Hi all,

I'm quite new with FME, so I hope you can help me. I would like to change the value of multiple rasters. I know you can do that for one raster, but I have a lot of rasters (>200). Is there a way to this?

I'm using FME desktop 2018.1.

Many thanks in advance.

Kees

    Depending on the size of the rasters, you can read them all in with one reader, and use a dynamic writer with the raster file name set to fme_basename.

     

    If your rasters are too large to process in one shot, you can set up a child workspace that does the processing (on a single raster), and then have a controller workspace that uses the pathnames reader to get the paths of the rasters, and send them to a workspaceRunner that calls the child workspace.
