На основе современных технологий разработана структурно-функциональная модель «Информационная система обеспечения градостроительной деятельности». Данная модель использована в качестве основы для создания моделирующей геоинформационной системы. При этом в виде отдельного структурного элемента в систему интегрирована информационная база данных о сейсмичности и сейсмических рисках, включающая в себя карты детального сейсмического районирования (ДСР) Республики Северная Осетия-Алания и карты сейсмического микрорайонирования территории населенных пунктов – административных центров Республики Северная Осетия-Алания. Рассмотрены методы оценки возможных социальных и экономических потерь от возможных землетрясений различной интенсивности и разработана методика оценки сейсмического риска. На их основе, предложен алгоритм «внедрения» (введения) методики оценки сейсмического риска в информационные системы обеспечения градостроительной деятельности. Использование разработанной методики оценки сейсмического риска территории позволяет непосредственно рассчитать рейтинг грунтов и сейсмический риск территории. На территории г. Владикавказа выделены участки с различными грунтовыми условиями. На основе имеющихся данных создан ГИС-проект «База данных геологической информации территории г. Владикавказа», включающий информацию о пробуренных на территории города скважинах и составе соответствующих грунтов. Данная база интегрирована во вновь разработанную систему, что позволяет использовать её в качестве одного из основных источников информации в задачах моделирования ожидаемых последствий опасных природно-техногенных процессов On the basis of modern technologies developed structural-functional model « Information system for urban planning». This model is used as a basis for creating a modeling geographic information system. At the same time, an information database on seismicity and seismic risks is integrated into the system as a separate structural element, includes maps of detailed seismic zoning (DSR) of the Republic of North Ossetia-Alania and maps of seismic micro – zoning of the territory of settlements-administrative centers of the Republic of North Ossetia-Alania. The methods of estimation of possible social and economic losses from possible earthquakes of different intensity are considered and the method of seismic risk assessment is developed. On their basis, the algorithm of "introduction" of a technique of an assessment of seismic risk in information systems of providing town-planning activity is offered. The use of the developed methodology for assessing the seismic risk of the territory allows you to directly calculate the soil rating and seismic risk of the territory. On the territory of Vladikavkaz allocated areas with different soil conditions. Based on available data created the GIS project "Database of geological information of the Vladikavkaz city territory ", which includes information about wells drilled on the city territory and the composition of the respective soils. This database is integrated into the newly developed system, which allows to use it as one of the main sources of information in the problems of modeling the expected consequences of dangerous natural and man-made processes.

Site selection is very important for any construction of structure and management. The appropriate site selection gives very good life and durability to the structure. Site selection is also improving quality of the structure and life of the structure. So, site selection is very important in of structures. In this, Geographic information system is a tool used for site selection of structure. Geographic information system is used to analyses and manipulate the spatially referenced data. It is also known as remotely sensed data or information. Geographic information system is giving a better output with in short period of time. So Geographic information system is most widely used now a days around the world. In recent developments attribute data are analysis by using Geographic information system. The selection of site depends on soil conditions, environmental conditions, weathering agencies etc. so proper planning and design of site selection is very important to make a structure in long life and increase the life span of the structure.

Operating Modes

Because vehicle activities and the emissions associated with them can be correlated with specific points in time and space, the modeling capabilities of a geographic information system (GIS) are well suited to the modeling of mobile-source emissions. A GIS-based modeling approach can provide emissions estimates for both on-network and off-network vehicle activities on a modal basis (as a function of various vehicle operating modes that significantly affect vehicle emission rates). An entire metropolitan region can be modeled on a zone, link, and point basis. Vehicle subfleet composition can be tracked or estimated and combined with estimates of vehicle activity and characteristic operating modes to provide emissions estimates in a spatial and temporal context. Emissions from various modal activities are aggregated into grid cells to be used as input to an airshed model. Identifying spatial and temporal distributions of these activities adds to a greater understanding of emissions impacts. A research prototype of this modeling concept was produced to illustrate its capabilities and identify difficulties that must be addressed in the development of a fully functional model. The GIS-based displays and hard-copy maps that present the spatial variability of emissions levels help improve the communication of research findings to decision makers and the public. The effort being undertaken at Georgia Institute of Technology in conjunction with the Environmental Protection Agency to develop a next-generation modal emissions model within a GIS framework is described.

Flood is one of the most frequent hydrometeorological disasters which leads in economic losses. The first step in flood disaster mitigation efforts is mapping vulnerable areas. Kencong District frequently affected by the annual flooding event. This study aims to assess flood hazard mapping by integrating the AHP method and Geographic Information System. This study used a descriptive quantitative approach through the correlation matrix of the AHP model for each physical environmental factor. These factors include slope, altitude, distance from the river, soil type, Topographic Wetness Index (TWI), and Curvature. Furthermore, with the Geographic Information System (GIS), the weighted overlay stage was carried out to obtain the results of flood-prone areas. Based on the AHP analysis, the most significant factors in determining flood-prone areas were the distance from rivers, slopes, and TWI. The results of flood-prone areas mapping were divided into five classes: from deficient 0.02%, low 4.26%, medium 37.11%, high 51.89%, and very high 6.72%. Validation of GIS mapping results with data in the field has an AUC value of 84%, which indicates that the prediction of the AHP-GIS model is perfect in flood-prone areas mapping in the Kencong District. The integration of AHP method and Geographic Information System in flood hazard assessment were able to produce a model to evaluate the spatial distribution of flood-prone areas.

Jember is one of the regencies in East Java having tsunami-prone areas. Regional Disaster Management Agency (BPBD) of Jember defined six sub-districts that are vulnerable to tsunami disasters comprised of Kencong, Puger, Gumukmas, Wuluhan, Ambulu, and Tempurejo. Settlements in coastal areas are at risk of being affected by the tsunami. The residential household close to the seashore is centrally located in Kencong, Gumukmas, Puger, and Ambulu sub-district. The high density of buildings can cause economic losses and fatalities in the surrounding area when a tsunami disaster strikes. This research aims to identify and measure tsunami risk levels in all coastal villages of the Jember Regency. The research method used a quantitative approach through scoring and weighting technique, also a disaster risk matrix. Spatial analysis conduct used a geographic information system app (Arc GIS). The Arc GIS output is of several maps of hazard, vulnerability, capacity, and tsunami disaster risk in the Jember Regency Coastal Area. The research result of the tsunami disaster risk assessment showed that six villages had high risk from twelve coastal villages in Jember Regency.
