TL;DR: In this paper, a multi-temporal ERS-1 SAR data acquired over a large agricultural region in West Bengal was used to classify kharif crops like rice, jute and sugarcane.
Abstract: Multi‐temporal ERS‐1 SAR data acquired over a large agricultural region in West Bengal was used to classify kharif crops like rice, jute and sugarcane. Rice crop grown under lowland management practice showed a temporal characteristic. The dynamic range of backscatter was highest for this crop in temporal SAR data. This was used to classify rice using temporal SAR data. Such temporal character was not observed for the other study crops, which may be due to the difference in cultivation practice and crop calendar. Significant increase in backscatter from the ploughed fields was used to derive information on onset and duration of land preparations. Synergistic use of optical remote sensing data and SAR data increased the separability of rice crop from homesteads and permanent vegetation classes.

TL;DR: Two spatial distributed models based on one-dimensional (1-D) energy balance equation to assess land surface damage caused by a storm surge are described.
Abstract: This paper describes two spatial distributed models based on one-dimensional (1-D) energy balance equation to assess land surface damage caused by a storm surge. IRS LISS III and RADARSAT SAR data were used to generate critical model input parameters. The model's performance was validated for the Orissa super cyclone storm surge, India.
