Study the amount of waste collected pension in the city of Latakia and the need of the container and its spatial distribution using geographic information systems (GIS)

The disposal of solid waste is one of the most important contemporary environmental issues. Increasing population and what has been associated with the change in the patterns and lifestyles and increased consumption led to increasing the amount of produced waste and its quality, especially in cities; the estimated amount of solid waste produced daily in the city of Latakia was 840 tons. Thus, there is an urgent need to follow the techniques in the management of solid waste in all stages to maintain human health and protect the environment from pollution. This study as a whole aims to estimate the amount and characteristics of solid waste, the methods used to collect and analyze the spatial distribution of the current waste collection containers in areas of the city of Latakia, better planning commensurate with its population and the amount of waste produced using GIS technology. To accomplish this, we have a comprehensive field survey to collect the waste containers in the study area where they were monitoring their locations and identifying characteristics; we relied on statistical analytical approach in the recruitment of data that have been obtained, and used the map to the city of Latakia Tags. And, through the program (ARC GIS 9.3) the data has been entered and processed, linked and analyzed using analysis tools attached to the program, exit maps and various forms that serve the study. The study concludes that the current number of containers is not enough when discharged per day, and that the spatial distribution is not commensurate with the amount of waste produced in areas of the city .

Choosing the optimal paths to collect solid waste from containers distributed in Lattakia city areas using geographic information systems (GIS)

With the increasing population, the rising standards of living, industrial progress and rapid technological advancement, solid waste has varied and increased in amount as a result of various human activities. Thus, waste disposal has become one of the main problems facing cities and human populations because of the dangers posed by this waste to the environment and natural resources and health. Therefore, the development of an integrated management system for solid waste has become one of the most important elements of urban development strategies. Traditional management of municipal solid waste disposal, which includes collection, transfer and backfilling or burning operations, has evolved the concept of disposal of solid waste during the previous decades and begun waste management programs that focus on the use of computer programs such as geographic information systems, which help environmental planning for cities, and selection of the most optimal and economical solutions and. This study includes the use of geographic information systems software technology in the planning and selection of the optimal paths to collect and relay solid waste containers in the city of Latakia. In fact, selecting these routes undergoes the equations of length and time as to choose the shortest path, taking into account traffic regulations and diesctions in the streets. As for time, it takes the shortest path in terms of speeds specified for each road.

Integration of Remote Sensing and Geographic Information System GIS

Remote sensing technique is considered as one of the main sciences that grew very fast last years. Satellite images are important and advanced source to get data about any region on the earth. Using satellite images, integrated with geographic information system (GIS) for mapping are considered as one of the modern applications that expanded widely now a days. This paper aims at integrating the techniques of remote sensing and geographic information systems (GIS) for performing topographic study of landsat7 satellite image taken of a part of northern part of Lattakia. The two software, Erdas Imagine and ArcGIS are used to perform topographic analysis depending on digital processing for the image, then analyzing its terrain. Depending on digital terrain model (DTM), 3D slope image is derived. Land use map is written for the study area. Then, some spatial analysis are performed to find the best positions to construct different projects that have economic benefits. finally, analyses and results are discussed.

Evaluation of active tectonics in the northern part of coastal area in Syria using geomorphic indices and drainage analysis derived from a digital elevation model (DEM)

The research aims to evaluate active tectonics using DEM derived drainage network and geomorphic indices: streamlength gradient (SL), hypsometric integral (HI), basin shape index (Bs), mountain front sinuosity (Smf), and fractal dimension (FD).

Automation of cadastral plan by GIS

The programming interface presented in this research makes it possible to manipulate them easily and flexibly by all specialist users, as well as the possibility of managing, displaying, searching, amending and saving these plans through the approved programming interface which was applied to more than one real estate area. It is considered the foundation in the future comprehensive automation process of the Real Estate Department. In this research, the same real estate plotting approved by the General Real Estate Department was adopted ( real estate areas names and numbers) when manipulating them, using the ARC GIS 9 program.
