White-napped cranes migratory roads tracking and surface condition change monitoring by satellite and weather data

Traditionally in China the ring mark method is used for bird migratory road tracking average ten percentages of ring marks can be found after migratory. Any changes of wetland in migratory road or stopover can cause living problems for the birds. The migratory road correspondingly to the economy and population fast developing area of east part of China so that the result of the study can provide scientific information for bird protection and sustainable development of the region. In recent years, Institute of Remote Sensing Applications, CAS, Hokkaido Institute of Environment and the University of Tokyo organized a research project to study migratory roads and monitoring surface condition change using satellite tracking data (NOAA/NNT), NOAA/NDVI, surface temperature data, wetland change GIS data. Some results are introduced in this article
