500 ## - GENERAL NOTE
General note The Earth is changing continually with changes in the global climate making it imperative to<br/>study these changes. NASA’s Ice Cloud and Land Elevation Satellite-2 (ICESat-2) is a spaceborne LiDAR <br/>system which uses photon-time data to obtain elevations above the Earth. This study uses Multiple Altimeter<br/>Beam Experimental Lidar (MABEL) data which is a model of the Advanced Topographical Laser Altimeter System (ATLAS)<br/>to be incorporated into ICESat-2, to provide the end-user, an efficacious interactive tool to de-noise<br/>the noisy airborne photon data and visualize<br/>it graphically. A three-level de-noising methodology was adapted. In the<br/>first, statistical level, 3σ-elimination was performed. For the second level, line de-noising, all<br/>photons having more than one elevation for the same distance were removed. The last and third<br/>de-noising method is fine denoising, in which a co-ordinate geometry was applied to compute<br/>respective photon densities within an ellipse, was implemented. Elimination of noise photon<br/>was then carried out according to a density threshold. The statistical de-noising removed a few<br/>noisy data but were inconsequential in some cases. The iterative refinement cleared noise step<br/>by step while leaving the actual feature intact. The interface will provide an efficacious way<br/>for the end-user to perform the above-mentioned tasks with a single tool. The main purpose or<br/>advantage of this tool is to remove noise of any complex MABEL data. The de-noised data can<br/>be further used obtain landform features and when done periodically, can be instrumental in<br/>studying changes in the area of interest. There is no such tool to remove noise from MABEL<br/>data. Developing this tool in IDL has a purpose that the most famous geospatial analytics<br/>software like ENVI is written in IDL. So, this tool would be compatible with ENVI.
