The Spatial Data Infrastructure (SDI) has emerged to facilitate the access, delivery and share of spatial information. It also results in greater effi ciency as limited awareness of existing datasets can lead organizations to duplicate data collection and register. SDI is an initiative that creates an environment in which spatial data stakeholders from different jurisdictions can co-operate and...
abstract this paper discusses several commonly used models for strategic marketing¹ including market environmental analysis methods (i.e. swot and pest analysis) and strategic marketing tools and techniques (i.e. boston matrix and shell directional policy matrix)and shows how these models may help a firm to achieve its strategic goals. at first, the main reason for doing this research is de...

A spatial data infrastructure (SDI) is a complex integrated network of spatial data producers, distributors and consumers that can be viewed as an extended geographic information enterprise. A way of gaining a better understanding of an SDI is to break it down into its constituent components so that individual SDI entities and their interactions can be analyzed. Prior SDI literature suggests an...
The system dynamics technique has been demonstrated to be a proper method by which to model and simulate the development of spatial data infrastructures (SDI). An SDI is a collaborative effort to manage and share spatial data at different political and administrative levels. It is comprised of various dynamically interacting quantitative and qualitative (linguistic) variables. To incorporate li...
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

It identifies the challenge...
This report addresses the question of how geographic and environmental information created and maintained by different organisations in Europe can be embedded in Spatial Data Infrastructures (SDIs) and reused in various applications by different people. The main challenge related to this task is to deal with the heterogeneity of data managed by others. The core concept of SDIs is interoperabili...
