Embodiment Construction
[0038] Such as figure 1 A remote sensing image mapping process shown includes the following steps:
[0039] Step 1. Data source acquisition: acquire remote sensing image data of the measured area, and input the acquired remote sensing image data to the data processor; the remote sensing image data is satellite remote sensing image data or aerial photogrammetry image data.
[0040] In this embodiment, the satellite remote sensing image data and the aerial photogrammetry image data are remote sensing image data obtained by using synthetic aperture radar (SAR) or interferometric synthetic aperture radar (INSAR) to perform remote sensing measurement on the measured area. Using synthetic aperture radar SAR or interferometric synthetic aperture radar INSAR measurement can directly obtain terrain elevation information.
[0041] Step 2. Field photo control measurement: measure the multiple photo control points arranged in the measured area respectively, and obtain photo control measu...
