The amount of memory that GeoExpress uses to perform operations depends on the following factors:
The image manipulation operations that you perform.
The operating system.
The image input format.
The number of bands in the output image.
The number of threads and concurrent jobs.
The strip height and block size.
Of these factors, you can control the strip height and the block size that GeoExpress uses.
Memory usage is constant over the length of the encode operation.
