Most current geographic information systems assume and present the static world. But, new generations of GIS applications have much more demands in comparison to possibilities, which could provide traditional database management systems. Information that exists in the spatial database may be updated over time. Also, the very important demand is time capability to answer to state changing in dat...

Environmental pollution of urban areas is one of key factors that state authorities and local agencies have to consider in the decisionmaking process. Understanding temporal and spatial distribution of air quality at the landscape scale is essential in assessing the potential ecological conditions for ecological restoration and in making decisions for regional management. To find a compromise a...

BACKGROUND Reliable access to basic services can improve a community's resilience to HIV/AIDS. Accordingly, work is being done to upgrade the physical infrastructure in affected areas, often employing a strategy of decentralised service provision. Spatial characteristics are one of the major determinants in implementing services, even in the smaller municipal areas, and good quality spatial inf...

To date, much of the work that uses Geographical Information Systems (GIS) to study human geographies applies a social science paradigm to quantitative data. There is a growing recognition of the need, however, to test whether GIS can be used to map out the qualitative ‘data’ provided by the articulation of subjective spatial experiences. This paper expands the conceptual possibilities opened u...

The information needed for River Basin Management covers a wide range of hydrological and environmental data and methods. Since all measurement data are spatial and time related, spatial services fulfill the requirements in a decision making process best. In this work an open data structure for storing spatial temporal related data is proposed. Based on the data structure the modeling process c...

One of the challenges according to Dangermond (1999) and Tomlinson (2000) for GIS units in the 21st century is to be able to manage themselves successfully in order to deliver the right product at the right time to the right customer. Tomlinson (2000) also indicated that there will be several management tools available to assist GIS units to enable them to manage themselves successfully. This p...

Intelligent geographic information system (IGIS) is one of the promising topics in GIS field. It aims at making GIS tools more sensitive for large volumes of data stored inside GIS systems by integrating GIS with other computer sciences such as Expert system (ES) Data Warehouse (DW), Decision Support System (DSS), or Knowledge Discovery Database (KDD). One of the main branches of IGIS is the Ge...

Spatial Simulation in the context of Geographic Information Systems (GIS) is used primarily to assess the evolution of spatial variables over time. Since the 1990s two main techniques have been applied to perform this sort of spatial analysis: Cellular Automata [1] and Agent-based modelling [2]. The simulation models produced with these methods tend to be quite specific, only usable within the ...

Automated monitoring systems that can capture wetlands’ high spatial and temporal variability are essential for their management. SAR-based change detection approaches offer a great opportunity to enhance our understanding of complex and dynamic ecosystems. We test a recently-developed time series change detection approach (S1-omnibus) using Sentinel-1 imagery of two wetlands with different eco...

Geographic Information Systems (GIS) are computer-based tools used to collect, store, manipulate and display spatially-referenced information. They are used to support decision-making in a wide variety of contexts, including spatial planning and environmental management. Because the process of GIS production, from software development to visualization of GIS output, is characterized by politica...
