【摘要】：針對測繪成果中入庫數(shù)據(jù)道路實體連通性檢測方面的問題,基于FME平臺設(shè)計開發(fā)了一種道路實體連通性檢測算法。該算法充分考慮了重復(fù)路段的情形,既適用于單線形結(jié)構(gòu)的常規(guī)道路實體,也適用于三岔路結(jié)構(gòu)的非常規(guī)道路實體,并且實現(xiàn)了對各種不同類型道路實體不連通錯誤的精細化檢測。利用模擬數(shù)據(jù)和地理國情普查成果數(shù)據(jù)驗證了算法的正確性與魯棒性。所提算法為入庫道路數(shù)據(jù)的連通性質(zhì)量檢查與修改提供了有力的工具,為數(shù)據(jù)庫建設(shè)中道路數(shù)據(jù)的實體化編碼和網(wǎng)絡(luò)構(gòu)建等數(shù)據(jù)深加工處理奠定了堅實的基礎(chǔ)。
[Abstract]:A road entity connectivity detection algorithm based on FME platform is designed and developed to solve the problem of road entity connectivity detection of database data in surveying and mapping.The algorithm fully considers the case of repeated road sections, which is suitable for both the conventional road entities with a single linear structure and the unconventional road entities with a bifurcated road structure.It also realizes fine detection of disconnected errors of different types of road entities.The correctness and robustness of the algorithm are verified by using the simulated data and the data obtained from the GIS census.The proposed algorithm provides a powerful tool for the quality check and modification of road data connectivity in database construction, and lays a solid foundation for the further processing of road data in database construction, such as the materialized coding of road data and network construction.
