Many Spatial Data Infrastructures (SDI) have been built in different countries with the main purpose of promoting social and economic growth, protecting the environment and to manage and reduce natural disasters. Although the ultimate goal is to create an effective and efficient data sharing and application environment, the major issues that these SDIs have overcome in order to be successful are different for each country, because they have been built trying to fulfill local specific requirements and deal with different difficulties. Interoperability and Standardization have been recognized as challenging issues for SDIs at the local level. However, when the sharing of data and geospatial services is between organizations from different countries, the problem of the interoperability and standardization become even bigger. The Infrastructure for Spatial Information in Europe (INSPIRE) is an example of a cross-countries sharing environment, where 27 countries have been making the transition from their local SDI perspective to a collaborative regional perspective. To facilitate a solid foundation for developing a SDI, we argued that the essential components of a SDI and analyses of their interactions and relationships must be carefully examined from a standardization perspective. As a SDI is built upon the collaboration of individual participants, this is not restricted to only technology consideration (e.g., what standards are used), but also consideration for data design, organization deployment, legal, and even cultural differences. We intend to identify the common and essential requirements for developing a SDI and propose our viewpoint about what obstacles should be removed to implement a healthy SDI. How the proposed mechanism can be used for different levels of SDI, e.g., NSDI and RSDI will also be discussed.
