Satellite remote sensing data is an important part of the Geographic Information System database. Using it as the basic data source, Data Interpretation marks are created based on its attribute information to extract basic geographic information data. If we further analyze and study other information related to satellite remote

Images with a spatial resolution of less than 1 MB can accurately reflect the detailed information on the surface of collapsed houses. These images are the main data sources for obtaining information on collapsed houses after disasters and play an important role in disaster reduction and relief. Manual visual interpretation and change detection are the main methods for extracting collapsed houses through high-score images. However, the implementation efficiency of this method is difficult to me
We know that the classification of remote sensing is uncertain, and its uncertainty is closely related to the evaluation method chosen. This paper mainly introduces four aspects, firstly introduces the development of the classification accuracy evaluation of remote sensing, and then introduces the evaluation method of
Python uses OpenCV library for simple meteorological remote sensing image computing.
The full name of OpenCV is Open Source Computer Vision Library, which is a cross-platform Computer Vision Library. OpenCV is a product launched and developed by Intel. It is issued with BSD license and can be used free of charge in the commercial and research fields. OpenCV can be used to develop real-time image processing,
