indicates whether a field is a key, meaning you can search points by this field (there is no search service at this time)

  • formatType: specifies the integer representation of a data type

  • description: specifies the description of a field

• timeFieldIdentifier is the identifier of the time (or depth) field
