The recognition of various types of water bodies on satellite image
卫星图像中不同水体类型识别研究

The data of satellite remote sensing can provide real time information of the earth's surface accurately. Now the commercial satellites can provide the satellite images with the resolution between 10 meter and 1 meter. With those high spatial resolution images, shape features and texture features of the ground objects including large buildings of city, roads, rivers, lakes and other man made objects are very clear. With the characters of the high resolution satellite image, we will use the recognition of the type of water bodies as an example, begin with the extraction of the spectrum features of the ground objects from the satellite digital images, separate water bodies from background and recognize it through the classification of the image, implement the recombination of the pixels, then extract and describe the shape features of water bodies and implement the recognition of various water bodies on the partition of areas and the tracing of boundary. The experiments of the recognition of various types of water bodies on the satellite image prove this recognizing method is feasible with high spatial resolution satellite images.
