Embodiment Construction
[0050] In this embodiment, the attached figure 2 The remote sensing image shown is used as the initial image for the identification of coastal ocean features and landforms. The remote sensing image data was taken by the TM theme imager of Landsat 5 satellite on January 2, 2007. The image size of the embodiment area is 500×500 pixels, and the area is located in the Xinying Bay Mangrove Nature Reserve in the northwest of Hainan Island. The specific implementation of this example adopts the standard C++ programming language to realize under the VC 6.0 platform, and the reading and writing operation of the remote sensing image data is realized through the open-source geographic data format conversion class library GDAL 1.60. The specific implementation steps are as follows:
[0051] Step 1: Use GDAL as the image data reading and writing tool, and use the GDAL.Open method to read remote sensing images. According to the marine and coastal characteristics of Hainan Island, the gro...
