The base and main essence of GIS in today's world is to provide reliable tools of decision-making based on geographic information. Given the wide-ranging applications of GIS, the new features considered for it, the accessibility, true dynamism, efficiency and practical advantages of GIS, it is expected that the GIS range of users find broader aspects. The base and essence of GIS in today's world is to provide reliable decision-making tools based on geographic information, and the presence of surveying engineers in the GIS environment requires careful planning, which is the basis for decisions and a guidance for future work. In an overview based on the diversity of working environment, GIS can be categorized as such: Collection of information; Combination of information; analysis of information; Presentation of information.

The Persian Gulf is a sea of warm water with an area of 240,000 square kilometers and a volume of 6,000 cubic meter, which is connected to the Oman Sea by the Strait of Hormuz. The length of the Iranian Persian Gulf shores from Bandar Abbas to the mouth of Shat-e-Arab is 1259 km and its length from the mouth of Arvand River in the northwest to the Strait of Hormuz in the southeast is at about 805 km. Its length from Shatt al-Arab to the shores of Abu Dhabi is 830 km and the length of the Arabian coast is about 1740 km. The average width of the Persian Gulf is 210 kilometers, with a minimum width of 185 kilometers and a maximum of 355 kilometers.

Although in the past centuries humans have used ground observations and direct presence on the site to study their environment, in the present century by conquering space by humans these studies are being carried out through space. Since humankind has been able to overcome the gravity of the earth and to separate from the surface of the earth, his imagination and observations concerning the information on the earth has changed. He studies and controls phenomena remotely from space, and from this point spatial remote sensing begins. Investigating phenomena while standing on the earth certainly has limitations. Spacecraft remote sensing features include comprehensive vision. Today in space remote sensing we inherit technology and transformations that thousands of people have made in their efforts to achieve this possibility, and even lost their lives in this way. The history of spatial remote sensing is full of successes and frustrations. In this article, we first look at the past developments of spatial remote sensing and then examine its outlook in the 1990s.

Water catchment areas: Western parts of Iran including mountainous regions of Lorestan are among water catchment areas. Their network of flowing waters are join the Persian Gulf watersheds, Hoor marshes located in the southwest of Iran or the interior regions of Iran (the central basin of Iran) due to the slopes and structure of the land. These focal points are divided into two permanent and seasonal groups, depending on geographical elevation and directions of terrain.
In permanent catchment areas where atmospheric precipitation is more in the form of snow, the snow storage remains almost until the later parts of the warm period because of high altitudes and great latitudes. These centers, the most important of which are Cazinistan, Oshtorankouh, Gerin and Mishparvar, are scattered mostly in the mountainous areas of the north and the east. Atmospheric rainfall in the form of rain as well as low altitude, lack of adequate snow reserves and openness of the valleys in some areas of Lorestan have caused the formation of temporary rivers; this openness in particular makes the waters caused by melting of snows to fall into adjacent plains and eventually into permanent rivers of the region; the southern heights, Sefidkouh and Shahtad Pahlou are examples of these water catchment areas. In addition to these cases, the water catchment areas adjacent to Lorestan, Kermanshah and Hamadan provinces have important roles in the reinforcement and feeding of the network of flowing waters of this province.

Carl Steinitz, in his speech at the EGIS 93, describes the methodology of a project for outlook planning.
In 1990, after nearly twenty-five years of utilizing GIS in many projects, I came to the conclusion that there is a common structure for the continuation of this work, and in the October 1990 wrote a brief article entitled "A Framework for Theory" in the Outlook Journal, and this theoretical framework has become the main pattern of teaching and research in my projects in the last three years. In this article, I will try to present a brief description of this framework and show how it is used in a project.
As a teacher, I have always believed that we should be able to benefit from a comprehensive, integrated and adaptable approach when dealing with theory and practice. I do not accept and indeed reject the "up-to-down" theory of the approach or model of outlook planning which has universal application. Instead, I believe that an appropriate strategy is, first and foremost, a” perception”. My research for the underlying framework in which I organize this process has shown that there is a great deal of structural (and perhaps necessary) similarity among some of the questions raised by outlook planners and other environmental design experts.
Professor Amos Rapoport (University of Wisconsin) has described a useful definition for theories, models and frameworks. He briefly states: “A theory explains, a model predicts and organizes a framework; a framework can be judged based on its rationality and merit, but it has no claims against other frameworks.

The Solar System is exposed to collision with rocks that have remained since the formation of the planets. Asteroids and meteorites are examples of this group of rocks. The first known asteroid was discovered by the Italian astronomer Giusepppe Piazzi on January 1, 1801, and was called “Ceres” after the goddess of plants in ancient Rome. This asteroid is located at an average distance from the Sun of less than 2.8 AU (Astronomical Unit) (2.8 times the distance of the Earth to the Sun) and it takes it 4.6 years to traverse its orbit around the sun. The largest asteroid has a diameter of about 1000 km. Its mass is supposed to be about 30% of the total mass of all asteroids. Three asteroids of Ceres, Vesta and Pallas have a diameter of 500 km, and it is estimated that there are at least 100,000 asteroids with a diameter of about one kilometer, but there are more than 200 asteroids whose diameter is about 1000 km. It was once thought that asteroids are the pieces produced by the “efforts” of a former planet. But if we bring all asteroids together in a single unit, this unit will equal about 5% of the mass of the Moon, and this amount of matter can only form a body with a width of 1500 kilometers. Most astronomers now believe that asteroids are objects that whose formation goes back to the time of formation of planets, namely 4,500 million years ago. These pieces could never come together to create a single planet.

In the course of the centuries and millennia of history, human has always sought to discover the mysteries of nature and unknown regions through scientific travels to different parts of the world, and today the scope of such scientific research has become so developed that human beings, through space travels, seek to discover the secrets of the universe and conquer the space, and, it is to say that on the way to this end, the thoughtful man has acted bravely and avoided no effort.

In this study the newly independent republics of Central Asia including Uzbekistan, Tajikistan, Turkmenistan, Kyrgyzstan and Kazakhstan have been examined in terms of population and human resource issues. The major ethnic-national groups of these republics include Uzbeks, Tajiks, Turkmens, Kyrgyz and Kazakhs, who follow the religion of Islam. Other population groups include the Russians, Ukrainians, Germans, Karakalpaks, Tatars, Uighurs, Dungans, Armenians, Jews, Koreans and ….
In order to examine the human resources of these countries in terms of their quantitative and qualitative aspects, certain population, social, cultural and economic issues have been studied and relationship with these newly independent states have been discussed. Separate survey of quantitative and qualitative demographic characteristics of each of these republics will be presented in near future.
