Would it not be possible to have a DTED reader connected straight to a MBTile writer?

This assumes that all the DTED files are the same LOD.

The MBTile writer will resample and retile and convert the format all automatically, based on the parameters.

thanks for the reply.

I tried loading multiple DTED 0 files to the DTED reader and connected it directly to a MBTile writer.

However, i keep getting the following error during the run:

MBTILES writer: Unsupported band interpretation 'INT16'. Please convert the interpretation to one of the following valid types: ALPHA8, BLUE8, GREEN8, RED8. This can be done with the RasterInterpretationCoercer and RasterBandInterpretationCoercer transformers

Thus i also tried the setup below, but also getting the same result as above:

any idea why?

Thanks in advance.

Managed to generate the MBTiles from DTED by setting both RasterInterpretationCoercer and RasterBandInterpretationCoercer to interpret Alpha16.

However i am still having an issue where by the each DTED file was converted to one MBTiles file.

I was hoping that the writer could just produce one single large MBTile file from all the DTED files input.

Do i need to add some Merger or Joiner transformer>?

One of the two interpretationCoercers should be sufficient.

What are the settings on your MBTiles writer?

Alternatively, you can use a RasterMosaicker to combine the DTED files into a single feature prior to writing.
