Net Primary Productivity (California)

This data set was developed using MODIS MOD17 NPP and MCD12Q1 land cover type scenes for the entire state of California from 2002 to 2013. Images were re-sampled to 4km using bilinear methods of interpolation and re-projected to UTM WGS84 using the R library raster.本数据集基于2002年至2013年加利福尼亚州全域的中分辨率成像光谱仪（Moderate Resolution Imaging Spectroradiometer，MODIS）MOD17净初级生产力（Net Primary Productivity，NPP）与MCD12Q1土地覆盖类型影像构建。所有影像均采用双线性插值法重采样至4km分辨率，并通过R语言的raster库重投影至UTM WGS84坐标系。
