Geographic Information System ( GIS ) is a computer-based system designed to manage the data question, use, evaluation and infinite visible picture of spacial informations. Clapp et Al. ( 1997 ) described that geographic data systems ( GIS ) as a strong software to buy and pull strings huge sums of information on spacial relationships. Information depicted consists of in writing and attribute data ( Taher Buyong, 1990 ) . Development of computing machine engineering presents already solves many roles that are chiefly in process of hive awaying informations, analyse and present geographically data.

2.1.1 GIS Definition and Concept

Geographic Information System ( GIS ) was an information system designed that related with referenced informations both spacial or geographical co-ordinates ( Ruslan & A ; Noresah, 1998 ) . It in addition to is a system that’s environment friendly within the data direction subject that entails a mix of spacial and attributes informations saved in a particular person database. GIS can besides help in doing determinations based mostly on the results of the evaluation generated by the system. Harmonizing to Li et Al. ( 2003 ) in Heng et Al.

( 2005 ) , GIS can make the most of to manage each spacial and non-spatial informations on the identical time where its consequence will demo in its specific features in data course and integrating, informations question and analysis, and informations visible image.

However, Maguire ( 1991 ) stated that it was hard to specify GIS because there have been many ways to specify and kind the thing and succesful. Heng et Al. ( 2005 ) defined GIS is a system that combines spacial and non-spatial informations to assemble a thematic map which depicting a assortment of demographic data associating to inhabitants, lodging and financial activities so as assist to work out location jobs and present the implications in envisioned signifier.

Harmonizing to Clarke ( 1986 ) , GIS was computing machine assisted systems for the gaining control, storage, retrieval, evaluation and show of spacial informations. While, from Burrough ( 1986 ) definition, GIS was a powerful set of instruments to roll up, store, retrieve at will, altering or reworking and exposing spacial informations from the existent universe. Then, GIS was a database path system with a spacial point out where it can supply research staff with first-class management over spacial relationships as described by Clapp et Al. ( 1997 ) .

Based on the given definitions, it is clear that GIS is targeted on processing and analytical capablenesss in deliver forthing new utile information in understanding the relationship of infinite ( Ruslan & A ; Noresah, 1998 ) . By and enormous, GIS is a course aggregation of computing machine hardware, bundle, geographic informations and the establishments had been expeditiously designed to roll up, store, update, manipulate, analyze and expose all signifiers of data referred to geographical location ( Aronoff, 1989 ) . In order to perform effectivity and better stimulation, assorted GIS utility had been designed to run into and carry by way of usersaa‚¬a„? demands and limitless demands. Besides that, informations presented could be extra effectual, environment friendly and attractive with the conceptualisation of ocular and show.

2.1.2 GIS Components

Harmonizing to Abd. Majid et Al. ( 2000 ) , there are six chief constituents for Geographic Information System ( GIS ) as follows: –

I. ) Data

Data is the inputs enter into the system either spacial or non-spatial informations. Data entry proficient can be done via the keyboard, scanning, digitisation and movie taking. The quality of the information produced will be more precise, accurate and replace.

two. ) Software

Lumley ( 1984 ) stated that, bundle is a plan that permits computing machine to indicate or execute a particular endeavor via a set of directions that has enrolled as a computing machine plan. These instructions enable the operation or computation performed by the computing machine. Example of the working system package corresponding to Microsoft Windows 2007, database direction systems similar to Microsoft Access 2007 and ArcGIS as an illustration for package.

three. ) Hardware

Hardware is required in GIS for informations entry, informations processing, informations storing and exposing the knowledge info stored indoors.

four. ) Application

In common, GIS software could be categorized into three teams that are societal, financial and army. This survey is categorized underneath financial.

v. ) Peoples

Peoples are an indispensable constituent in using GIS. This is as a outcome of human as administrators and applied scientists to ensure that GIS is used in the activity.

six. ) Procedure

The processs utilized in GIS are informations entry, informations storage, informations processing, presentation, path and care system. These processs are done in making an effectual information system.

Therefore, these constituents might be coordinated so that enables the system to work swimmingly. These constituents will do the GIS a system which helps in bring forthing penalties faster and extra accurate if utilized in the existent property improvement.

