The benefits of using GIS

The benefits of using GIS:

The benefits of using GIS for other systems such as management information systems of altered quality of the applications used and the nature of the geographic information stored in the database is different and the most important practical differences between these systems to management information systems are performing routine applications while implementing GIS applications is routine. It is intended routine applications, for example, to extract information about the rates of students at the university or staff salaries in a company provides students with signs and salaries of employees in the information base.
The application is routine, such as finding the number of employees in the company and who are away homes a distance of no more than 500 meters of a specific location or number of employees in the company who live in the area (a) as the system works to provide this and other information to choose the required distance space. The following is a simple explanation about the most important benefits in the use of geographic information systems:
First, save the information automatically
Of the most important benefits generally save the information automatically, coordinated and arranged and classified so as to facilitate access to the information required for quick and easy automated fashion. ()
Geographic information system can not analyze the information in the map, if these data were not in a digital computer can read body, which is flying the data. So use several ways to convert paper maps to digital maps. Punctuation is used (digitizing) to create a computer model of the author of the paper map-bound data, and accomplish this numbering process to follow by mouse or pen over a special surface to collect coordinates map landmarks. The survey is also used (scanning) also to get Mtsamth of paper map data. It can be used directly, when the geographic information system will be able to Almtsamth data analysis, or use it as a backdrop for the project if it depends on the data-bound. Almtsamth can also convert the data to a data-bound using a special data transfer between these bodies programs, and these programs are called as the acronym for the phrase R2V Raster to Vector.

Second, extract the information automatically
Save information digitally, any CNC especially if you use modern technology, which leads to reduced acreage and possibly cost, speed and accuracy of information retrieval.
Third, the speed of information processing
When the need for information or a map, access to it takes only seconds, the system automatically searches and display information or map required on the screen, as well as the possibility of system availability information in multiple formats, both in the case of paper or footage or graphic or even a digital to be used in the same system in the future or in another system, if there is the possibility of the conversion. And information processing depends on the efficiency of the hardware and software and high speed.

Fourth: the completion of the measurement processes and matching lengths and spaces
The benefits of GIS to obtain lengths and spaces of the lines and the shapes shown on the map automatically selecting the first and last point of the line or select a shape or circle to get the space and the length of the ocean. Among the benefits of these systems are also identical or map projection on each other for information and new maps derived from the basic maps.

The main interest in the form of flying data in their ability to represent the geographical features an accurate representation, and this makes them useful in spatial analysis tasks that require precise positioning, as in the engineering and surveying applications. Also, this type of data allows the definition of spatial relationships between features, such as the relationship between the two drugs neighborly relationship and communication Street another, any possibility of moving from the street to the other. This is known as topology (topology), which is very important in the network, such as finding the best routes between two locations in the complex network analysis methods.
Fifth: the linking and analysis of geographic and non-geographic information
Of the most important benefits of GIS to link graphical information geographical information for planning and decision-making, such as the population distribution in the city where the population requires knowledge of each group of pieces of land to the study, analysis and decision-making needed to develop and Development estimates.

Sixth: the speed of analysis and examination of models
You can use GIS not only to study and analyze the information available in the geographic information base, but also in the study and analysis of information resulting from planning and urban and environmental models and reproduction of geographic information and data.

Seventh: analysis of information at different times
Geographical analysis time associated where the planning and construction and environmental studies required to identify the change or impact of these plans on multiple periods. And using geographic information systems can recognize the changes that have taken place over time and can explain it to learn about the expansion of cities over the past fifty-year notes .. where speed and direction of expansion in this period of time.

Eighth: The display fee information
You can view and draw a geo graphical elements and using geographic information systems very quickly and choose the appropriate forms and colors and change so quickly is a good choice.

