System : B totality organized of components in interactions Physical plan (phenomena) Figure |. The three plans of a general system (adapted from Schwarz 1994) - A physical plan that includes the components, either, in the case of the territory (elements or facts); - A logical plan, non visible by our senses, that is the one with relations between components, that determines the working and the evolution of the system; - A holistic plan that is the one where the system is considered like a complex all, an indivisible unit without which components and relations would not produce the observed evolution. Say otherwise, the all, either in a way the identity of the system that emerges from interactions between components, gives a sense to these interactions. 3.2 Application Of The Systemic Approach To The Territory If we apply the systemic approach to the territory, we can distinguish the three plans of existence of a system plan : - The physical plan that contains systems (or subsystems) composing the territory, as well as the human's actions on this territory; - The logical plan or concepts that are composed of theories and models that we make from reality, as well as methodologies that we conceive to intervene on; - The holistic plan that represents the territory in its proper identity, its directionnalities, its values. 3.3 Application of the systemic approach to the GIS A GIS is a type of system constituted of computer components - material and software - of data, procedures and methods, of resources - financial human or scientific - that interact to do some tasks, to answer to requests and to produce information. We can also distinguish there above the three plans of existence of a system such as definied below : - the physical plan that contains data acquired from observations or measures, digital maps or documents, of pictures integration or orthophotoses, as well as the useful information notably to the development of projects, to the decision making or the simple information of the population; - the logical or conceptual plan that is composed of models shaping the different architectures of a GIS (organization, technique and information), which permit to elaborate processing methods (statistical or spatial analysis for 96 International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Vol XXXV, Part B-YF. Istanbul 2004 example) and of exchange principles (diffusion modes or rating for example); - the holistic plan that represents specific identity of the GIS and that expresses its privileged values (the exchange between partners for example), its finalities (to be a helpfull tool to the consultation, the management and the decision). The SRT can be defined as follows: The Systemic Representation of the Territory is defined as an interdisciplinary model of the territory (interdisciplinarity = multi - partners vision) based on the determination of phenomena and relations that composes it and that are applicable in the setting of the management, the planning and the scheduling of the territory. it takes into account their temporal evolution to avoid redundancies and incoherences. From this fact, it is considered as the most adequate to represent a territory in a GIS. The SRT constitutes a setting of reference for making an exchange network between partners possessing cartographic data (geographical information) and being called to work together in the setting of the planning and the management of the local territory. 3.4 Hierarchical organization of the SRT The Systemic Representation of the Territory recognizes six hierarchical levels of organization for its components (domain, sector, activity and clement, thema, class of entities, entity). This organization is not exhaustive. it covers aspects of the territory that we well know (according to investigations) or those for which we could take advantage of the specialist contribution (for what concerns natural habitations, activities, infrastructures, and the regional development). This organization has also a merely operational goal, which is to facilitate the access to informations, hence it plays the role of a of a navigation tool within the GIS. 3.5 Access Management according to the hierarchical organization of the SRT Some data are of confidential type and cannot be consulted by all the system users. These data remain under the exclusive responsibility of partners that provided them. The control of accesses first of all rests on the definition of groups users. These last are based on the administrative organization of partners. A specific group is formed of the set of users possessing the same privileges of consultation and modification of information of the system. If a group has access to a specific class (buildings for example), it also has access to the set of entities of this class (the set of buildings of the territory). However, it does not necessarly have access to the set of attributes describing this entity (Fig. 2). Domain Secfor Activity and element Thema Class [1] Figure 2.
