Introduction
This document is written for users who use Format Conversion Tool for JERS-1.
JERS-1 dataset can be converted into GeoTIFF file format and KMZ file fomat by using this format
conversion tool.
JERS-1 dataset is made as CEOS file format. CEOS File format is restricted to use with GIS software.
Moreover there is few GIS software to use CEOS file format in the world. (Fig. 1)

Arc GISCEOSIt is hard to use CEOS format
directly because the general GIS
software can not handle CEOS.

By using this format conversion tool, JERS-1 dataset is able to convert into GeoTIFF file format andKMZ file format more easily.
So, JERS-1 data can be used with various softwares such as Arc GIS, QGIS, and Google Earth.
We hope to increase the ways to us JERS-1 dataset by using this tool. (Fig. 2)
