Creating flt (floating point grid) files for use in RAS Mapper

Creating flt (floating point grid) files for use in RAS Mapper

Creating flt (floating point grid) files for use in RAS Mapper

(OP)
Can anyone suggest a tool for converting DEMs to flt files? The flt file extension refers to a "floating point grid" file. RAS Mapper uses files of this type for terrain when mapping HEC RAS outputs.

I understand that this file type is associated with ESRI Arc GIS - is there any way for someone without access to Arc GIS to create these types of files?

Alternative, does anyone know the format of these files (I figure that if I know that, I may be able to write a script that converts DEMs to flts). Is anyone able to post an example of a flt file?

Thanks
