Prof. Gerrid de Leeuw, FMI, Finland.
Prof. Ronald van der, KNMI, The Netherlands.
1st special session's summary
Environmental pollution become more and more serious due to today’s development all around the world. Air pollution is one of the most important environmental problems, which concentrates mostly in cities. Air pollution has long been a problem in the industrial nations of the West. It has now become an increasing source of environmental degradation in the developing nations of Africa. Remote sensing has been widely used for environmental application such as for air quality and water quality studies. Earth observation satellites have developed with much higher spatial and spectral resolutions, and the data transmission speed and storage capacity are increasing accordingly. The amount of remote sensing data produced by airborne and spaceborne sensors is increasing at a rate of a terabyte per day, and a single data set can reach a gigabyte.
Although atmospheric remote sensing data can help estimate air pollution levels, these data have limitations especially if used on their own. Big Earth Data provides a new vision and methodology to Earth sciences. Big Earth Data is about using various different types of spatial geo-data and developing relevant tools within the overall context of a computational scientific approach. It is concerned with new computational techniques, algorithms, and paradigms to enhance the air quality monitoring that are dependent upon and can take advantage of Big Earth Data. This Special Session will offer presentations from a variety of sources, both local, national and international and will enable you to network with others working in similar fields.

2nd special session's title:

« Dynamic monitoring of regional resource and environment by high resolution remote sensing data »

2nd special session's conveners:
Prof. Bing Zhang, Institute of Remote Sensing and Digital Earth, Chinese Academy of Sciences, China.
2nd special session's summary
The session is related with the remotely sensed monitoring in aspects such as natural resource, energy, ecological environment, natural disaster by using the high resolution remote sensing data. It is especially focused on the dynamic changes of reginal area around the world. The preferred topics are the followings, but not limited to the methodologies, technologies, and new findings over hot-spots area revealed by multi-source series of high resolution remote sensing data.
