The increasing popularity of the Internet has led to the development of Web applications, known as Web GIS. A geographic information system (called GIS from now) is a software system that manages geo-referenced information. GIS systems are an automated system used for storing, analysing and manipulating geographical information. Geographical information represents objects and actions where geog...

This paper discusses applications of a revolutionary information technology, Geographic Information Systems (GIS), in the field of the history of cartography by examples, including assessing accuracy of early maps, establishing a database of places and historical administrative units in history, integrating early maps in GIS or digital images, and analyzing social, political, and economic infor...

Geographical Information Systems (GIS) have not yet been widely introduced to secondary school geography education in Finland. However, in the outline of the new national curriculum for upper secondary schools, GIS is incorporated into the elective, advanced geography course. The Finnish universities will therefore face new challenges in reconstructing their degree requirements for geography te...

Since 1996 Pierce County has utilized an ArcView application, called CountyView, as the county's enterprise GIS. After six years of use the application continues to draw more and more users, most of them grateful to be able to access the system from their desktop. This paper will attempt to describe what has made CountyView a successful enterprise GIS and categorize the elements needed in creat...

Public participation increasingly occurs in the context of modern GIS applications and goes much further than just crowd sourcing. Those web based applications enables the user to be actively involved in urban planning processes. Additionally, planners do profit from the participation of public. By the example of charging station for e-bikes, the participatory planning process is shown in this ...

Several surveys have shown that about 80% of data in local governments and utility companies are geographical and 1.5% to 2% of the annual budget of such sectors is spent on collecting geographic information. Therefore, such reliance on geographic information has necessitated the development of high quality Geographic Information Systems (GIS) with system qualities such as performance, availabi...

Geographical Information Systems (GIS) are increasingly used to appreciate how past people experienced their world. Two key approaches, visibility and cost surface studies, have been the dominant form of analysis to help archaeologists to reconstruct and visualize space, in other words to help archaeologists understand what it was like to be ‘there’ in the past. This paper seeks to question the...

This paper explores the relationships among the usability of a Web-based Public Participatory GIS (Web-PPGIS), the degree of pre-decisional engagement and decision outcomes in the context of a real-world participatory planning project. ArgooMap is used to support local residents in an online procedure for determining the “optimal” location of a new parkade in Canmore, Alberta. UsaProxy is emplo...
