Resourcesat-1 data quality evaluation system

Evaluation and use of Resourcesat-I data for agricultural applications

Resourcesat-1 satellite offers a unique opportunity of simultaneous observations at three different spatial scales through LISSIV, LISS-III (improved LISS-III) and AWiFS sensors from a common platform. The sensors have enhanced capabilities in terms of spectral, spatial and radiometric resolution as compared to earlier Indian Remote sensing Satellite sensors. This paper summarizes the results o...

Geometric Quality Assessment of Vhr Satellite Imagery with Ortho-rectified Cartosat-1 Data – a Case Study

Data products from satellite instruments with moderate to high spatial resolution are assessed for their geometric accuracy with the help of topographic maps or geo-coded satellite imagery generally at 1:50,000 scale. With advancement in high precision attitude and orbital control systems onboard, considerable attention has been paid in the recent past to improve methods for better accurate ass...

Meeting Earth Observation Requirements for Global Agricultural Monitoring: An Evaluation of the Revisit Capabilities of Current and Planned Moderate Resolution Optical Earth Observing Missions

Agriculture is a highly dynamic process in space and time, with many applications requiring data with both a relatively high temporal resolution (at least every 8 days) and fine-to-moderate (FTM < 100 m) spatial resolution. The relatively infrequent revisit of FTM optical satellite observatories coupled with the impacts of cloud occultation have translated into a barrier for the derivation of a...

Complementarity of ResourceSat-1 AWiFS and Landsat TM/ETM+ sensors

Evaluation of performance quality of SPECT camera in Shariati Hospital of Tehran University of Medical Sciences [Persian]

In nuclear medicine, there are two methods of imaging, planar and tomography. Single photon emission computerized tomography (SPECT) shows better image details and therefore is influenced more by image parameters such as resolution, uniformity, sensitivity, etc. Manufacturers provide customers with data which are obtained by complicated and sometimes secret methods. Marketing companies te...
