What are the critical steps in developing a successful environmental data system? This paper details the User Analysis phase of the REMSSBOT project. The phase consists of investigating user needs and requirements and creating functional specifications for each participating region. The study emphasizes the importance of the User Analysis phase for the REMSSBOT project. REMSSBOT intended to create a system to give users the ability to define a data search. This would allow the user to access structured data about the environment. The article outlines the procedures followed during the User Analysis phase. It describes the user needs and requirements for the REMSSBOT project, along with the partners involved and their current IT situations. These requirements are essential for building effective environmental **information systems**.
