Rezatec does not currently use spaceborne LiDAR in our standard Forestry Products. We have evaluated the use of spaceborne LiDAR as an additional data source.  There are currently 3 operational instruments for this type of technology: GaoFen7, GEDI, and IceSAT 2.  While there are a handful of organizations conducting research, we are not aware of any plans for a dedicated (optical) satellite sensor solely for the purpose of digital terrain model extraction.  Furthermore, the Committee on Earth Observation Satellites does not have record of any future or planned spaceborne LiDAR scheduled for development or deployment in the next three years.  There’s also no mention of NASA, ESA, or JAXA having any planned missions or deployment of sensors.
