Iranian Remote Sensing and GIS Society / Shahid Beheshti University Iranian Journal of Remote Sensing and GIS 2008-5966 14 3 2022 09 23 Preparation and Verification of Poplar Plantation Mapping Using Satellite Data of Sentinel-2 and Ground Data in Zanjan Province Preparation and Verification of Poplar Plantation Mapping Using Satellite Data of Sentinel-2 and Ground Data in Zanjan Province 1 14 101652 10.52547/gisj.14.3.1 FA Mahmoud Bayat Assistant Prof., Research Institute of Forests and Rangelands, Agricultural Research, Education and Extension Organization (AREEO), Tehran Khosro Mirakhorloo Research Instructor, Research Institute of Forests and Rangelands, Agricultural Research, Education and Extension Organization (AREEO), Tehran Hosein Sadeghzadeh Research Expert, Research Institute of Forests and Rangelands, Agricultural Research, Education and Extension Organization (AREEO), Tehran Sahar Heidari Masteali Ph.D. of Environment, Faculty of Natural Resources, University of Tehran Journal Article 2020 09 22 Lack of up-to-date, documented and scientific information on the current situation (area and distribution) of Zanjan poplar plantation<strong> </strong>is one of the main problems of wood production managers for planning and management of wood supply in the province and the country. In this study, Sentinel-2 satellite data with spatial resolution of 10 m in spectral bands were used and the ground truth map of existing poplar fields with 600 points was plotted in all cities and villages from field surveys. From the beginning to the end of the poplar growing season (first half of March to December 2018), at least 6 time periods of 30 to 40 days were used in the SVM classifier. Post-test and calibration of SVM model based on the phenology of poplar genus and field samples were extracted, populated area distribution map of province was extracted. The results showed that the total area of ​​poplar areas is 2744 hectares which covers 0.12% of total area of ​​Zanjan province. One percent of the total polygons were randomly selected for field control and after field control, the overall mapping error was obtained and calculated. In this study, the exact location and area of ​​poplar mills were estimated with acceptable accuracy (96%). So that using extracted information (distribution map of poplars of the province) can provide studies on comprehensive planning of poplars and sustainable management of wood production from the poplars of the province.
