Christopher, ER Mapper 6.2 cannot save out signed 16-bit TIFF files at present. Currently it is limited to saving imagery as either grayscale, palette-based (i.e. 256-color), or RGB TIFF files.
However, ER Mapper 6.3 will feature the ability to save images in unsigned or signed 16-bit TIFF format as well as the ability to save out "multilayer" algorithms (e.g. all seven bands from a TM scene) in TIFF format. ER Mapper 6.3 is currently in beta so if you have an up-to-date maintenance contract we can provide a pre-release version to help you out.

I need to export a signed 16-bit integer raster dataset to either a TIFF or other format ArcView can use. Every option I have tried - saving as GeoTIFF or as an Arc/Info BIL file changes the data to unsigned 8-bit. What I ultimately need is a GRID file that I can do some analysis in ArcView from this dataset. Can ER Mapper perform what I require?
