The "gridsurfacedata" web service provides meta data about a grid surface dataset.

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

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 grid surface dataset. This name is typically the file name without the extension.

The gridsurfaces node describes the collection of grid surfaces that the file contains. Typically, there is only one, but future formats might have several

The rowcount is the number of rows

The columnCount is the number of columns

The originX is the X position of the grid's corner for the first row and the first column

The originY is the Y position of the grid's corner for the first row and the first column

The rotationAngle is the angle (in radians) of the grid, taken from the grid's first corner and relative to the X axis

The values sections is a collection of all fields of this grid surface. 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
