Abstract
GIS hardware and software can assist in assessing the condition and value of land based on various factors such as accessibility to infrastructure, soil fertility, etc. Currently, it is man-made and environmental disasters that have the greatest impact on the condition of the soil and the availability of infrastructure. In the paper, the authors investigate the methods of recording disasters using GIS technologies and the impact of disasters on the land resources evaluation. A sequence of steps has been developed, with the help of which various GIS programs (QGIS, ArcGIS Pro - Esri, Digitals, online GIS services) can be used to establish the impact of disasters on the condition of land resources. GIS functions (Databases, Data analysis, Machine learning, Modelling) allow to study how disasters affect investments and development. Demand and supply on the land market and its valuation depend on them. The possibility of using and integrating different types of input data was investigated, a combination of channels of multispectral satellite images and radiological data on the topography of the area. It is indicated which characteristics of the resources condition are more affected, for example fixation of the dam destruction, shallowing of the reservoir and fires. Man-made and environmental disasters, as well as the distance to the combat zone, are currently one of the main factors that affect the ecological condition and economic evaluation of land resources. GIS functions allow to record changes caused by disasters, to study trends, recovery options, use of objects and territories that have been affected. Indicators obtained with the help of GIS technologies are further used for ecological and economic assessment of land resources.
