The characteristics of geographic data and the nature of geographic research require the participation of many agents. Data is generated by multiple sources (satellites, ground observation, weather stations, photography, etc.), accessed, processed and transformed by many users and available for use to an even larger population of users. Lack of coordination among all these different agents may render large amounts of work useless. Most existing GIS (Geographic Information Systems) do not provide any support for cooperative work, which adds to the problem. To overcome this serious limitation while still allowing users to take advantage of GIS technology, we propose GOOSE, a system implemented as a top layer for existing GIS. GOOSE provides the tools for constructing large geographic models in a cooperative environment with potentially many users and participants.

The Past

Developments in web mapping and web based geographic information systems (GIS) have evolved rapidly over the past two decades. What began as online map images available to a small group of geospatial experts and professionals has developed to a comprehensive and interactive web map based on integrated information from multiple sources and manipulated by masses of users globally. This paper introduces a framework that outlines the eras of web mapping and significant developments among those eras. From this framework, some of the influences and trends can be determined, particularly those in relation to the development of technologies and their relation to the growth in the number and diversity of users and applications that utilise web mapping and geospatial information online.

A new method for access management using traffic impact tools is described. The method targets impact assessment of developments combined with large activity centers. The magnitude of impact of large developments necessitates assessment of their regional and local effects on transportation networks. The method described combines regional and local traffic models and uses geographic information systems (GISs) as support tools. It was created as an access control method for computerized models and addresses supply-side transportation improvements (e.g., number of lanes, signalization, and parking controls) and their effect on traffic flow in an attempt to create better quantitative models for congestion management and access control by considering local and regional traffic impacts together. GIS technology enables users to create detailed highway networks for use in regional forecasting models and in smaller traffic simulation models. The data, models, and software used are outlined and an example of application is provided. The initial results show the efficacy of the concept and the resulting models. In the regional model, the new development generates not only new traffic volume on the network, but also route-choice changes influenced by the level of service on the specific corridors in the study area. Another component of the new model is a local model connected to a regional model through interface software. Using Traf-NETSIM, two scenarios were simulated to test the efficacy of this model system. Twenty-four independent simulation runs indicated that the access control scenario results in higher speed and less traffic delay on the primary arterial road.

Search And Retrieval

This article is an attempt to develop Geographic Information Systems (GIS) technology into an analytical tool for examining the relationships between the height of the bookshelves and the behavior of library readers in utilizing books within a library. The tool would contain a database to store book-use information and some GIS maps to represent bookshelves. Upon analyzing the data stored in the database, different frequencies of book use across bookshelf layers are displayed on the maps. The tool would provide a wonderful means of visualization through which analysts can quickly realize the spatial distribution of books used in a library. This article reveals that readers tend to pull books out of the bookshelf layers that are easily reachable by human eyes and hands, and thus opens some issues for librarians to reconsider the management of library collections.

Potential Applications

Geographic Information Systems (GIS) are becoming increasingly important to virtually all of the natural and social sciences. Applied economists will find that GIS can make valuable contributions to many of the problems with which they are concerned. Moreover, a great deal of the science behind GIS technology would benefit from the contributions of applied economists. This paper presents some initial suggestions for the ways in which GIS may be important to economics and the GIS related issues concerning which applied economists could provide useful insights.
