GIS FOR REAL ESTATE – GIS for Business and Service Planning

“While the real-estate industry is most closely associated with location, it has been one of the slowest to catch on to the potential (Sherwood-Bryan 1993d). Nevertheless, it has started to implement a variety of applications (Castle 1993b). One of the most obvious, and least implemented, applications is supporting Multiple Listing Services (MLS) (Castle 1993c). An MLS is the tool that almost every residential realtor (estate agent) uses to analyse available properties. It is a computerized system that lists available properties and includes the characteristics of each property including size, type, number of bedrooms, listing price, etc. We are beginning to see inclusion of mapping capabilities into these systems.

GIS FOR TELECOMMUNICATIONS – GIS for Business and Service Planning

Telecommunications is currently one of the most dynamic industries in the United States and worldwide. Competition for the cellular telephone services market is strong in the US, and the company that can provide the best service has a significant advantage (Roan 1993). Current technology primarily relies on equipment within a “cell site” to control the communications interface between other cell sites and the traditional telephone system. Because the location of each very expensive cell site determines coverage, which in turn determines the level of service offered, optimal location of the cells is critical (Sherwood-Bryan 1993c).

GIS FOR RESTAURANTS – GIS for Business and Service Planning

Among fast-food chain restaurants such as McDonald’s and Burger King, the most visible and vocal users of GIS are at Arby’s. Among a variety of applications used at Arby’s is one that uses drive time to establish the likely trade area for an existing or potential store (Freeling 1993). In the fast-food business, customers are likely to be attracted more to the convenience of the product than to its gourmet appeal. It is, therefore, important to look at a trade area from the perspective of drive-time accessibility. Like many retailers, Arby’s personnel know how long someone will drive to access their product. In addition, they are familiar with the demographic characteristics of their typical customers. By analysing the demographics of a trade area established by using drive times, the likely sales performance for a store can be modelled. Arby’s is careful not to “cannibalize” an existing store when developing a new store. Cannibalizing means taking customers from one of their existing stores. Cannibalization should be avoided since a new store should increase overall business, not spread it around. By the same token, they are very eager to take away their competitors’ customers, and so they carefully analyse their competitors’ existing locations in comparison with their own.

GIS FOR RETAIL AND PRODUCT MIX – GIS for Business and Service Planning

Levi Strauss & Company (LS&Co) is a good example of a product retailer that has begun to use geographical technology to customize “product mix”, or the combination of products available in specific stores (Allen 1993). LS&Co is one of the world’s largest clothing manufacturers, and sells many product lines in addition to Levi’s jeans. Unfortunately, the company’s sales had been lagging significantly primarily as a result of mergers, acquisitions, price wars and significant retailers such as GAP chain creating their own product lines instead of selling LS&Co’s products.

GIS FOR INSURANCE – GIS for Business and Service Planning

It is highly likely that the insurance industry will soon face similar regulations to those already faced by the banking industry (Mertz 1993a). The reporting is likely to be at the zipcode (postcode) level. However, since this is in the future, this section on insurance will focus on current applications: risk assessment and avoidance. In the US, natural disaster after natural disaster has occurred over the last four years, bringing the total insurance industry’s bill to $34 billion (Mertz 1993b). Because of this, the industry has begun seriously to consider how it underwrites policies. The Oakland fire, Hurricane Andrew and the floods and other catastrophes of the summer of 1003 each pointed out the need for greater underwriting care. Insurance companies are beginning to realize that they must either refuse to insure properties that are at great risk from natural disasters, or justify larger premiums for doing so, or clearly identify precise areas in which property damage may be partially reimbursed from other sources. For example, the cross-hatched areas in the figure are wind-pools: insurers who write property-damage policies in these areas may be partially reimbursed by a state fund.

GIS for BANKING – GIS for Business and Service Planning

Perhaps the most important use of GIS in the banking industry is regulatory compliance (Tavakoli A. 1993). The Community Reinvestment Act (CRA) and the Home Mortage Disclosure Act (HMDA) are both laws which were passed in order to ensure that the banking industry does not practise “red-lining”. Red-lining is the illegal practice of geographically discriminating against groups (primarily minorities) by refusing to meet the credit needs of customers. For example, if a bank has a branch in an area and accepts deposits from customers within that area but refuses to lend money to those customers, that is considered red-lining. Red-lining reporting is done at the census tract level, making it an ideal application for business geographics. Banks use GIS to analyse whether they are guilty of red-lining, and if not, to help prove to regulators that they are not. Theoretically, if they do find that they are guilty of red-lining, they can use GIS to market to specific groups of customers in order to increase their lending activities within an area: I say “theoretically” because I have not heard of a bank that has admitted to using GIS this way since to do so would also be to red-line in a different way, which would also be against the law.

GEOGRAPHY IN BUSINESS? – GIS for Business and Service Planning


In the rush to create bigger and better technical solutions, many in the GIS industry tend to forget that the discipline known as “geography” is the basis of GIS. GIS provides nothing more than the opportunity to manipulate and analyse geographical phenomena using automated systems. In fact, Michael Goodchild, director of the US National Center for Geographic Information Analysis (NCGIA) quite “recently” suggested (Goodchild 1992) that the acronym GIS should be understood to stand for “geographic information science”. This new definition would place more emphasis on analysis of “geographic information” and less on “system”.
