- Precision and complete geometric information of the under water surface, particularly in the sea area is very important to the planning purposes. Determination of the geometric of under water surface which is commonly used is sounding and remote sensing technique. For practical purposes, determination of shallow water surface could be done by means of photogrammetric technique. In this investigation photogrammetric technique was used on the simulation data. A number of control points on the water reservoir set in various of depth, then non metric camera was used to expose. The result of the exposure was processed analytically using Bundle Adjustment with self Calibration, and then correction to the water deflection was added. The result of the computation was tested statistically to know the validaty of the data and mathematical model. Furthermore to know the precision of the result, the out put was compared to the direct observation. The result of the investigation shows that in the convergent cases the accuracy less than 2 cm on the 100 cm depth. While for the vertical cases the precision was decrees liniary towards the depth of the water. Generally 2% accuracy of the height is suitable for mapping of the under water surface, specially in the mapping for shallow water surface
