Multisource Fusion for Multidimensional Analysis
Multisource Fusion
• Combine multiple images into composite
products
=>bring out more information than that
of individual input images
• More applications demand the use of
multiple data modalities
• Integration of Radar, Lidar, Optical,
Hyperspectral, Stereo, Thermal and
more is driving how applications
consume and process data
• These modalities will be combined to
create an even richer geospatial
context for decision making

Map to Fine Wine
Vineyards in Napa Valley are producing
better wine and refining their growth and
harvesting processes with the help of data
processing and imagery produced with
ENVI.
Susan Mahler and Paul Skinner of Terra
Spase, located in Napa, California are using
airborne remote sensing data, in
combination with soil sample analyses, to
help vintners improve irrigation and nutrition
management, make crop adjustments, and
monitor disease and pest populations. At
harvest time, the imagery enables vintners
to plan harvesting strategies for reaping fruit
at a similar and proper level of maturity.
