The maximum synthesis (MVC) can be done in band math in Envi, which is b1>b2, but cannot be batched. This article is now in bulk in ArcGIS using Python code, such as the following:The MODIS NDVI data used is the monthly data after splicing and projection in MRT, one months has two periods, the data format is. tif, the
Purpose : The maximum value of NDVI year or month is synthesized by using ArcGIS's own tool cell statistics to achieve multiple raster layer maximum values.Tools : arctoolbox>>spatial Analyst Tools>>local>>cell Statistics Issue : The NDVI raster image value is a float floating point between -1~1, directly using the Cell statistics evaluates to an int binary graph with a value of 0 or 1, not a floating-point
