6. CONCLUSIONS AND OUTLOOK 
The evaluation of angular signatures from stereo datasets 
provided surprisingly detailed information on land objects. The 
approach is not able to replace the well-known multispectral 
approach completely; the correlation of spectral signatures to 
bio- and geo-physical parameters is higher and at the moment 
better understood. Nevertheless, the approach showed new and 
innovative aspects and seems to be worthy of more intensive 
investigations, such as: 
• the expansion of stereo data use from topographic mapping 
and DEM generation to thematic analysis. This may be of 
importance in thematic processing of panchromatic stereo 
datasets from the next sensor generation like Quick Bird 
(scheduled for 1999), Spot 7 (2002), ALOS (2002), IRS P6, 
etc., which are primarily designed for topographic mapping 
purposes (economic benefit). 
• the introduction of an additional physical parameter in the 
thematic analysis of remote sensing data, which improves 
the accuracy of classification and status assessment 
(scientific/economic benefit). 
• anisotropic backscattering in the optical region and intensity 
of microwave signals are both functions of stand structure 
and plant architecture. The anisotropy approach may 
therefore play a key role in relating bio- and geo-physical 
parameter retrieval from optical and microwave data 
analysis (scientific/economic benefit). 
Our recommendation is to develop the design of MOMS-02 to a 
system, which can acquire simultaneously along-track stereo, 
high resolution and multispectral data.
