A Context-Aware Approach for the Spatial Data Infrastructure Portal ()
ABSTRACT
The infrastructure of most
of the practical and construction activity in communities is based on correct
understanding and proper use of spatial data in GIS1 and SDI2. Optimal and
efficient use of infrastructure systems of the spatial data by users, depends
on how to search and access of user to proper and desired data among informative
sources of various organizations. Search operation and access of users to
various information of multiple sources located on Spatial Data Infrastructure
Network is confusing and time-consuming due to diversity and relatively high
volume of spatial information. Because there are numerous classes and
subclasses of various complications on the pattern of SDI, unaware user to the
pattern may be confused in select displaying the proper spatial layer. In
optimum condition, the user should have access to the appropriate data type
based on his status and task and environmental conditions. Making intelligent
Graphical User Interface by inference based on task information user and his
expertise, the appropriate information and consistent with conditions will be achieved.
Selecting and displaying of spatial layers related to the
technical-organizational approach of system user provides him special
assistance both in terms of filtering the irrelevant data and speed of
operation in access optimal information than non-selective displaying state.
For this purpose, designing and employment context-aware techniques in
servicing user interface of system based on recognition of the technical
expertise of the user can be a good solution in data adaptive displaying and
context-aware servicing to users.
