| Abstract: | Due to the rapid changes of the urban construction, it is necessary to apply the technology of aerial photograph remote sensing to the information system for urban earthquake disaster prevention and reduction. Using the technology of aerial photograph remote sensing, the information system for urban earthquake disaster prevention and reduction can obtain information directly from scanning image of aerial photograph and build various types of character database in shorter time. In this paper, the selection and application of aerial photograph, the technology of electronic vectorization for scanning image of aerial photograph, the corresponding investigation of data, and the new probing into database maintenance of the system are introduced. |
