This session addressed areas beyond the traditional forestry, agriculture
and sea ice applications for polarimetric SAR. Recommendations called for:
1) research in surface scattering properties; 2) development of fully-polarimetric
systems with short temporal repeat capabilities; 3) development of biomass
quantification capabilities (forestry and agriculture); 4) research in
urban classification based on texture and 5) easy access to dual- and fully-polarimetric
products for decision makers.
1) Session Topics
a) Natural Hazards Mapping
i) L-Band (and perhaps C- and P-Band) entropy and alpha parameters
can be used for classification of disasters that remove vegetation from
the surface (change scattering from surface to volume scattering).
ii) POLSAR should be used operationally for landslide, volcanic eruption,
wildfire and flood identification.
iii) Airborne and Unmanned Autonomous Vehicle (UAV) systems should
be developed for quick response to disasters.
iv) Explore the usability of POLinSAR for biomass disruption mapping
and recovery monitoring.
b) Precision Farming and Crop Management
i) C- , L and X-band dual-polarimetry may be used for agricultural
ii) Develop satellite systems with repeat time of 3-5 days and commercial
applications for farmers.
iii) Demonstrate the fusion of POLSAR data with optical data.
c) Urban Mapping
Identify and map urban density and land use with POLSAR.
d) Oil Slick Detection and Identification
Circular polarization coherence and anisotropy can be used to locate
oil slicks, estimate thickness and identify texture of the oil layer. Develop
capability to use this method operationally and research the scattering
properties of oil slicks.
2) Other Topics (from roundtable discussion)
a) Currently, difInSAR is used to detect surface deformation. POLinSAR
can be implemented to address the change in polarimetric properties between
two interferometric scenes. This technique may be useful for measuring
b) Wetlands may be studied with the use of long wavelength POLinSAR
to monitor the depth of the vadose (unsaturated zone). Applications in
this area may be similar to flood and rice crop management.
c) Terrestrial glaciers should be studied to see how their volume scattering
and roughness properties relate to those of sea ice.
d) Aerial platforms have the unique capability to monitor areas with
a high repeat time (hours) and on short notice. UAVs have the added benefit
of keeping the data collector(s) out of harms way. We need to explore this
option for areas of human (i.e. oil slicks) and natural (i.e. landslide,
e) Tornadoes also change surface scattering properties and their trails
can be detected using POLSAR.
