For the last 8 years, the Russian space constellation has lacked spacecraft capable of radar imaging. The previous satellite equipped with such imaging equipment was decommissioned in April 2015, and it took a long period of time to build new ones to replace it. This type of imaging equipment differs significantly from the usual optical-electronic imaging equipment. Despite a number of advantages, these spacecrafts have some disadvantages. In this paper the differences between these types of spatial data acquisition are considered, including those caused by different methods of survey equipment installation. The influence of weather conditions on the received terrain images was studied, for this purpose 2304 images were analyzed at 17 control areas in different parts of the Russian Federation. The possibility of using images from radar satellites for application in cadastral activities was assessed based on the requirements to accuracy and methods of characteristic point coordinates determination (accuracy values (mean square error) of characteristic point coordinates determination for land plot boundaries) formulated in Annex 1 of the Order of the Federal Service for State Registration, Cadastre and Cartography No. P/0393 dated October 23, 2020, and during implementation of federal projects using the example of the Northern Sea Route development program.
