【Abstract】 A method of navigation measurement with GPS(Global Positioning System), echo sounder and HYPACK hydrographic surveying software is introduced, which has been used to the underwater topography surveying and sludge distribution information collection for the Jinji Lake. AutoCAD is also used to produce the color topographic map and sludge distribution map, and to calculate the graded area, graded volume and the volume of sludge in the Jinji Lake.更多还原
