I am building a workbench that has a GeoTiff Reader, and uses the RasterPropertyExtractor and CoordinateSystemExtractor transformers to report on various qualities of the input image. The bounds, the cell sizes, etc.

I am hoping for a transformer that reports on the compression method of the input image. LZW or JPEG or something else?

Something similar to CoordinateSystemExtractor but instead a CompressionExtractor

Hi ​@nicholas ,

GeoTIFF reader reads the compression method as a format attribute called “geotiff_compression_method”, if the source GeoTIFF file was compressed.

 


Thankyou ​@takashi 

I took your advice.

I also added a NulAttributeMapper for those cases when the image is not compressed.
