Embodiment Construction
[0042] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0043] refer to figure 1 , this example uses multi-source remote sensing data to analyze the mitigation effect of wetland landscape on the heat island effect. The specific steps are as follows:
[0044] S1. Select a 5*5 landscape area on the Landsat8 image as a macro level group. The resolution of the Landsat8 image is smaller than the image data acquired by the QuickBird satellite described below, and the two form two high-resolution and low-resolution image data.
[0045] S2. Use the QuickBird satellite to obtain the high-score images corresponding to the above-mentioned landscape areas, each pixel on the high-score image data, and use the high-score classification map of the landscape area to calculate the landscape...
