This paper describes the use of satellite image interpretation for analysis of small-scale on-farm ponds in northeast Thailand based on field knowledge of hydrology and water uses. For the purposes, high spatial resolution satellite data, QuickBird, was employed to carry out image interpretations. The results show that 1)the type of ponds can be categorized visually from the viewpoint of the locations, 2)catchment location to the pond can be estimated from the intake point of water and the layout of the ponds, and 3)these methods can contribute to the evaluation of accuracy of DDM(Digital drainage matrix)processed from DEM. Through a series of image interpretations, the effectiveness of high resolution satellite imagery for field sciences and investigations was confirmed.
