Paper Abstract

The Japan Aerospace Exploration Agency (JAXA) has started a conceptual study of earth observation missions with a space-borne laser scanner (GLS, as Global Laser Scanner). Laser scanners are systems which transmit intense pulsed laser light to the ground from an airplane or a satellite, receive the scattered light, and measure the distance to the surface from the round-trip delay time of the pulse. With scanning mechanisms, GLS can obtain high-accuracy three-dimensional (3D) information from all over the world.

High-accuracy 3D information is quite useful in various areas. Currently, following applications are considered.

1. Observation of tree heights to estimate the biomass quantity.

2. Making the global elevation map with high resolution.

3. Observation of ice-sheets.

This paper aims at reporting the present state of our conceptual study of the GLS. A prospective performance of the GLS for earth observation missions mentioned above.
