In recent years, GIS software has undergone great development in many levels, although the basics of GIS have remained constant for a long time. In order to meet the requirements put forward by the global GIS community, Esri™ had to start over with a
n entirely new methodology, laying a solid foundation that would allow performance and experience to guide, the release of ArcGIS Pro. Which is the latest example of this qualitative leap in keeping pace with the visual development of the GIS interface, and the development in methods of sharing and editing on the web. Therefore, the idea of this project came to shed light on this platform, which represents a qualitative leap in the field of GIS software.
The importance of this project comes from the fact that it provides an educational guide with practical applications of the latest GIS software (ArcGIS Pro), where the project objectives can be summarized as follows:
• Provide a step-by-step introductory guide on learning to use the latest ArcGIS™ software ‘ArcGIS Pro’ from Esri ®;
• Topographical and detailed survey of an area within Tishreen University.
• Conducting practical applications within the ArcGIS Pro platform for the study area, by producing a topographical map of the studied area and performing some topographical analyzes.
The project includes four main chapters, the first chapter explains the concepts of geographic information systems (GIS), while the second chapter explains an introductory and detailed guide to the (ArcGIS Pro) platform, and the third and fourth chapters provide a practical application (field and office) to produce a topographic map within the Tishreen University campus, using ArcGIS Pro platform, with a number of spatial analyzes performed.
This study deals with the determination of total mercury concentration in the water
taken from three sites on Al-Kabeer Al-Shemaly River ( near the industrial area and Al-
Damat Lake, and 16 Tishreen Lake), also the effect of some physio-chemical p
arameters
including: DO, pH, T °C. of water in the three sites was studied.
Results showed that the total mercury concentration was low in general, where the
medium concentration in the three studied sites was 0.29 ppb and it was less than the
permission level of total mercury in the surface water(> 10 ppb), the higher value of the
medium concentration of total mercury(0.35, 0.31, 0.21)ppb was recorded in the Industrial
Area, Damat Lake, then 16 Tishreen Lake, respectively. For the changes in the total
concentration of mercury in the three studied sites during seasons of a year, was higher in
Summer comparing with other seasons. The results showed positive correlation coefficient
between the total mercury concentration and temperature, pH value, but it was negative
with DO in Summer.
The possibility to develop a High-Performance Liquid
Chromatographic method was studied for simultaneous
determination of: Cu(II), Ni(II), Co(II), Hg(II) by using DTC as
reagent. The diethyldithiocorbamate Reagent was studied by
spectrophotometric Method, Unique Ionisation Constant was
determined and its value.
