Surfer can import and export ER Mapper grid format .ERS files.
The ER Mapper grid format consists of two files: a binary data file (no file suffix) and an ASCII header file .ERS.
The ER mapper grid file does not have a file extension. It should have the same format as a .BIL file, and it must have an associated ASCII header file with the same file name but with .ERS file extension. This header file contains data about the image such as the number of rows and columns in the image and latitude and longitude.
These files can be read directly by the ER Mapper software or by other packages such as ERDAS IMAGINE
Loading .ERS Files
ER Mapper .ERS files can be loaded to create a grid based map (i.e. Home | New Map | Contour) with the Open Grid dialog, or when using the functions in the Grid menu.
