Error: Can not read scanlines from a tiled image

Error Message

When attempting to mosaic tiled TIFF images via the commandline or SDERASTER the process fails with the following message:

Creating raster layer: tif_mosaic.image

Image Dimension..............: 6114, 7557, 1
Pixel Type...................: uchar
image.tif: Can not read scanlines from a tiled image.
Error: Unable to read file image.tif
Error: SE_stream_execute (-1)
Error: Operation Failed


Tiled image TIFF files contain many tiles rather than a simple image. The sderaster tool expects a simple image and fails when it encounters the tiles.

Solution or Workaround

Use the TIFFCP tool to convert the tiled TIFF images to non-tiled TIFF images.
