This paper presents a post-classification approach that can achieve efficient results for change detection by using AdaBoost classifier. In the first step, a land cover of satellite image is classified in the independent fashion. For the stable classification of man-made structures, 3D features are employed. 3D co-occurrence feature is used with 2D co-occurrence feature and Harr-like feature. A...

Streamlined and efficient data maintenance processes are crucial to maintaining a GIS. Re-engineering of existing business processes in advance of data conversion is at the heart of ensuring that data is effectively maintained during and after conversion. Charlotte-Mecklenburg Utilities, (Utilities) has initiated a GIS Foundation project to convert its water and sewer system data into a GIS. Th...

The relationship between critical geography and geoinformatics has recently entered a new phase of cordiality and constructive discourse, exemplified by the NCGIA Initiative 19 [27], the Varenius project [21] and a variety of journal special issues on the topic of GIS and society (eg [28]). This new-found entente has opened the way to the re-evaluation of existing GIS-based research and to much...

Geographic Information Systems (GIS) services in academic libraries tend to differ, based on availability of GIS data, software, hardware, and staff expertise. GIS services at the University of Kansas are closely aligned with support for government information, data, maps, and statistics. Thus, our responses to users’ needs are often naturally collaborative, optimizing the expertise of multiple...

Geographic information systems (GIS) are becoming more usual due to the improved performance of computer systems. GIS applications are being developed using the three-tier software architecture traditionally used for generalpurpose information systems. Even though this architecture is suitable for GIS applications, the special nature and exclusive characteristics of geographic information pose ...

Green information system (GIS) plays an important role in the sustainable development of organizations, especially for those in emerging economy that face both economic and environmental pressures. To fulfill the purpose, employees need to work together on tasks using all kinds of GIS functions such as online collaboration and remote meeting. Researchers study GIS adoption at either the organiz...

The paper offers a detailed analysis of GIS integration as a curricula and technology in the Albanian market and institutional environment. The growing market needs for GIS utilities in Albania and the handicap, due to the lack of experts in geospatial technology constitutes a major concern. The research goal is to concentrate on the undisputed fact that the development of GIS curricula in the ...

GIS and Modeling Overview MICHAEL F. GOODCHILD NATIONAL CENTER FOR GEOGRAPHIC INFORMATION AND ANALYSIS UNIVERSITY OF CALIFORNIA SANTA BARBARA, CALIFORNIA Modeling can be defined in the context of geographic information systems (GIS) as occurring whenever operations of the GIS attempt to emulate processes in the real world, at one point in time or over an extended period. Models are useful and u...

Studies about geographical information systems (GIS) use contribute to geographic information science through critical evaluation of the concepts embedded in GIS tools. Social-behavioural studies about group use of GIS help us to understand the social implications of GIS because groups are fundamental units underlying intra-organizational, organization-wide, and inter-organizational activity in...
