| Abstract: | Data from the Advanced Very High Resolution Radiometer (AVHRR) on board the NOAA–10 satellite was collected over Indiana for the 1987 and 1988 growing seasons. A Normalized Difference (NDVI) transformation was applied to the data. Over 45 fields representing 8 soil associations were sampled to assess the effects of the 1988 drought on the development of natural and cultivated vegetation. The results show the effect of the lack of available moisture to the plants and its effect on the response measured by the AVHRR sensor. |
