Applications of IRS1C/1D Satellite Images - Part II

The advantage of repetitive Wifs data with poor spatial resolution is to estimate products. The analysis of Wifs data at different times indicates the phenological changes that cause the product to be isolated and can be used to identify the products and changes due to different stages of growth.The results of the Wifs data at different times show that different products are separated according to temporal and spectral characteristics. However, they show similar shapes like forest, city and deep water with their little or no changes. These shapes can be used to normalize atmospheric effects on temporal data needed for spectral profiles.
