Development and use of gis database for tasks of normative monetary evaluation of land of settlements

The paper presents the results of research on the development of a GIS database for the tasks of normative monetary valuation of lands of settlements and highlights the applied aspects of its use on the example of Lychanka village, Dmytriv territorial community, Bucha district, Kyiv region. An algorithm for developing a GIS database for normative monetary valuation of settlement lands is presented. The presented estimation algorithm allows to carry out with high accuracy normative monetary estimation of settlements, to carry out its automated updating on a certain date, to receive necessary information on request, to carry out analytical operations and construction of specialized estimation maps. The development of the GIS database involved the implementation of two stages. At the first stage of formation of the initial land assessment base, the attribute table included data from the Public Cadastral Map of Ukraine on land plots within the settlement by the following items: cadastral number of land plot, area, form of ownership, purpose and functional use of land plot , the number of the cadastral zone in which each land is located, the number of the land assessment area of the settlement, the value of the base value of land, the value of the zonal coefficient (Km2), the coefficient characterizing the functional purpose of the land (Kf), information on the location (street name). The second stage involved the calculation of the value of the normative monetary valuation of each of the 1279 land plots and was performed using the built-in Arc Map function "Calculation of numerical values". After the development of the GIS database, the testing stage of the developed land assessment database was performed, which involved the use of various query execution, geospatial analysis, the use of buffering functions, topological overlay (intersection). As a result of the analysis, the following maps were constructed: "Influence of local factors on the distance of land from the center of the settlement", "Influence of local factors on the distance of land from highways", "Influence of local factors on the environmental situation", "Influence of local factors on security electricity", "Influence of local factors on the distance from paved roads", "Influence of local factors on the provision of centralized water supply", "Influence of local factors on the provision of centralized sewerage", "Influence of local factors on the provision of centralized gas supply", "Map plots according to the results of normative monetary assessment" , "Map of the establishment of buffer zones by the value of local coefficients" , "Map of coastal protection strips around water bodies with the allocation of zones of their intersection with land". Due to the application of special functions of geospatial analysis available in the GIS environment, examples of development of highly informative cartographic materials in the form of special pricing zoning of the territory of the settlement are shown. The expediency of the application of the GIS database for the tasks of monitoring the quality of land, compliance with their legal regime and the possibility of monitoring the implementation of fiscal obligations by landowners and users.

30 Years Climate Change Impact on Weather Elements and Green Coverage: GIS and Remote Sensing Geo-Environmental Case Study in Jordan

This study deals with climate change and its geo-environmental impact in Jordan for thirty years period (1982-2012). It comprised the building of a geographic information system (GIS) database for the most important basic climatic elements of temperature, rainfall, and relative humidity. Data is obtained from the Meteorological Department of Jordan for the study period. Digital descriptive and statistical analysis methods for the GIS database are implemented using ArcGIS 10.4 software and Normalized Difference Vegetation Index extracted from Moderate Resolution Imaging Spectroradiometer satellite images to forecast that impact on weather elements and green vegetation cover, respectively. Three different criteria are used for analysis and verification to achieve the objectives of the study. The criteria are the average annual minimum and maximum temperature, which is considered the most important criterion for this study, average annual rainfall, and average annual relative humidity. Results showed a speedy increase in the annual rate of the local temperature, particularly since 1990. Despite the local temperatures' average volatility, the increment reached about 1.5-2.0 oC degrees Celsius. An increase in the relative humidity is observed, but with no evident change in the average annual rainfall, both in Jordan's northern and eastern parts. At the same time, there were increases for Jordan's central region during the period 1985-2012. The green vegetation cover area showed a decrease during the studied period 2002-2008 as that is probably due to the evident increase in annual average temperature and evaporation. Results reveal the increase of the greater temperature change region has increased in the northern part of Jordan by eight times for the 1982-2002 period as mentioned in this study. The area of vegetated area decreased to 3725.8 km² in 2008 compared to 9305.5 km² in 2002. The study demonstrated efficiency in applying descriptive and statistical GIS analysis methods on the climatic database, which better understanding of the climate change phenomenon.

CRITERIA AND TOOLS TO CATALOGUE BRICK-MASONRY VAULTS. THE GIS-DATABASE OF FRAME, A FASCE AND PLANTERIAN VAULTS BETWEEN THE 16TH AND 18TH CENTURY IN NORTHERN ITALY

The paper describes a proposal for criteria and tools to catalogue brick-masonry vaulted systems in Northern Italy between the 16th and 18thcenturies. Along with the standard geometric typologies, three novel parameters (maîtresses voûtes, voûte sur le plan d'une autre voûte, constructive features) are proposed to include the constructive features in the vault taxonomy. The novel parameters help catalogue three vaulting types that can be considered the metamorphosis of cloister vaults: frame, a fasce, and planterian vaults. The database was realized in MS Access and then imported into QGIS 3.10. Database and GIS have been operative tools to form hypotheses on vault disseminations, highlighting the recurrences and specificities across time and space of some peculiar construction techniques. The database collects the acquired information on each vault (building type, geolocation, building date, vaulting type, vault dimensions and description and, whenever possible, photogrammetric survey, 3D modelling, and thermographic survey). In the future, the database should be published online, making the data available and building a broader dataset to share the information.
