Challenges, management and innovations in geographic information systems (GIS) for transportation & institutional and technological challenges for the road centerline update problems
Abstract: The information and technology era is growing in a rapid pace; almost everyday we are introduced to a new technological breakthrough.
The society and living conditions of people is improving parallel to advancement of technology. GIS (Geographic Information System) is an example of technological advancement. In basic words, GIS combines layers of information together about one location and gives us better understanding of that place. We can say that GIS is taking geography to new dimensions. Geography with GIS is not anymore basic geography; we have added computer technology into basics of map making. This breakthrough technology is working in many ways and GIS-T (GIS Application in Transportation) is one of them. We are familiar with use of GIS-T from worldwide web, for example, MapPoint.net uses for map making. Beside it is web use GIS-T helps many governmental and non-governmental agencies to create solutions for everyday use. Some examples of GIS-T applications are: by counties that can map the county roads and borders or by emergency response teams who can navigate their vehicles. It is also used for bus routing and for land planning. While the stakes and its application are very abundant, problems with its uses are also unavoidable. In this paper we will look at application of GIS-T and the problems that are present with the GIS-T applications. When GIS-T application was created it was mostly based on street centerline theory and streets are identified as lines, which are passing through the middle of the streets. These lines carried to GIS-T applications with the help of CADD and DLG drawings. When we realize that we are surrounded with thousands of roads and highways, we also realize the greatness of information from these roads that should be carried to GIS-T. These information, either as drawings or electronic should be stored, processed and updated. After these updates GIST can be used most productive way, but with this much work and information, things do not always go as planned. There are common problems found with GIS-T use. The first problem is database updates and that means without update of road information's GIS-T is not useful. Second problem is limited data sharing, right now there are institutions working independently and processing their GIS-T information only for themselves. Guarding information is not useful for GIST application; it will be more useful if they share it. For example, between counties who have borders next to each other and who also have mutual goals. Another problem is the cost of information, which means institutions spend their own money, but problem with that some has more and some has limited budget, which affects the progress of GIS-T. Finally, we notice many technological management problems when we consider the goal of bringing GIS-T community and it is uses under one umbrella. It is a goal that has not succeeded yet and this failure is costing to every GIS and GIS-T user both as time and money. In this paper we will discuss these issues in more detail.
