Analysis of INSAT 3A CCD NDVI data for crop monitoring in rabi season
Over the last 30 years, coarse resolution satellite sensors are being used routinely to monitor crops and other vegetation, to generate various estimates on their areal extent and to detect the impact of moisture stress on vegetation, at regional scales. Satellite derived Vegetation indices have been used extensively for varied geospatial applications in agriculture. Vegetation indices show better sensitivity than individual band reflectance and hence are more preferred for crop vigor assessment, crop discrimination, crop monitoring etc. Vegetation indices also act as proxies to various crop bio-physical parameters. NDVI, the most popular index due to its simplicity in computation and interpretation has been found to be a proven index for crop studies. As a result, several geospatial products of NDVI and its derivatives are available as free downloads from various sensors of moderate to coarse resolutions. But all these datasets are from polar orbiting satellite systems and are limited by inadequate temporal repitivity, leading to the presence of considerable extent of cloud infestation in the composite images. Geostationary satellites with constant viewing direction produce the images of higher geometric fidelity and their very high temporal frequency reduce the residual cloud content in the composite images.
Application potential of geostationary satellite data for crop monitoring is investigated in the current study. Indian Geostationary satellite INSAT 3A launched in 2003 provides spectral data in red, NIR and SWIR bands at 1km spatial resolution through its CCD sensor. It has a very high temporal receptivity (half an hour) with constant view direction.NDVI generated at multiple times in a day from INSAT provide opportunity to get more cloud free NDVI compared polar orbiting large swath satellites (Fensholtet al., 2006).
