Remote Sensing and Gis Application in Crop Mapping

Description

For irrigation water resources management and planning, cropping pattern is an important input. During project planning, project cropping pattern is proposed and based on this irrigation water demand are estimated. This demand, along with other demand for water supply, hydropower, industry, recreation etc. is used to compute total water demand for the project. Utilization of irrigation potential increases post dam construction as progress in irrigation infrastructure development occurs. Thus, area under irrigation increases over time. Apart from this increasing trend, fluctuations in irrigated area occur due to variability in water availability in the project. Conventionally, crop and irrigated area statistics are collected at village level. Remote sensing provides an alternate method for crop and irrigated area monitoring. In India, there is high spatial and temporal variability in agriculture land cover, mainly due to fragmented and small land holding. This leads to variability in crop type, rotation and their sowing dates etc. in turn posing challenges in their delineation using remote sensing. Various methods used in monitoring of crops and irrigated area are discussed in this book “Remote Sensing and GIS Application in Crop Mapping”. This book addresses many critical aspects, such as, crop area estimation, crop yield & production etc.
