摘要:
Landsat Thematic Mapper data are utilized to improve upon the ground yield survey estimates for wheat in India. The normalized difference and ratio vegetation indices computed from the spectral responses are used to obtain homogeneous vegetation vigour stratifications of the cropland of the study area. Certain post-stratified estimators that make use of these stratifications are investigated and are shown to provide improved crop yield estimates.
