This paper deals with the usability of vector geographic data structures. We define usability of a geographic representation as the ability to fit the user’s view, the user application and the user platform, plus the ability to be derived from a data producer dataset and to be maintained in the future if needed. Specifying the structure of a usable representation and deriving the corresponding data require specific tools and expertness. We propose to assist users in this process by means of a Web-based system able to assist users in specifying and performing a dataset restructuration process. The first step is to help users to set their requirements. To achieve this goal, we propose a graphical interface to specify differences between an existing data structure and a target data structure. The second step is to help users to commit these requirements into a transformation process applied to an existing dataset. We propose mechanisms to plan and execute this process and to check its result. The system relies on knowledge of existing data structures, platforms grammar rules and typical application schemas. The first part of this paper analyses the notion of a data structure and how to specify it. The second part describes our proposal.
