Using the areal weighting interpolation and inverse distance weighted averaging, a spatial distribution model of GDP is established in this paper.
After obtaining the raw data, a simple method is used in the paper to process forest fire related data from 1999 to 2000, in which the data at arbitrary site is calculated by inverse distance weighted interpolation.
In this paper, we discuss a method based on inverse distance weighted ( IDW ) algorithm to construct seafloor digital terrain model ( DTM ) using multi-beam soundings, and the application of level of details ( LOD ) technology.
Based on the interpolation of known observation data, the spatially continuous distribution of raster data were obtained to realize data grid, spatial distribution maps of spare sunlight disasters in Jiangsu Province were gained by using the inverse distance weighted interpolation method.
According to the features of micro-geomorphology of seabed and pipeline, a method based on inverse distance weighted ( IDW ) algorithm to construct seafloor digital terrain model ( DTM ) using multi-beam soundings, which can improve the ability of multi-beam echo sounder on pipeline inspecting.
