The article discusses the use of space imagery data from spacecrafts of the russian-belarusian spacecraft constellation intended to control natural and industrial disasters, land use, forestry, ecology and provide free access to geospatial content.
Key words: space imagery, Earth remote sensing data («ERS» data), land use control, emergency, forestry monitoring.
After deployment of the satellite cluster in 2012 consisting of the Belarusian spacecraft ("BS") and "Canopus-B» №1 spacecraft, the national operators started to supply the ERS data to the public consumers of operational hydrometeorology, entities monitoring natural and industrial disasters, those of environmental resource management, ecology and cartography.
Table 1. Contains main characteristics of the spacecraft and its optoelectronic facilities.
Later on, in order to improve the economic benefits of running the satellite cluster, it was decided to establish a joint venture for the commercial use of ERS data and promote it to the Russian and international markets. In February 2014 by order of the Deputy Prime Minister of the Russian Federation Mr. D. Rogozin and Government regulation of the Republic of Belarus was formed a joint Russian-Belarusian compa-
ny "International space technology." This has laid foundations for the partnership between Russian and Belarusian enterprises in the field of commercialization of space activities.

The founders of the joint venture are: on the Russian side - JSC "VNIIEM Corporation", developer of the meteorological satellites such as" Meteor-M "and small ERS spacecrafts such as" Canopus-B ". On the Belarusian side it is "Geographic Information Systems" Unitary Enterprise, the operator of the Belarusian ERS system.
JSC "MKT" main activities:
1. Commercial distribution of ERS data and its processing results got from the BS and "Canopus-B" spacecraft as the exclusive sales representative "GIS" Unitary Enterprise in the CIS countries excluding the territory of the Republic of Belarus.
2. Photogrammetric and subject based data processing of ERS data from the BS and "Canopus-B" №1 satellite, byproducts: orthophotoplans, mosaics of space images, digital elevation models, etc.
3. Development and updating of specialized geo information systems.
Types of products supplied by JSC "MKT" can be seen in Table 2.
Under the terms of the multiagency agreement Roscosmos and the National Academy of Sciences of the Republic of Belarus share the spacecraft cluster of two satellites to provide Russian and Belarusian consumers with the ERS data and its processing results. Images from "Canopus-B» №1 and Belorussian satellite are supplied to consumers of space information in three processing levels resulting in the following types of the final product, "base product"; "Standard product" - the image in a
given map projection with radiometric processing, sensor distortion correction and geometric correction; "Orthorectified product" - ortho-images, digital maps and digital elevation models.

Each ortho-corrected image is radiometrically calibrated and geometrically and topographically improved according to high-accuracy measurements of the orbital parameters as well as according to Ground Control Points ("GCP").
EMERCOM of Russia its National Center for Crisis Management have successfully realized a ground computer based system for "Canopus-B" to receive and process data, intended to detect flooding and forest fires situations, to evaluate the infrastructure condition after significant earthquakes, natural and industrial disasters.
Fig. 1 and Fig. 2 represent instances of common use of satellite images for the above tasks.

Fig. 1. Monitoring of emergency situations
A pioneering Russian experimental technology to process images using rational polynomials (RPC) was developed for "Canopus-B» №1 and Belarusian spacecraft,
which can be used to perform rough image conversion, independently of ground control points. Terrain Information is taken from SRTM public digital elevation model. For adjustment purposes the image scenes and orthophotoplans can be based upon ground object forms with coordinate readings imported from GLONASS technologies or appropriate map scale data from cartography-geodesic fund. The GIS "Map 2011" software with its "Raster map points" tool can be used to locate the image size.
Information, obtained from the "Canopus-B» №1 and Byelorussian satellite is used to monitor the land use in agro-sector, natural resources control and eco-control, ground mapping needs. Some examples of the use of ERS data taken from the spacecraft are shown in Fig. 2.

Fig. 2. Monitoring of land-use objects, forestry, eco-control and ground mapping
Starting from 2012 the Federal Forestry Agency has been using ERS data from satellites "Canopus-B» № 1 to control forest areas and identify illegal forest cutting, as well as to perform contracts of forest inventory and while putting the forest plots on cadastral record.
Fig. 3 shows examples of forest control (deforestation control) in panchromatic view and images from the "Canopus-B» № 1 in 2013. For comparison «Google Maps» images of the same area are provided.

Thus, the space imagery data from BS and "Canopus-B» №1 spacecraft has been efficiently used both in Russia and in the Republic of Belarus to provide real-time monitoring of hydro meteorological objects, monitoring of natural and industrial disasters, environmental resource management, ecology, and for the purposes of digital and topographic and navigation mapping.
