The function of the EROS processor is to allow a user to select a specific area from a full frame LANDSAT image which is written on tape in the EROS format. The area of interest is read from the EROS formatted tape and converted to the JSC Universal format and written onto another tape. This tape can then be read by the IMDACS processing system and normal analysis can be performed

2. DESCRIPTION
2.1 PURPOSE
The purpose of the EROS processor is to allow a user to select an area
from an EROS generated tape and reformat the data into the JSC Universal
Format. The data can then be displayed or loaded by the CCAD image
processing system. IMDACS.
2.2 USAGE
The EROS processor is set up to run as a batch job. The input will be Band
Interleaved, Geometrically Corrected MSS EROS data tapes. The user will
input his area of interest and the processor will output a Universal
tape file for this area.
