MENTHA CROP ASSESSMENT USING MULTIDATE REMOTE SENSING DATA: A CASE STUDY FOR BARABANKI DISTRICT, UTTAR PRADESH

摘要

Mentha (Mentha arvensis) area assessment was carried out for Barabanki district, Uttar Pradesh, under the CHAMAN project, for the year 2015-16. Mentha is generally grown from March to June in this area. The major crops, other than Mentha were Orchards and Vegetables. Multidate Resourcesat-2 LISS-III data during March to May 2016 was used for crop area assessment, crop condition monitoring and crop phenology study. Ground truth (>50 sites) was collected during May, 2016 for crop signature identification and validation. A combination of unsupervised and supervised classification of multi-date NDVI data was used for area estimation. Crop area was separated into different health classes, based on NDVI values. The multi-date data also helped to identify the maximum vegetative stage, which can be useful information for harvesting. The Mentha area in the Barabanki district has been estimated around 67627 ha. The accuracy of the estimation was verified with the data of State Horticulture Department, Government of Utter Pradesh for the same year. The deviation has been observed around 0.43 %.
