Today the desire to create smart and electronic companions in the daily life of humans has been fulfilled with the production of mobile processing equipment. On the other hand, the integration of existing capabilities of these equipment with the features of the spatial information systems, has become the basis for the emergence of a new technology called spatial information system. Simply put, displaying the spatial information can be considered as the most vital part of a mobile spatial information system. On the other hand, allocating a major part of the commercial market of mobile equipment to devices running with Android operating system encouraged the authors to explore different visual techniques in such equipment. The analysis can be considered as one of the most important studies required to develop a sample of a mobile spatial information system. But unfortunately, despite the great importance of this issue, no comprehensive and technical studies have yet been conducted to evaluate the performance of different methods of displaying spatial information in the context of this operating system. The methods used in this study include the use of Google Map API, ArcGIS Runtime SDK, OSMDroid, MapsFroge and Nutiteq libraries. To compare these methods and express the use cases of each of them, services were developed using each one of these methods and the Java programming language. Finally, after analyzing the results of various experimental experiments, the quality of performance, capabilities, strengths and weaknesses of each method were clearly expressed. In general, the results of this study can be considered as an appropriate starting point for selecting an appropriate library for displaying spatial information in any instance of a mobile spatial information system.

Social, cultural, and economic poverty is the most important factorbehind the emergence of suburbanization in cities.Although the suburbanites live in the realm of socioeconomic life of cities, they are not accepted as official citizens in the community. The main objective of this research is to provide strategies for empowerment of suburbanites inSonghor's town of shohada(of Kermanshah border province). Identifying the capabilities and limitations of suburbanite is very effective in achieving their empowerment strategies. The method of the research is a descriptive – analytical and survey method using Delphi method. The Method of data collecting is library method and interviewing experts and officials of Songor's municipality.QSPM and SWOT techniques have been used to analyze data. The results indicate that Suburban area in terms of the current situation is in a moderate position on the basis of the internal and external evaluation matrix,and in other words, the suburban region has not been able to exploit the strengths and has not taken advantage of the opportunities available and has been unable to escape the factors which cause its weakness and threat. Finally, after analyses done and providing a quantitative strategic planning and prioritization of the strategies,WO5's review strategyi.e holding of a justification workshop for urban managers to implement the empowerment and organization with a final score of 2.55,has become a top priority as the most important strategy. SO5's aggressive strategy i.e the establishment of a special committee for empowerment and organization holding special committee for empowerment and organizing is also in the second priority.

Nowadays Smart traffic sensor network is considered as one of the newest ways of data acquisition in traffic management which with the possibility of intelligent monitoring of urban roads, leads to road accident reduction. Despite the importance of installing and deployment of such equipment, the most important concern is to determine the optimal location for their installations. Therefore, what we are aiming at in this research, is to provide a suitable method to optimize the location of traffic sensors. The proposed method is a combination of FUZZY AHP and TOPSIS method. It should be noted that, in order to test the proposed method in this study, part of the urban road network in North America was selected as sample data. In the next step, according to traffic experts, the criteria for determining the optimal location were selected which included average annual traffic, crash severity, average slope and the distance of each connection in the urban network to places requiring traffic control. The FUZZY hierarchy method was used to determine the significance of input criteria. This method using FUZZY numbers in a pairwise comparison of criteria to calculate their weights, leads to an increase in the accuracy of computations. In the next stage, the weights calculated using TOPSIS method were used to rank the urban connections in the study area.
Eventually, after applying the above analysis using the score obtained from TOPSIS method, urban connections in the study area were classified in 3 different categories. Urban connections in the 1st category were selected as the ones with the highest priority for the installation of sensors. Therefore, these connections will be the top priority for the installation of traffic sensors.

Nowadays, remote sensing images are able to provide the latest information for studying land coverage and land uses, and the value and usability of produced maps depend on their accuracy. Hence, the purpose of this study was to evaluate the classification accuracy of LISS-III sensor's image of IRS-P6 satellite using the Google Earth's database in order to provide a map of land coverage and land uses. Therefore, the QUICKBIRD satellite imagery provided by Google Earth's software was used to determine both educational samples and to evaluate the classification. The studied area is Taleghan city in the Alborz province which is located in the watershed of Taleghan. In this research before determining the educational samples to verify the accuracy of the Google Earth's image, linear digital layers (roads and channels) with terrestrial coordinates were used which obtained an RMSE of 0.77.
In the next step, after determining the educational samples, the mentioned satellite image was classified into 5 categories of garden, agriculture. Pasture, lake and no coverage based on a supervised classification and with maximum probability algorithm using software ENVI 4/2 which obtained a classification KAPPA coefficient of 0.85 and an overall accuracy of 91/4.
The results of this study indicated that Google Earth's software images have a high spatial accuracy in order to evaluate the classification accuracy in some regions and also the use of ecological features such as the slope of the area, hydrologic network and… increase this accuracy. Finally, it is suggested that Google Earth's satellite imagery to be used to evaluate the accuracy of the satellite image classification and even visual interpretation of land coverage and land use.

