High resolution, 11-channel multispectral scanner data were obtained for Winchmore Irrigation Research Station, Canterbury, New Zealand from an aeroplane flown at a height of 1.4 km. The data were analysed to see if a relationship existed between them and agricultural information, especially soil moisture levels. The study showed that multispectral data can be used to detect gross soil moisture variation. The thermal infrared band was particularly effective for detecting dry pasture. The study highlighted the need for data resolution to be appropriate to project objectives.
