Abstract: 【Objective】Investigate the influence of station density on the accuracy of PRISM interpolation,in order to elucidatethe model’s scope of application.【Method】Based on the DEM of the northwest mountains of Beijing and rainfall data from the mountain automatic weather stations to calculate the result of interpolation.These results were then compared with the IDW,Kriging and Spline interpolation models using cross validation and test data validation.【Result】The precision of interpolation was reduced... More
