Abstract
The main objective of this research was to determine Iran’s National Spatial Data Infrastructures (NSDI) readiness index, with the aim of identifying the basic restrictions that impede NSDI development. The framework of the research is constructed on the basis of survey and SDI readiness model. In this research, Iran’s NSDI based on this fuzzy-based model has been assessed using 16 decision-making criteria in the form of five organisational, human resources, data and information, technological and financial factors.The required data for the research were collected through the questionnaire and interview with the experienced experts from the government agencies, Universities, and private sector of the country who were familiar with the spatial data infrastructure. The results of the implementation of the model demonstrated that Iran’s NSDI readiness composite index was 0.44. In addition, the assessment of the factors of Iran’s NSDI readiness showed that all of them, with the exception of the technology factor, were less developed. Moreover, the status of 75% of decision-making criteria was not satisfactory. In this research, the state of investment of the government and the private sector, communication infrastructure, organizational and individual leadership, legal issues, politicians' perspective, metadata, culture and education regarding the spatial data infrastructure were recognized as the most important limiting measures in the establishment of the NSDI. In spite of numerous factors inhibiting the development of NSDI, the status of criteria for connecting to the Web, access to data and digital spatial data, human capital, and access to geospatial software were evaluated at an appropriate level of development. Also, according to the results of this research, it seems that in the development of the NSDI, non-technical issues (organizational, human resources, and financial factors) can play a role as a limiting factor than technical issues (technological factor). At the end of the paper, recommendations have been presented to resolve the country’s NSDI development constraints.

Regarding the level of technological development industrial and postindustrial countries have reached, it is hard to believe that once in this planet human beings could not even satisfy their basic needs, such as building a safe shelter. In the third millennium, access to information has resulted in the development of technology and has changed human life to a large degree. Nowadays, international power is a consequence of countries capabilities in exploiting their geographical environments; the way countries exploit their geopolitical situation creates an opportunity to appear powerfully in international realms. Superior technology is an important factor in securing countries against attacks or threatening other countries in preemptive wars. Superpowers such as USA possesses technologies and developed systems such as HARP. HARP is a research project apparently used for investigating and exploring ionosphere layer and underground mines (using ELF/ULF/VLF radio waves). But in reality, “a project with star war technology” has been launched to complete building a new weapon.
The present article takes advantage of a descriptive-analytic method and investigates HARP system using library and internet resources. This article aims to explore HARP system as a superior technology United States of America possesses and can use as a destructive or constructive weapon. Results indicate that the system has not been used for constructive purposes.

The advancement and development of computer hardware and software technologies has led the GIS to enter a new stage in its evolution. The Mobile Geographic Information System (Mobile GIS) is one of the dimensions of these advancements, which has entered various fields and has been used for various purposes due to its flexibility, its simplicity compared with traditional GIS systems, requirement of lower level of expertise and the fact of being less costly. Mobile GIS operates within a wider range of GIS technologies, wireless technologies and global positioning system technology. The system has many capabilities in various urban affairs including urban management, and can be utilized in areas such as emergency management, citizen participation, listing and maintenance of property and urban assets, security and public safety in the city and affairs related to customer service spatial issues. This article seeks to explore the applications of this system in various urban management issues while briefly introducing the Mobile GIS and its construction and architecture, as well as the importance of its application in various fields.
