Although place-based investigations into human phenomena have been widely conducted in the social sciences over the last decades, this notion has only recently transgressed into Geographic Information Science (GIScience). Such a place-based GIS comprises research from computational place modeling on one end of the spectrum, to purely theoretical discussions on the other end. Central to all research that is concerned with place-based GIS is the notion of placing the individual at the center of the investigation, in order to assess human-environment relationships. This requires the formalization of place, which poses a number of challenges. The first challenge is unambiguously defining place, to subsequently be able to translate it into binary code, which computers and geographic information systems can handle. This formalization poses the next challenge, due to the inherent vagueness and subjectivity of human data. The last challenge is ensuring the transferability of results, requiring large samples of subjective data. In this paper, we re-examine the meaning of place in GIScience from a 2018 perspective, determine what is special about place, and how place is handled both in GIScience and in neighboring disciplines. We, therefore, adopt the view that space is a purely geographic notion, reflecting the dimensions of height, depth, and width in which all things occur and move, while place reflects the subjective human perception of segments of space based on context and experience. Our main research questions are whether place is or should be a significant (sub)topic in GIScience, whether it can be adequately addressed and handled with established GIScience methods, and, if not, which other disciplines must be considered to sufficiently account for place-based analyses. Our aim is to conflate findings from a vast and dynamic field in an attempt to position place-based GIS within the broader framework of GIScience.

Post Soviet Period

Since the 1990s with the increase in the role of migration in the formation of the population in the post-Soviet space in the Kaluga region, as in other regions of Russia, the tendencies of population reproduction and its regional features have changed somewhat. There are many ways to analyze demographic processes. The advantage of the cartographic method is in the visual display of the characteristics of the objects of the territory in terms of space and time. With the use of geoinformation technologies, geographic information systems (GIS), in particular, it is worth talking about the improvement of the cartographic method and the formation of the geoinformation method in geography, new or previous methods and methods of cartography have appeared or have been updated, the study of demographic processes for the user of geoinformation systems proceeds more efficiently and quickly. In research were used descriptive-analytical, comparative, cartographic, geoinformation, centrographic methods. GIS analysis was carried out on the basis of the free cross-platform geographic information system QGIS (Quantum GIS). A unified technique for GIS analysis of the region’s demographic processes is being developed on the basis of methods and techniques of geoinformation modeling and mapping. For visualization and subsequent creation of maps, a number of methods and methods are used, including: typological, method of cartographic anamorphic images, method of qualitative and quantitative background, methods of areas, cartodiagrams, ranges of values, method of movement of arrows, etc. For geomodeling of the population reproduction in the Kaluga region, we have chosen 1989–2020. as covering the main trends of population reproduction in the post-Soviet period. As a result, we examined the demographic processes of the Kaluga region, namely, the regional features of the process of population reproduction in the region in the post-Soviet period and the role of migration as a factor in the formation of the population at this stage, the change in the settlement system within the region. The geodatabase “Demographic indicators of population reproduction in the Kaluga region” created for the analysis of regional features of the transformation of population reproduction, formed on the basis of custom sets of layers of spatial and semantic data of the districts of the Kaluga region, and built cartographic models.

In this chapter, we present the Web-based carpooling system ORISS, which was initially developed by a student project group at University of Oldenburg. It is currently being deployed at Carl von Ossietzky University of Oldenburg with support of the DBU (Federal German Foundation for the Environment). We describe the role of carpools in traffic, particularly in commuter traffic, and show perspectives of an increased usage of carpools. A significant impact on the eco-balance of the university can be expected. We explain how Internet technologies and geographic information systems can be used for the arrangement of carpools, and show advantages over traditional methods of carpooling. The concrete architecture of ORISS and the algorithms used are outlined. We conclude the chapter by describing the circumstances of deployment and propose possible future extensions of the system.

State Programs

Geographic information systems (GISs) are becoming more widely used in transportation planning agencies, especially among metropolitan transportation organizations. The extension of GIS into transportation (GIS-T) is driven largely by the requirements of the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA), the Clean Air Act Amendments of 1990, and legislation by states that mandate the development of transportation programs to reduce traffic impacts. Traditionally, transportation modeling of traffic impacts, calculation of vehicle emissions, and consideration of wider transportation planning effects, including transit, have employed different modeling techniques, often in different agencies or in separate sections within an agency. The results from these modeling and planning exercises have more often than not been displayed on different map bases, using different graphic programs to represent the data. The requirements of federal and state programs are encouraging modelers and planners to consider more consistent methods of data integration and display, hence the growing interest in GIS-T. The role of GIS-T in regional transportation planning is evaluated, including data integration issues, the configuration of transportation networks for use with GIS, and the linkage of transportation models to GIS.

Abstract. This article primarily describes the nature of geoinformatics, including the role of each of its components as understood today, and illustrates how the change in demand and the progress in science and technology are the two driving forces for the development of this subject. The changes in popular needs are next analyzed in detail, focusing on four aspects: the user group, intended usage, medium, and service. Lastly, it points out that geoinformatics work should be conducted following the development of geographic information.

The study aimed at extracting the valley and streamsnetwork using GIS in Bethlehem governorate and assessing the risks of floods and the most flood prone areas in the governorate in order to forecast and reduce the disaster risk related to the flood. With a description of the role of GIS in the work of hydrological analysis in order to benefit from the flood waters by identifying the optimal areas for the collection of flood waters. It showed the extraction of the map of the water streamsnetwork and the identification of river basins using GIS , and the ability of geographic information systems to assess liquidity risks, as well as the production of accurate and illustrative maps showing hazard locations, was demonstrated. And reviewed the role of GIS in the industry of opportunity and reduce the risk of disaster Through the use of floods and identify the best areas proposed for the collection of rainwater and then work on storage. It recommends the establishment of a national information bank, which will be responsible for each part of the information, to create a spatial database system that contains comprehensive maps in all areas within common standards, which will assist in disaster management and support decision-making in times of crisis and disaster using GIS.
