Development of demographic mapping method based on GIS technologies

Abstract

Nowadays we can clearly see the activeness of the methodological and technological aspects of the new geoinformation direction in the field of cartography. The development of modern mapping methods is closely related to the development of geoinformation systems and technologies. The importance of geoinformation cartography and geoinformation systems is significant in creating databases and digital maps based on GIS software instead of analog methods for creating maps. There are the most important tasks such as improvement of modern method in obtaining cartographic information, and development of ways to quickly transmit and distribute cartographic information about nature and society. The application of GIS technologies in the field of demographic cartography will lead to drastic changes in the scope of work, as well as improve product design and increase the accuracy as a result of the performed tasks. The study shows that there is a need to develop a new method for mapping a new generation based on GIS technology, reflecting demographic processes. This article will focus on creating a database for development of maps based on GIS technologies, rapid identification, monitoring spatial changes using data from aerospace and other sources, and development of demographic digital mapping methods based on GIS technologies. Mapping demographic processes based on GIS technologies aims at implementing a number of practical tasks and research related to population. Based on this, a systematic method has been developed to analyse the demographic situation in the southern region of the Republic of Uzbekistan, and a digital demographic map has been created by applying the developed method.

Review of mapping regional demographic processes using innovative methods and technologies

“…A population map of the southern region was then constructed using cartographic mapping methods (Fig. 10) [10].…”

“…NDVI was calculated using NDVI = (IQ-Q) / (IQ + Q) the formula [8,[10][11][12]. In this case, IQ is the infrared spectrum of the image; Q is the red spectrum of the image.…”

“…With the introduction of innovative technologies, statistical information relevant to the population based on new data on the ground can be received online from local officials and integrated with a geo-data database, which allows to constantly monitoring the dynamics of the population. At present, almost all maps are created using GIS technologies, and interdependence and integration of geoinformatics as well as cartography can be easily seen in a mapping process [10,13]. It is stated that the interrelation of cartography and geo-informatics in demographic map can be seen in the following stages [3]: 1) in GIS programs, linking spatial data to a single coordinate system, and using a large-scale topographic maps; 2) entering remote sensing data and other information (statistical and analytical) used in GIS software into computer memory; 3) Vectorization of data in the form of digital maps to form a component of GIS technology databases; 4) stratification of the thematic structure of spatial objects.…”

Development of a method for determining the optimal areas for alternative energy facilities based on GIS technologies

“…For Samarkand province, 5 classes were obtained from 250 meters to 2,500 meters, while for the Tashkent province 5 classes were determined from 200 meters to 4,000 meters. [11,16] Based on the results of the classification, an algorithm was developed using the ArcGIS software, as well as suggestions and recommendations were made for choosing or determining the most optimal location for solar panels and wind turbines (table 2). Acceptance levels were divided into 4 types, as shown in table 2.…”

Possibilities of organizing agro-touristic routes in the Fergana Valley, Uzbekistan

“…The area is surrounded by mountains. The region is surrounded by Turkestan and Alay in the south, Fergana and Otoynak in the east, Chatkal in the north, Qurama and Karamazor mountain ranges in the northwest, and Mugultog in the west [8][9][10][11].…”