Geographic information systems and their relationship to scientific areas:
When talking about the various scientific fields, comes to mind the question: Is the GIS note? Or is it just a special type of technology? When taking the view that the GIS is simply a practical technique for computer, we may be far too much on the right, where there are more than a degree awarded to universities in the field of geographic information systems. If we examined the universities and institutes that teach GIS guide, we find that it contains about 445 department in the various disciplines that are taught in GIS.
Studies have shown that more than half of all disciplines that have applied scientific relationship with the GIS share (Geography) Valjgraveon considered one of the first who were interested granted full Applied take advantage of the efficiency of the computer information processing, as has already contributed since the beginning in the development of the use of computers in the graphic systems automated mapping and then GIS.
Now we have to explain the correlation between the GIS and the other scientific fields, where the interrelationship mean here is the effect of each party to the other and to highlight the features of this influence, both as a source for the provision of scientific material, or applied as a means or otherwise.

First: Geography:
GIS converge with geography to reach the peak and analytical functions to contribute to the development of assumptions or future predictions that can arise on the geographical phenomena.
It turns out that much of the technological areas in which GIS applied subject to geography and this is evidence of the close relationship between them and provide information fields that need to be applied where geographical information systems.

Second: science Alcartogeravia Cartography: is aware Alcartogeravia (cartography) of the most important branches of geography and who cares map, Alcartogeravia play an important role in the success of GIS, as shown famous ERIS Foundation in their own publications ARIC / INFO program that GIS depends on three scientific themes: Geography and Alcartogeravia, computer science, and this is what explains that Alcartogeravia important scientific element in this evolving field.
And what they offer can be listed Alcartogeravia to accomplish GIS in the points mechanism: 1. It is known that the spatial information is determined by the dots and lines and spaces, and the subject of each element including special such as fish, and the size and shape techniques, color and method of painting, and the rules of the spatial signature in line with the rest of the contents of the map, and these techniques are of interest Alcartogeravia which must familiarity in the implementation of the project in the GIS.
2. Offer Alcartogeravia an important aspect in the design of geographic databases.
3. is the subject of how to choose the scale of the map of the key issues of concern to the Alcartogeravia.
4. reflect the issue of the colors of the most important requirements of the display data in a GIS, Falcartogeravia allow appropriate rules for the choice of colors. ()

Third, remote sensing
Remote sensing is the study of phenomena from the air or satellite, which qualifies scientists to translate phenomena better way. This is a very useful tool to scan large areas relatively small cost. Sensor uses a remote for it in the study of polar deserts, forests and mountainous areas areas, The maps of small-scale and good accuracy can be produced at a lower cost basis of satellite pictures. In short, remote sensing suitable for the study of the difficult terrain, vast areas, and where the cost of expensive traditional work space. Provide satellites and remote sensing Bmaan inexhaustible source of information, including the study of the earth shape and topography and distributed land and sea on the surface, the study of plants, soil and mineral composition. The availability of so much time and cost required to complete the field survey is required. Information also helps
Captured Scientists regular intervals to discern the extent of the change in the ground conditions during the seasons, such as changes in seasonal soil moisture, and this information is very useful in areas with frequent changes in land cover her, such as agricultural land and the Jordan Valley and areas affected by tidal layout. ()
So is the remote sensing of the scientific areas that rely on geographic information systems, especially as an important source of modern and accurate globe for information.

Fourth: photogrammetry Photogrammetry
Pictorial space weather is the most important ground surveys to obtain detailed data accurate and that contributes to obtain information necessary for the production of topographic maps of the underlying data. It is known that geographic information systems rely on those maps (topographic) maps, essential.

Fifth: Area
Floor area contribute a large share in the field of field data collection necessary for GIS projects.

Sixth: statistics
Cares about statistics quantitative information, meet with GIS statistics are available, where those private systems to perform analytical processes on statistical data and functions.
The statistics are considered one of the important disciplines that contribute to the support of geographic information systems scientific article that rely on features of quantitative phenomena.

Seventh: Computer Science
There are four branches in the field of computer science that have a close relationship with geographic information systems, namely: a) the field of computerized design Computer Aided Design (CAD)
B) the field of automatic drawing Computer Graphics
C) the rules of information management systems Data **** Management System (DBMS)
D) the field of artificial intelligence Artificial Intelligence [IMG] file: /// G: / systems% 20 information% 20 geographical% 20 GIS% 20-% 20 Forum 20% easy 20% of the libraries of 20% and technology 20% of information T_ files / confused.gif [/ IMG]
