Abstract

The paper examines the issues of integrating geodata from different sources for geoinformation mapping of the transformation of rural settlement. The object of the study is the change in the population settlement network in the Khorezm oasis and the Fergana Valley of Uzbekistan. The study is based on the use of materials from official state statistics on the population in the context of individual settlements, cartographic materials and satellite imagery, and the results of field surveys for geoinformation mapping. An algorithm for geoinformation research of changes in the area and population of settlements over 1959-2023 is proposed. OpenStreet Map geodata are used as a base map, the detail and geometric accuracy of which are sufficient to calculate the quantitative characteristics of the transformation. Multi-temporal topographic maps at a scale of 1:200,000 for 1959, 1979 and 1989 are used to create geodata in vector format. Geocoding of source materials was carried out to form a database consisting of blocks for several dates. The results of the automatically calculated areas of each settlement were used to calculate their growth. Remote sensing materials, in particular, space materials obtained from the Landsat satellite for 1994, Landsat / Copernicus Data SIO, NOAA, U.S. Navy, NGA, GE- BCO April 10, 2013–December 14, 2015, October 4–December 14, 2023, and posted on Google Earth Pro, are used to update data geometry. ArcGIS Online services are used for interactive mapping. Data on the population of each locality on the indicated dates were used to calculate growth for the periods 1959–1979, 1979–1989, 1989–2023. Based on the results of the study, it is concluded that at certain stages of development the transformation process is characterized by qualitative and quantitative changes in the settlement network. Methods of geospatial analysis were used to identify changes in the types and forms of settlement that characterize the features of the transformation.
