Benefits of Adoption of Standard I/F Various databases can easily connect and collaborate with each other Adoption of Standard I/F Users can enjoy active handling such as expansion/reduction, superimposing, thematic map generation with only browser instead of special applications for experts. Users can utilize satellite data in combination with other data Satellite data becomes more attractive and more utilized
