100 GIS practical application cases (51) - a method for calculating the hourly spatial average of NC files according to the specified range in ArcGIS

Preface

Calculation nc The average value of the specified range in the format file and export the results ,nc A file is a file that contains 432 Three dimensional data for months （ Here's the picture ）, Finally, I want to analyze the Ea Long term time variation characteristics of .

Ideas

Originally wanted to use python Handle , Because the specified range of files I need is tif Format ,python Albinism is usually done with shp Format file mask （tif I don't know the mask of the format , I didn't try ）, So it doesn't work python Handle , change to the use of sth. ArcGIS Software processing .

The work environment

ArcGIS10.2

01 take nc Files are converted into multiple files in batch according to time dimension tif file

（1） With the help of ArcGIS Medium ModelBuilder The module implements batch processing , open ModelBuilder, As shown in the red box below ：

（2） take Multidimension Tools In the toolbox Make NetCDF Raster Layer Drag in the newly opened ModelBuilder window , Here's the picture ：
