NASA Develops CASALS to Improve Earth's 3D Mapping

• NASA's Goddard Space Flight Center developed the CASALS instrument.
• CASALS uses machine learning to blend lidar data and fill gaps in Earth's surface maps.
• The instrument is supported by NASA's Earth Science Technology Office.
• CASALS will help researchers map Earth's features in greater detail.
• Current space-based laser instruments measure Earth's surface in narrow lines, leaving large gaps unmeasured.
