Use Of Knowledge

Аbstract. Problem. The article reveals the use of knowledge of astronomy in engineering calculations when planning urban development in the 18th - 19th centuries. Goal A solar calculator from the SunCalc program was used in the study. It was proved by the example of the ancient buildings of St. Peter's Square in the Vatican that architects in ancient times madeaccurate calculations for the planning of streets and cities and used astronomical knowledge Thanks to the use of modern GIS technologies, it has become possible in our time to superimpose the existing buildings on a satellite image of the territory of the ancient buildings and see that the line of St. Peter's Square completely coincides with the line of the sun, directed at the vernal equinox - March 22. Methodology. The building line of the square - the beginning and end of the buildings, consisting ofcolumns, coincides with the line of the sun's rays directed to the days of the summer and winter solstices. This suggests that the architectural planning of the development of ancient cities was carried out with calculations according to the laws ofthe ecliptic, with knowledge of physical and mathematical calculations and all streets and arched vaults were aimed at the passage of sunlight on certain days in certain places, as if illuminating buildings and squares. Modern urban developmentplanning should be carried out using GIS technologies and mathematical modeling. Results Modern urban development must take into account historical architecture, areas of historical events and protected areas. The stylistics in the design must berepeated and the development planning must be carried out in a single architectural ensemble of the city. This will attract tourists and financial investments to us.

The Status

Urban vibrancy is the key and the foundation for monitoring the status of urban spatial development, assisting in data-driven urban development planning and realizing sustainable urban development. Based on a dataset of multisource geographical big data, the understanding and analysis of urban vibrancy can be deepened with fine granularity. The working framework in this study focuses on the comprehensive perspective of urban morphology, which is decomposed into two dimensions (formality and functionality) and four elements (road, block, building, point of interest). The geographically and temporally weighted regression model was first applied to determine the spatiotemporal effect of the morphological metrics on vibrancy, and then, the geographical detector was employed from the perspective of spatially stratified heterogeneity to reveal the synergetic impacts. The following findings were revealed. (1) Dense street networks, small and medium-sized blocks, and the diversification and intensification of building and land use are beneficial to urban vibrancy. (2) Under the premise of adapting to local conditions, urban spaces combine multiple morphological metrics for the accomplishment of a full-region and all-time vibrancy. (3) The mixture of urban functions is worthy of attention for vibrancy growth because of its extraordinary synergy, not its capacity. Morphological metrics serve to foster and prolong urban vibrancy, adapt to urban sustainability, and contend against inefficient, disorderly urban sprawl. These findings provide significant implications for urban planners/designers and policymakers to optimize urban morphology, improve the vibrancy in large cities, and implement high-quality city planning.

Environmental education is an important function of Protected Areas among them nature reserves. It includes development of visible and available materials on tours and routes, on geographical and environmental features of a territory, and on unique species of flora and fauna. Interactive map of vegetation “Along Doppelmair’s trail” is an example of scientific information visualization. It was made for a distant and restricted core area in Barguzinsky Nature Reserve. We applied traditional geographical approaches and methods (field research, geobotanical descriptions) and modern GIS technologies (creation of unit database on landscape foundation, satellite image interpretation, infogram visualization) to create the map. As a result a GIS product is created with ArcMAP and located on the ArcGIS Online platform. This map shows characteristic vegetation types, succession stages of pyrogenic dynamics of forest geosystems formed during a century period. Infograms demonstrate information on sites with wild animal encounters, vegetation distribution, landscape features, and photographical materials. This interactive map is a way for environment protection popularization and solving some educational tasks for Protected Areas. It gives an opportunity to study changes in vegetation from Lake Baikal shoreline to mountain peaks of Bаrguzinskii Range, learn typical flora and fauna species, including endangered ones, find interesting historical facts about the reserve, and, thus, get an idea of uniqueness and fragility of nature and the importance of protection attempts.

Nighttime Light

Quantitative and accurate urban land information on regional and global scales is urgently required for studying socioeconomic and eco-environmental problems. The spatial distribution of urban land is a significant part of urban development planning, which is vital for optimizing land use patterns and promoting sustainable urban development. Composite nighttime light (NTL) data from the Defense Meteorological Program Operational Line-Scan System (DMSP-OLS) have been proven to be effective for extracting urban land. However, the saturation and blooming within the DMSP-OLS NTL hinder its capacity to provide accurate urban information. This paper proposes an optimized approach that combines NTL with multiple index data to overcome the limitations of extracting urban land based only on NTL data. We combined three sources of data, the DMSP-OLS, the normalized difference vegetation index (NDVI), and the normalized difference water index (NDWI), to establish a novel approach called the vegetation–water-adjusted NTL urban index (VWANUI), which is used to rapidly extract urban land areas on regional and global scales. The results show that the proposed approach reduces the saturation of DMSP-OLS and essentially eliminates blooming effects. Next, we developed regression models based on the normalized DMSP-OLS, the human settlement index (HSI), the vegetation-adjusted NTL urban index (VANUI), and the VWANUI to analyze and estimate urban land areas. The results show that the VWANUI regression model provides the highest performance of all the models tested. To summarize, the VWANUI reduces saturation and blooming, and improves the accuracy with which urban areas are extracted, thereby providing valuable support and decision-making references for designing sustainable urban development.

The Status

The paper provides a comprehensive analysis of urban development trends in the Latgale region, observed at the beginning of the 21st century and to a large extent also outlines the direction of future development. The paper is based on the evaluation of spatial development planning documents,the analysis of the available statistical data and the review of the urban development projects subject to implementation, supplemented by some results of field studies on the urban environment quality. Though the urban environment and partly also the landscape quality has been improved during the last period, as well as in many areas with support of the EU programmes major urban environment development projects are being implemented, however the economic growth is stalling, depopulation processes are not contained, and the regional urban development index is expressly negative. In the course of the administrative and territorial reform the status of the majority of towns and cities of the Latgale region has significantly changed, and sustainable urban development in the region is still under real threat.
