## Wolfcamp Aquifer Data

### Description

Piezometric head measurements taken at the Wolfcamp Aquifer, Texas, USA. See Cressie (1993, p.212–214) for description of the scientific problem and the data. Original data were converted to SI units: coordinates are given in kilometers and pressure heads to meters.

### Usage

    data(wolfcamp)

### Format

An object of the `class` `"geodata"`, which is list with two components:

`coords`
  the coordinates of the data locations. The distance are given in kilometers.
`data`
  values of the piezometric head. The unit is heads to meters.
