GI3027 Geomatics for Agriculture and Forestry Syllabus – Anna University Regulation 2021

COURSE OBJECTIVES:

 Through this course students can learn about remote sensing and GIS techniques to use in a variety of applications related to agriculture,soil, land and forest resources.

UNIT I CROP INVENTORY AND REMOTE SENSING

Introduction-leaf optical properties-identification of crops and crop inventorying–crop acreage estimation-vegetation indices-yield estimation-crop production forecasting through digital analysis – microwave and hyper spectral sensing for crop inventory –crop monitoring and condition assessment – case studies.

UNIT II REMOTE SENSING FOR SOIL

Introduction-soil survey, types of soil surveys-soil genesis and soil classification –soil taxonomy-soil reflectance properties-soil mapping using remote sensing–problem soils-saline, alkali soil characteristics-mapping of saline alkaline soils-soil erosion and sedimentation-assessment of soil erosion – estimation of reservoir capacity.

UNIT III LAND EVALUATION AND MANAGEMENT

Introduction- land use/land cover definition- land use/ land cover classification-concepts and approaches of land evaluation–Change dynamics–Land capability assessments-decision support system for land use planning -optimum land use planning for sustainable agriculture

UNIT IV DAMAGE ASSESSMENT

Introduction-damage by pests and diseases-crop loss assessment by floods -flood hazard zone mapping-remote sensing capabilities and contributions for drought managementlanddegradationduetowaterloggingandsalinity-cropstress-reflectance properties of stressed cropsidentification of crop stress –Agricultural insurance in India –CCIS,ECIS,FIIS and NAIS

UNIT V FOREST MANAGEMENT