2.2 GIS Application in Real Estate Development

Zhao & A ; Zhang ( 2009, pg1 ) indicated that, aa‚¬A“In recent old ages, related administrative Fieldss of existent estate have been developed into a batch of subdivision industries associated to existent estate as a end result of existent property creating quickly. Directly, it has been strengthened the trouble of the existent property Fieldss as a outcome of the associated administrative content and concern course of have been changed with it. Therefore, a engineering so called GIS was set up to help to run convenient and heighten the executive energy of existent property, and besides higher the on the job effectivity. The structure of GIS has realistic significance for normative pull offing existent property and advancing the development of existent estateaa‚¬A? .

Geographic Information System ( GIS ) engineering integrates frequent database operations corresponding to query and statistical analysis with the alone visual image and geographic analysis advantages supplied by maps. These talents distinguish GIS from different info methods and do it valuable to a broad scope of public and private corporations for explicating occasions, foretelling outcomes, and be aftering schemes ( www.gisdevelopment.internet ) . Real estate trade is buying more bold twenty-four hours by twenty-four hours because of the speedy growth today. Particularly in the existent estate development, it wants the superior engineering helps to do the best dedication so that may minimise or keep away from the hazard of failure for a undertaking growth may confronted by existent estate builders.

As we all know, GIS is a computing machine based mostly system which is used to digitally reproduce and analyze the traits current on the Earth surface and the events that take topographic point on it. In the visible radiation of the very fact, about 70 % of the knowledge has geographical mention as its denominator. It becomes crucial to underscore the significance of a system which can stand for the given informations geographically ( ) .

Harmonizing to Zheng & A ; Zhou ( 2001 ) , GIS is specifically designed to manage spacial informations and capableness to execute these tasks.GIS developed as a generic device with capablenesss to cowl with uncertainnesss the place it can be utilized to many Fieldss which involve optimum spacial willpower devising. G.i. can be utilized virtually to place to death solution for greatest attainable spacial determination devising within the existent property industry. In the interim, it is proven that existent estate builders want GIS as a database path tool to assist them in making the willpower devising. The structure of willpower doing assist system has many advantages because of it can be used to beef up and better existent property control and to advance the event of the market ( Yang & A ; Qiao,2009 ) .

2.2.1 GIS Application in Site Selection

GIS is a powerful computer-based software to include and analyse spacial informations from assorted beginnings. GIS permits geographically referenced data to be saved, edited, manipulated and analyzed to bring forth interpretative map and associated statistic related for determination devising. GIS can provide an effectual platform for custom-made spacial modeling ( Barnett and Okowura 1993 ; Conway and Lathrop 2005 ; Goodchild 2005 ; Li and others 2005 ; Longley and Batty 2003 ; Tu and others 2007 ; Sorrentino et al.,2008, pg four ) . Barnett & A ; Okoruwa ( 1993 ) indicated that there have been few surveies utilized GIS in be aftering land usage and presented how GIS might be applied in existent estate market evaluation. They demonstrated the application of GIS in market analysis where particularly in site selection and location analysis for residential growth every bit good as in highest and finest utilization analysis. In the discovering of site alternative, the siteaa‚¬a„?s specific bodily and geographic features must able to fulfill the practical aims of a peculiar land usage.

Heng et Al. ( 2005 ) defined that website selection was important portion when planning for a existent estate enterprise development the place it was the nucleus part of the preplanning stage so the undertaking life rhythm shall be Begins. Largely, developers need to prioritise or select sites for development is based on the figure of sites on manus which can be found for a enterprise improvement as a outcome of limited assets. Besides, they might look for and choose the best new site from attainable places for development.

Site alternative usually involves discovering a suited website for a debatable development. Therefore, a number of standards ought to be studied and researched to obtain the accurate consequences. Among the cardinal aspects to be studied in a selection operation via the sheathing method is the facet of land usage, incline, geology, handiness, installations, inhabitants denseness and others. All aspects of the informations are analyzed to find and place attainable nations and absent for a improvement.

2.2.2 GIS Application in Determine Property Selling Price

Harmonizing to Zhao & A ; Zhang ( 2009 ) , GIS can be used to tug off the essential information of existent estate and at the identical clip produced the statistical research where promoting belongings part can point out to it as a point out dedication when find the financial value for belongings and carry on to sell it.
