Earth Resources Laboratory Applications Software (ELAS)
Abstract
Implementation of the Earth Resources Laboratory applications software (ELAS) system is described. A Data General Eclipse model S/230 minicomputer is employed for image processing of LANDSAT data. A 16 bit word is used, and the smaller addressability necessitates reducing some of the array sizes. All INTEGER*4 variables were changed to REAL. Interfacing the ELAS software to Data General's FORTRAN callable runtime routines required rewriting the input/output routines and the subroutines that bring in the various overlays. Overlay relinking is required when a change is made in resident routines. The ELAS system and its user documentation is evaluated.
