Tea Acreage Estimation and Condition Assessment Using Satellite Data in Nilgiris District, Tamil Nadu
In the present study, an attempt has been made to estimate acreage and condition of tea plantation by using satellite based digital remote sensing data in the Nilgiris district of Tamil Nadu. Temporal satellite data of MSS AND TM were used for identification of tea plantations. District boundary – overlaying approach with a complete enumeration of digital data were used for the estimation of tea acreage. NDVI images were generated to assess the condition and vigor of tea plantations. Results indicate that approximately 18,785 hectares of the forest area converted with a simultaneous increase in the area of tea plantations from 28,252 hectares to 47,038 hectares. Results of the present study indicate that improved Spatial and radiometric resolution of the Land sat satellite data can be advantageously utilized for differentiation of tea plantations and also an assessment of vigor of tea plantations. The impact of conversion of forests to plantations can have a long term adverse effects on the ecology and environmental conditions of the forest ecosystem.
