Digital Elevation Model (DEM) with its rich geometric and topologic information is a black box for the Earth and Planetary scientists to model and visualize terrestrial and planetary surficial processes. Geoscientists with appropriate mathematical knowledge can better exploit the full potential of the DEM that has hitherto been underutilized. More details can be seen at: DEM an Important Source of Data for Geoscientists, IEEE Geoscience and Remote Sensing Magazine, v. 8, no. 4, p. 138-142. 10.1109/MGRS.2020.3031910.
Mathematical Morphology is an area of geoscience that most people don’t realize will literally change the way they look at
Earth and Planetary surfaces! This talk would provide a glimpse of how mathematical morphology could be employed to treat DEMs to derive scientific outcomes.
The speaker :
B. S. Daya Sagar is a Professor (and Founding Head) of the Systems Science and Informatics Unit (SSIU) at the Indian Statistical Institute. Sagar has made significant contributions to the field of geosciences, with special emphasis on the development of spatial algorithms meant for geo-pattern retrieval, analysis, reasoning, modeling, and visualization by using concepts of mathematical morphology and fractal geometry. He has published over 85 papers in journals and has authored and/or guest-edited 11 books and/or special theme issues for journals.
