Abstract

The invention discloses an OSGi (Open Service Gateway Initiative) based MODIS data distributed processing method. The OSGi based MODIS data distributed processing method comprises the steps of carrying out parallelization and componentization transformation for an MODIS data production algorithm which is realized by programming an IDL language so as to enable the transformed algorithm to be dynamically deployed and installed in the distributed OSGi environment; producing and packaging the MODIS data into standard service in OSGi; and realizing distributed production of the MODIS through service calling. According to the OSGi based MODIS data distributed processing method, computing resources in the local area network are integrated, the efficiency of MODIS data processing is increased, the production mode of man-machine operation of original software is changed, manual interaction and error probability in a data production process are reduced, and a uniform and standard management mode is brought to the MODIS data production.

Description

technical field [0001] The invention belongs to the technical field of remote sensing image processing, and mainly relates to an OSGi-based MODIS data distributed processing method. Background technique [0002] In recent years, population growth and economic development have put great pressure on my country's water environment. Droughts occur frequently, and have the characteristics of high frequency, long duration, and large impact range, which has become the biggest problem facing my country's agricultural production. . The traditional drought monitoring method is to use the measured data of national meteorological stations to weight and interpolate to obtain the distribution of drought in the whole country. This method cannot guarantee the accuracy and integrity of the obtained results. With the development of remote sensing technology and the increase of remote sensing means, its large-scale, continuous and uninterrupted characteristics make real-time dynamic monitoring...
