| Abstract: | The efficient detection of mathematical accuracy of digital topographic maps has always been one of the core problems faced by technical quality inspectors in surveying and mapping industry.In order to reduce the laborious detection work and improve the detection efficiency and quality,through the study of FME software and the analysis of accuracy detection processes of topographic map,a mathematical accuracy detection method of digital topographic map based on FME is proposed,the key technology of detection quality evaluation is discussed,and the template of three precision detection of digital topographic map is compiled.The test results show that the mathematical accuracy detection of topographic map can be completed efficiently and non destructively by using FME Workbench.Compared with the traditional human-computer interaction detection method and program software detection method,this method has the characteristics of flexibility,easy operation and high efficiency. |
