The article presents information about methods and technologies used in assessing the dynamics of urbanized territory, gives a brief description of them, and identifies advantages and disadvantages. The concept of geoinformation monitoring of an urbanized territory is formulated. To integrate heterogeneous and multiformat data and assess the dynamics of residential environmental management, a problem-oriented GIS for monitoring urbanized territories has been developed on the example of Ulan-Ude city (Republic of Buryatia). The functional structure of GIS, consisting of measuring, analytical and cartographic blocks, is presented, and the characteristics of each block are given. The planned basis of GIS is the topographic basis of three spatial levels: regional (1:200 000) for monitoring agglomerations and large cities; local (1:50 000, 1:100 000) to assess the dynamics of residential development of the territory; detailed (1:10 000, 1:25 000) to assess the dynamics of real estate and land plots. A digital terrain model is used as a high-altitude basis for the assessment of urbanized territories, which allows the assessment of morphometric parameters of the residential nature management system. The dynamics of the urbanized territory of Ulan-Ude was estimated using six time sections. The physical and geographical features of the urbanized territory development are determined, the map of the city dynamics for the entire period of residential development is compiled, and the forecast of the further development of the urbanized territory for background and local buildings is presented.

Flat studies showing terrain (e.g. in form of maps) do not fully reflect its nature. Planning or design projects are definitely better represented in three-dimensional space. Previously used “sand tables”, especially popular in military applications, are expensive and uncomfortable to use due to their large size. In addition, they are modifiable only to a small extent and do not provide such accuracy as traditional maps. With the development of modern model relief techniques, a spectrum of the possibilities for development of customized spatial models (defined as models of the surrounding reality, mapped in the appropriate scale in three dimensions), has increased. The aim of this article is to present the possibilities of using 3D printing for the visualization of a mountain. Based on the digital terrain model (DTM), a model of a part of the Tatra Mountains was developed. It was established by DTM data processing and printing on a 3D printer using the FDM (Fused Deposition Modeling) technology. This article describes the principles for developing such a model and the advantages and disadvantages of the proposed solution. Keywords: cartography, digital terrain model, sand table, FDM technology

The city of Kenitra, located in the extreme downstream of the Sebou basin, is threatened by floods caused by the overflowing of the Oued Sebou and the rise of Oued Fouarat. The hydraulic modeling study of the Sebou Fouarat system in transient mode is carried out by the HEC-RAS software and has implicated the two rivers. Two geometric models were constructed on the basis of a digital terrain model (DTM) using the Arc-GIS and HECGeoRAS softwares after processing the collected topographic data. The first model, of which the areas of Merja Fouarat and Al Assam have been represented by cross-section, is one-dimensional. The second one is also onedimensional in which the two areas of Merja Fouarat and Al Assam are introduced as water storage zones. The components of these models are the stream sections, lateral links, storage areas and junctions between the branches of each model. The flood hydrographs of the Sebou and Fouarat rivers are introduced as conditions at the upstream limits of the models while the tidal is introduced as a downstream condition. After the stability and calibration of the models, the results of the consulted hydraulic simulations are the variations of the water levels as well as the temporal variations of the flow rates for each section, the maximum flow velocities and the propagation times of the flood waves. The analysis and comparisons of these results strongly suggest using the second model for the treatment of the flood issues as a decision-making tool helping to manage floods during times of crisis.

The study area focuses on three cases of study in the Veneto Region: the city of Adria, the village of Pettorazza Grimani, both located in the Rovigo Area, and the Sant’Ilario community in the Mira District on the southern border of the Venice Lagoon. The multidisciplinary approach (archaeological, geological, geographical and historical) used in the geoarchaeological research discussed in this paper is based on the study of written sources, historical cartography, aerial photographs, digital terrain model, archaeological and geological data. The analysis highlights the interaction between anthropic and environmental changes realised during centuries and the key role of the hydrography in constraining land use dynamics in the landscapes of plain.

Processing and interpretation of July 2007 digital visible and near-infrared aerial photographs, coupled by a digital terrain model, has allowed for detailed reconstruction of the topography and the paleoenvironmental setting of the Roman city of Altinum, shedding new light on the far origins of Venice. Images were taken during severe dry conditions, which stressed the maize and soy crops. The city walls and doors, the street network, dwellings, theaters, amphitheater, forum, emporia, basilica, and a complex network of rivers and canals have been mapped.

At present, in Kuzbass, various methods of automation of plane surveys in open mining are used. In most cases, the choice of method depends on the material base of the enterprise and the professionalism of the performers. Typically, the work on the surveying automation consists in using electronic tachometers, which reduce time and simplify field and office work. However, the use of electronic tachometers remains the human factor and does not allow solving the problem of displaying the situation throughout the open pit at one physical moment of time. Aerial photography (AP) significantly increases the performance of plane surveys and makes it possible to most fully and reliably display the information about the surface and ensure the safety of fieldwork. The article presents a comparative analysis of the accuracy of constructing a digital terrain model obtained during aerial photography by AN-2 aircraft and instrumental survey performed with electronic tachometer Leica TS 06 plus, by example of surveying a trench of section № 1 at Olzherassky open pit in the Kemerovo region. The advantages and disadvantages of AP from an airplane and prospects of using AP from an unmanned aerial vehicle (UAV) are given.

Flooded Areas

Wargames have been promoted by local governments in Taiwan since 2009, as they require far fewer resources than full-scale exercises. Previously, wargame scenarios were divulged before their launch, enabling participants to formulate response plans in advance, which made them ineffective. Currently, wargames in which scenarios are not shared in advance require a common platform for debriefing players regarding their planned actions. Owing to its geographical location, Taiwan is prone to significant flooding disasters. To assist in making countermeasures, we created a 3D GIS-based Flood Wargame Assistance Platform (FWGAP) for conducting rapid spatial analyses. Flooded areas are estimated in the FWGAP in three ways: (1) using a digital terrain model (DTM) with designated flood center and depth; (2) applying historical flooding spots; and (3) potential flooding maps. A FWGAP can estimate affected and vulnerable populations and has functions for locating resources such as shelters and hospitals near the flooded areas. Its integrated use of closed-circuit televisions, Google Street View maps, and 3D buildings to display flooded areas realistically ensures greater fidelity. This study reports on the city- and the district-level applications of the FWGAP. The results of the survey undertaken indicates that 56% of the participants agreed that the FWGAP enables disaster relief resources to be located on a GIS map. About half of the participants believed that a no-script flooding wargame using a FWGAP could help to identify problems in standard operation procedures and promote greater horizontal coordination among departments.
