Multi spectral images as more informative are mostly used in ecological research. The part of it is provided free and the other is based on the contract. The cost of such images depends on the special parameters.
Earth remote sensing data use actuality are explained by advantages of such data. They are the following:
- Supported information reliability
- Relatively big coverage of the territory under survey
- Periodical updating of the images
- Relatively easy access
The one of the most successful project of Northern Geographical Company in the ecological monitoring is the complex ecological estimation realization of Lebedinsky Mining and Processing Integrated Works territory. The company’s specialists realized the complex works on geo-spatial basis preparation over LGOK territory, including analysis and selection of optimal source remote sensing data suitable for the project’s goals, orthorectification, interpretation, creation of geo-information layers and attribute database.
