Abstract
Proceeding from a geographic database project (GIS), this research consists in composing a hypertext, that is to say : a network made of nodes and links for organizing information without a pre-established structure (web structure). The main hypertext nodes explicitly linked are human, scientific, computer and geographical activities. The geographical knowledge engineering proposed is based on our own reasoning, geographer's reasoning, and user's cognition in order to set in motion a humanistic geomatic.
