Extract By Mask for many data - using script of other method

SergeRafanoharana — Thu, 12 Jan 2012 02:14:14 GMT

Dear All,

I have a raster data containing the temperature, a very large area, and I have a shapefile containing my study area. Then I use the Extract by Mask in the Spatial Analyst Toolbox to crop my data. It is good but the thing is that I have monthly data for many years so I have to do it one by one. Is there another way or using script to do that for my data?

I tried the Map Algebra -> Multi Output Map Algebra but couldn't get it.

ExtractByMask tmean1 SHP_adm0 F:\DATA\test1
ExtractByMask tmean2 SHP_adm0 F:\DATA\test2
ExtractByMask tmean3 SHP_adm0 F:\DATA\test3
...

Thanks...

You can run a batch Extract by Mask process (Right click tool > Batch...). With the batch you can input all of your input rasters and then input your feature mask. Right click the cell of the mask and choose Fill. This will populate the same value into the other cells.
