The infrastructure of mostof the practical and construction activity in communities is based on correctunderstanding and proper use of spatial data in GIS1 and SDI2. Optimal andefficient use of infrastructure systems of the spatial data by users, dependson how to search and access of user to proper and desired data among informativesources of various organizations. Search operation and access of users tovarious information of multiple sources located on Spatial Data InfrastructureNetwork is confusing and time-consuming due to diversity and relatively highvolume of spatial information. Because there are numerous classes andsubclasses of various complications on the pattern of SDI, unaware user to thepattern may be confused in select displaying the proper spatial layer. Inoptimum condition, the user should have access to the appropriate data typebased on his status and task and environmental conditions. Making intelligentGraphical User Interface by inference based on task information user and hisexpertise, the appropriate information and consistent with conditions will be achieved.Selecting and displaying of spatial layers related to thetechnical-organizational approach of system user provides him specialassistance both in terms of filtering the irrelevant data and speed ofoperation in access optimal information than non-selective displaying state.For this purpose, designing and employment context-aware techniques inservicing user interface of system based on recognition of the technicalexpertise of the user can be a good solution in data adaptive displaying andcontext-aware servicing to users.
