Satellite imagery / Satellite data - one of the methods of remote sensing of the Earth surface by means of spacecraft located in orbit and allowing obtaining images of the terrain in visible, infrared and radio bands of the spectrum with specified parameters and characteristics.
Remote sensing of the Earth - observations and measurements of natural and reflected radiation of land, ocean and atmosphere of the Earth in different ranges of electromagnetic waves by means of specialized equipment installed on spacecraft and other aircrafts for the purpose of detecting changes, location and temporal variability of natural phenomena, Earth objects, the environment and anthropogenic objects.
Satellite imagery / Satellite data is the most efficient and cost-effective way to obtain spatial data. Modern space images have high measuring and imaging properties and are presented in digital form. The spatial resolution of space images reaches 30 cm and the accuracy of orbital positioning is 2.5 m, which enables to solve various tasks of the state, science and business.

New and archived space imagery is ordered through authorized partners of space imagery operators.
Space imagery - an objective and independent information source!
- analyze socio-economic development of territories;
- to track the dynamics of changes in the area
- acquisition of information regardless of the object of interest location
- use both archived and fresh information;
- detect objects and events with high accuracy;
- creation and updating of topographic maps and plans, as well as other cartographic products;
- creation of engineering-topographic maps during engineering and geodesic surveys;
- creation of remote basis of geological maps;
- assessment of the situation on the ground for a certain period of time including dynamics of changes;
- monitoring of changes on the ground in the time lag mode from 30 minutes;
- business intelligence;
- expertise on the basis of space images as evidence in court;
- creating engineering and geological maps in geological surveys
- execution of land surveying and cadastre works;
- creation of digital terrain models for planning and development of telecommunications networks;
- agricultural research, identification of plant diseases, determining the phase of vegetation;
- conducting industrial and environmental monitoring.
- administrative-territorial management, creation and maintenance of urban and land cadastre.
- monitoring of emergency situations and their consequences, control of the course of emergency and recovery works;
- and many other tasks.
- Benefits of Using Space Imagery Data
- Super-high resolution and high resolution space imagery data can be acquired more expeditiously as they may already be in the operator's archives and the new imagery does not require any coordination with the state agencies. The area of this image is much larger than that of an airborne or UAV image.
Another indisputable advantage of space imagery is its objectivity (the human factor is minimized).
The image of the Earth is constantly changing and any map is gradually aging. Space images contain up-to-date and reliable terrain data and are successfully used for updating maps not only at small, but at large scales as well. They allow correcting maps of large territories of the world. Space imagery is especially efficient in hard-to-reach areas where fieldwork is very labor- and cost-consuming.
