Turuta // 2019 IEEE 8th International Conference on Advanced Optoelectronics and Lasers (CAOL*2019) : сonference proceedings, Sozopol, Bulgaria, 6-8 September 2019. – P. 553–556.https://openarchive.nure.ua/handle/document/22625In the paper, we present the 3D filtering method of surface approximation based on FT-smoothing proposed to estimate glacier thickness change. Our method based on ICESat/GLAS Altimetry Data and SRTM-DEM Data. Processed data of satellite measurements at the coordinate surface usually placed sparsely, collected in “Satellite track”. For interpolation, we are using 2D membership function. This approach is kind of a generalization of the single-dimension method. The result provides estimated by RMSE, we have managed a number of fuzzy components for improving RMSE.enF-transformSRTM datasetGLASfuzzy transform methodsConference proceedings
