Current regional surveying and mapping methods mainly use high-altitude satellite remote sensing images,assisted by manual information collection,resulting in low efficiency and accuracy of surveying and mapping methods,requiring repeated correction.In order to optimize the above analysis defects,the mapping method of land expropriation area for water conservancy project construction based on aerial remote sensing technology will be studied.Set the technical parameters of aerial remote sensing to ensure the accuracy of remote sensing image acquisition.After geometric correction of remote sensing image,image enhancement,denoising and target detection are carried out.The structure of compensating fuzzy neural network is designed,and the mapping information of aerial remote sensing image is extracted by compensating fuzzy neural network.An example is given to verify that the accuracy of remote sensing image information extraction can reach 97.04%by using the proposed mapping method,and the mapping efficiency is obviously improved.