Many developing countries are over-concentrated in a few urban areas. Such a situation leads to many problems. In this countries, the quality of people's is experiencing huge regional inequalities which are increasing rapidly in many cases. Environmental problems are one of the most fundamental issues in modern cities and are the result of conflict and confrontation with the natural environment. The result of this process will be the imbalance and incompatibility between man and nature and the collapse of the ecosystem relationship. The purpose of this research is to identify the variables of sustainable environmental development and assessment of sustainability in the cities of Khuzestan province. This is an applied and descriptive- analytical method research. The results of the research show that the cities of Izeh, Dezful, Andimeshk,Lali and MasjedSoleiman are at a higher level than other cities in terms of environmental development in khuzestan province. Also, the results of statistical tests indicate the superiority of the North of province to its south in terms of environmental development. However, there is no sensible difference between the east and west of the province despite the relative superiority of the east of the province to the west. The results of the Pearson correlation coefficient show that there is no meaningfulcorrelation between environmental development and population size of the cities and their Urbanization rate. This means that, there is no meaningful relationship between population size and urbanization rate with environmental development.

One of the major factors that affect Iran’s climate, is its location in different geographical latitudes and variety of uneven lands on one hand, and entering of diverse synoptic systems during the year on the other hand. One of the main parameters that determinesthe climate of each region is temperature, especially degree-day (DD).
DD is the difference of the threshold temperature relative to the average daily temperature, and the temperature thresholds are also selected according to the objectives of the research. In this study, the sum of the average numbers of the country's annual and seasonal heating and cooling degree-day was calculated through the temperature thresholds of 25.11 and 25.14 respectively.The daily temperature data was extracted from the Asfazary database. The databases include the daily average temperature in 41 years from 1961 to 2002 on the 15x15 km. cells throughout the country. Thus, the average daily temperature in Asfazary database is an array of 15992x7187 dimensions in which the rows represent the time (day) and the columns represent the location (cells). The results of the research indicate that the highest cooling degree-day (CDD) is from the 11 degrees temperature threshold in the summer and is about 600-750 related to the coasts of Oman sea and the plain of Khuzistan, and the lowest is from the 25 degrees temperature threshold for the entire Iran in winter corresponding to a zero CDD. Regarding the amount of heating required, the highest is from the temperature threshold of 14 in the winter which is related to the Northwestern area and the heights with a CDD of 600-750 and the lowest is in the summer related to the whole country with a temperature threshold of 14 degrees corresponding to a zero CDD.

Increasing the use of fishery resources and increasing global demand for food has created the need for a new look at the nature and the potential of the aquaculture sector andthis question is raised that how far aquaculture can increase protein production and human food security in the long run. The present study is an attempt to provide a part of the information requirements regarding the potential of aquaculture and the estimation of ecological and socioeconomic power of SARDASHT city in west Azerbaijan province for breeding cold water fish and mainly rainbow trout. This study has been conducted with the aim of locating and prioritizing SARDASHT’s underground water resources in West Azerbaijan province for the construction of rainbow trout breeding pools using geographic information system (GIS). For this purpose, after reviewing the sources and previous studies done in this field, effective measures in locating trout breeding pools were classified as: (1) ecologic- water (water’s rate of flow, type of water source, water temperature, PH), Shape of the land (slope, altitude), land use, distance from accidental areas (distance from flood areas, distance from earthquake areas); (2) economic - market proximity, profitability, and access to labor force; (3) social- employment, type of Exploitation ownership, population density; and (4) Infrastructure - proximity to the road, proximity to electricity, or proximity to telephone lines, and the like. Finally, it has been carried out using collected data and providing information layers in the GIS environment. The results revealed that out of a total of 208 sources of water being exploited, 141 sources of water had the ability for breeding trout.
