Report: IGARSS 2012

IGARSS 2012 (International Geoscience and Remote Sensing

Symposium) was held from July 22 to 27 in Munich, under the auspices of IEEE(*1) GRSS(*2). IEEE GRSS is one of 38 societies establishedin 1962, celebrating its 50th anniversary this year. IGARSS is one of

the biggest conferences related to remote sensing and it is 29th now.
There were more than 3,200 presentations found in the abstract,which were seen in 16 different places, and also there were many
