The study of computing method for ground leveling up volume of earthwork based on spatial interpolation
The calculation of groud leveling up is a very huge work,and the computational accuracy is restricted because of the irregularity of ground.Using spatial interpolation and the accuracy of model checking up,we choose a planning area as test region.We choose IDW as the best interpolation method.Then we work out the cutfill elevation of evry grid,cutfill area and cutfill zero line for the whole region,and figure out total volume.
Specialists concerned with the evaluation of the total environment of tropical grazing lands accept the fact that their own detailed studies should be a part of or a sequel to an integrated survey, as defined by Christian & Stewart (1968) — a survey of the physical and biological features, climate, water, soil, vegetation, minerals, terrain and natural environment. (See also annual reports of C.S.I.R.O. Division of Land Research.) Only indirectly arc the most important natural resource factors considered, the human (rural) occupants of a country who are expected to follow up the recommendations arising from the survey, for the ultimate benefit of themselves and the urban populations who are dependent upon them.
