Welcome to the Earthdata User Forum! Here, subject matter experts from several NASA Distributed Active Archive Centers (DAAC) can discuss general questions, research needs and data applications. Users can query how to access, view and interpret the data.
User Submitted Question: There are not single Lat/Long locations for every single return in the waveform, right? The waveform product is like a distribution function of elevations / canopy height within a 25 m footprint?
That is correct, there are not single lat/lon locations for every single value represented in each waveform. Rather, for every GEDI shot, there are lat/lon locations representing the start of the RX window (latitude/longitude_bin0) and the end of the RX window (latitude/longitude_lastbin). In the Getting Started with GEDI L1B Data in Python Jupyter Notebook tutorial, we use the latitude/longitude_bin0 values to define the location of the GEDI shot, and the elevation_bin0 (elevation of the start of the RX window) and elevation_lastbin (elevation at the end of the RX window) to interpolate the 3-d location of each waveform value for that shot.
