Maintaining the state cadaster of the territories on the base of remote sensing materials

Abstract

In the past, remote sensing was limited to the use of the visible part of the electromagnetic spectrum, the part of the spectrum that is invisible to the human eye can now be used with the help of spectral filters, photo films and other types of sensors. Also, the view of the earth was applied to practice and to solve life problems, for example, we can cite air reconnaissance during World War II. Aerial photographs provided the opportunity to observe the location of the enemy's army quickly and more safely than observation from the ground. Aerial photographs allowed military maps and information about strategic locations to be updated quickly and with relative accuracy. Remote sensing is carried out from the air by airplanes and with the help of satellites. Digital cameras, scanners, video images, radar and thermal sensors are also used in remote sensing. Remote sensing is a field that requires fast, accurate and new data collection and is widely used in environmental management. This article presents the stages of creating topographical bases for maintaining state cadastres in the Tashkent region, taking space photos, taking aerial photos, performing geospatial linking, vectoring, and creating electronic digital maps. At the same time, scientific research such as filling the attributes of electronic digital cards and comparative analysis of space photo download sources has been reflected.
