For processing of remotely sensed data, the ERMAN-2 system which contains all steps for remote sensing is installed, modified, and tested. The Load application modules are modified to process the Landsat data which preprocessed in Japan. This modification makes all procedure for remote sensing to be performed by only ERMAN-2 system and also performed with PCIPS interactively. The system management programs are addeded for the system maintenance; the error debugging and the implementation of new algorithms. And the SEOUL image data is processed to get the efficient procedure. This thesis deals with all problems for the installation and maintenance of the ERMAN-2 system, and explains about the all applications and their results.
