"A Geographic Information System (GIS) is a set of computerized tools (including both hardware and software) for collecting, storing, retrieving, transforming, and displaying spatial data."* GIS is essentially a marriage between computerized mapping and data base management systems. Anything that can appear on a map can be encoded into a computer and then compared to anything on any other map, using longitude-latitude coordinates.
Many people think of GIS as a presentation tool. A GIS does in fact create high quality maps that communicate considerable amounts of information in an efficient and attention-getting manner. ("A picture is worth a thousand words.") For example, when used to select the optimal site for a major retail facility in a certain submarket, in a few seconds a GIS can simultaneously display on the computer monitor:
All the census tracts in the submarket, with the color of each tract reflecting the number of households and median household income;
All the arterials, with the traffic volumes listed next to each street segment;
The sites of all potential competitors, shown as dots, with the size of each dot drawn proportional to the square footage or gross sales of that competitor; and
The locations of any toxic waste sites, flood zones, earthquake faults, or other environmental constraints.
The presentation benefits of a GIS notwithstanding, the technology's greatest power is in data assembly and analysis. Using the above example, a CRE might ask a GIS to draw maps identifying all places throughout the nation where the number of households and their incomes exceed a certain threshold, the number of competitors within a five minute driving time is below a certain number, and no environmental constraints exist within a one-mile ring. Similarly, when valuing a property a CRE might:
Download from a "comps service" all the recent transactions fulfilling certain criteria;
Have the GIS automatically locate the comps on a street map, listing next to each comp certain critical information (e.g., date and cap rate of the most recent sale);
By pointing to each comp with the computer's arrow keys or mouse, display a photograph or even video of the comp; and
Statistically correlate the property-specific information to all the demographic, traffic, competitor, and environmental information displayed previously.
Real estate professionals who are currently in the lead in exploring the endless possibilities of GIS are retailers, brokers, institutional investment managers, and property tax assessors. Among the professionals who certainly ought to be using the technology, but for various reasons have been slow to realize the potential, are real estate consultants, appraisers, corporate real estate executives, mortgage underwriters, asset and property managers.
The overall benefits of GIS include:
More credible decisions, based on incorporating more comprehensive data in the analysis, visualizing the information in two or even three dimensions, and rapidly testing numerous alternatives in ways not possible with other technologies;
Enhanced presentation of the analysis results ("How you say something can be as important as what you say'); and
As a result, an increased competitive position, greater revenues, higher profits.

Thanks Jafor for your good posting and try to encourage the student to read the GIS fundamental and actually try to know its application in the real world for better reflection. As a BRE student it is mandatory to know how to represent the real world value, coordination, latitude and longitude, land use and development planning and net working by using a powerful software ie ARC VIEW, ARC INFO and ARC GIS. It has a vest demonstration just read the following information's. However, just read the synopsis than you will know the sector diversification as a Real Estate student.
The term GIS may be a new tools for maximum students except those who are studying in Real Estate and Environmental Science and Disaster Management slightly known to this tools as well as its applications in the real world. Full application is computer base run by powerful software Arc Vie/Arc Info and Arc GIS. Accordingly, the purpose of these new terms is to provide an introduction to GIS technology and its application in different field and to help create a greater awareness of the privacy and access issues associated with this technology. The writing is to attempts, in a non-technical way, to define the technology and to identify common characteristics.
What is GIS? (Geographic Information System)
A GIS is a database management system that facilitates the storage, retrieval, manipulation and analysis of spatial and temporal data and its display in the form of maps, tables and figures. The information in a GIS describes entities that have a physical location and extent in some spatial region of interest, while queries involve identifying these entities based on their spatial and temporal attributes and relationships between entities. Geographic data refers to spatial data in terms of their position with respect to a known co-ordinate system, their attributes (which are unrelated to their position) and their spatial inter-relationships with one another.
Applications of GIS
In fact, GIS technology has developed so rapidly and extensively over the past two decades that some users now accept it as an essential tool for managing geographic information. Supporters believe this technology will fundamentally change the way information flows within and between organizations. The growing popularity of GIS applications is largely a response to the versatility of the technology. Outlined below is a description of some GIS applications.

For more details pls search Google (Just write GIS) and you will know more about the new technology. It is indeed and I would like to advice all of the student of BRE and ESDM in during study period try to know the practical technology. Our library has preserved some books you may visit our library to get pictorial and theoretical idea. Must visit ESRI site and to know the work activities how much powerful work are doing by using this technology.

THANKS SIR .....
-
Woaw !!!
I have learned many important things from here . For that reason I want to give thanks to my honorable teacher our Kafi sir and my friend Jafar .
But actually I am not clear about " k-12 education " .
What is this ?
can any one make it clear to me ?
-
really its a very important for our bachelor degree.
we hope that insallah our university arranged it.
we tring to learn more effective and easy way.
so thats why we have need this course in practical based.
thanks dear sir and my brother.
carry on

Dear All students, You will be happy to learn that department of BRE will arrange a training session on GIS and practically demo will be presented in the session hope you will learn and enjoy the modern technology.
Dear Jafar pls see the k-12 definition:
K-12, a term used in education and educational technology in the United States, Canada, and possibly other countries, is a short form for the publicly-supported school grades prior to college. These grades are kindergarten (K) and the 1st through the 12th grade (1-12). (If the term were used, "13th grade" would be the first year of college.)
Most communities in the United States and Canada (and wherever else the term is used) are just beginning to provide modern information technology at the K-12 levels.
