Definition with GIS

Definition with GIS
GIS is the latest technique followed by using computers to save huge amounts from tabular data (which entails the tables and also called metadata) With large areas of the maps can not be saved in security on paper, and the data is saved with maps in a coherent and easy to Ali user display tabular data with maps and a variety of ways as well as a calculation processing to extract the results time and effort and benefit from few to take the appropriate decisionsGIS software features a user's ability to draw several maps in the form of layers and each layer a specific type layer from landmarks such as the scheme of the streets and the scheme of the buildings layer so that the user be able to hide any of them and show what he wants to get the best view.The most important benefits of GIS programs are as follows:1. Facilitate the mapping process no matter how large size and high accuracy so that ordinary people use in their work.2. Facilitate the process of saving data with huge maps inside the computer so that it can be accessed easily and make adjustments and perhaps this is the most important benefits of the system.3. Easy to show data on maps without having to manually Tsagatha where the required data is displayed and the form in which the user needs and easily high.4. Easy to back up data and maps and use when needed.5. Conduct searches within spreadsheets, for example, if we find a piece private Bmoasat land we can identify these specifications for the computer searches and display the results in very little time.6. Perform calculations on data tables For example, if we want to calculate the sum of the lengths of the pipes of a given diameter and made from one material, the computer will be the task of finding those pipelines as well as a total length to estimate the cost of replacement.7. Of the modern advantages of this system the possibility of making three-dimensional maps and benefit from them, especially in the case of mountain towns or cities that are located in flat areas.8. In the field of street networks can benefit from the software tools for the analysis of pathways and choose the most appropriate.9. In the field of water networks could identify places flaw soon to determine the homes from which the complaint interruption of water.10. In the field of sewage can easily locate blockages when this takes place.11. Connectivity with Server to track the movement of the body and directly.12. Among the new features are the ability to communication between several computers via local networks or the Internet to view and share data at high speed.13. The ability to use any coordinate system sometimes can convert maps from one system to another without getting any noticeable error.
