Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The work is devoted to the technique of mapping of cultivated and abandoned croplands in areas of the European territory of Russia of different climate, landscape and geomorphological conditions.A technological scheme of croplands visual interpretation based on Landsat 5 and 8 multi-seasonal images for two time slices (mid-1980s and the modern period of 2013-2015) is described.Classification keys of various types of croplands are introduced: spring crops, winter crops, fallow, abandoned croplands.A technique of croplands digitizing based on the principles used in the CORINE Land Cover 2000 (CLC2000) project is presented.Vector layers of cultivated croplands for the two considered periods are obtained.Validation of the results based on high-resolution satellite imagery is performed.
