Clip GEDI Level1B data by Coordinates
This function clips GEDI Level1B data (geolocated waveforms) within a given bounding coordinates
clipLevel1B(level1b, xmin, xmax, ymin, ymax, output)
level1b |
A GEDI Level1B object (output of |
xmin |
Numeric. West longitude (x) coordinate of the bounding rectangle, in decimal degrees. |
xmax |
Numeric. East longitude (x) coordinate of the bounding rectangle, in decimal degrees. |
ymin |
Numeric. South latitude (y) coordinate of the bounding rectangle, in decimal degrees. |
ymax |
Numeric. North latitude (y) coordinate of the bounding rectangle, in decimal degrees. |
output |
Optional character path where to save the new hdf5file. The default stores a temporary file only. |
Returns a list of S4 objects of class "gedi.level1b" containing clipped GEDI Level1B data.
