Mahapatra, Pravas R and Makkapati, Vishnu V (2005) Performance Enhancement of a Spline-based Method for Extreme Compression of Weather Radar Reflectivity Data. In: Fifth IEEE International Symposium on Signal Processing and Information Technology. ISSPIT 2005, 18-21 December, Athens,Greece, pp. 147-152.
Enhancements are carried out to a contour-based method for extreme compression of weather radar reflectivity data for efficient storage and transmission over low-bandwidth data links. In particular, a new method of systematically adjusting the control points to obtain better reconstruction of the contours using B-Spline interpolation is presented. Further, bit-level manipulations to achieve higher compression ratios are investigated. The efficacy of these enhancements is quantitatively evaluated with respect to achievable compression ratios and the root-mean-square error of the retrieved contours, and qualitatively assessed from the visual fidelity of the reconstructed contours. Results are presented for actual Doppler weather radar data sets.
