A modern map of plant cover technogenic disturbance (M 1:200 000) for the Nenets Autonomous District was prepared in ArcGIS using field data (2001–2016) and satellite images Landsat-8 and Sentinel-2 (2014–2016). The current state of plant cover within the technogenic objects and their buffer zones was compared with that in the surrounding area. Three categories of objects were identified depending on the size and spatial orientation of the technogenic disturbances: point, linear and polygonal (area). The vector layer for each category was generated in ArcGIS. Each object was categorized when deciphering satellite images. GIS allows us to assess the degree and intensity of any territorial division disturbance (geobotanical, oil fields, municipal, protected natural areas, etc.). The calculated area of plant cover technogenic disturbance is less than 1 % for the whole territory Nenets Autonomous District, whereas it reaches 2 % for the Kharyaga geobotanical region and 8 % for the Pripechorskiy (because of the broad buffer zones in neighborhood of Naryan-Mar and small settlements, numerous dirt roads, recreation areas, etc.). The vegetation cover of such sites is transformed to some extent and differs from adjacent natural communities. The prepared map will serve as the basis for the organization of remote monitoring of plant cover. The map was delivered to the Nenets information and analytical Center of the Nenets Autonomous District Administration.
