Comparison and Evaluation of Matching Algorithms Based on Vector Graph Merging
Spatial data matching is an important means of updating geospatial databases. With the accumulation of matching algorithms and matching models,the comprehensive quality evaluation of matching results has become a new research direction. A matching algo-rithm evaluation method based on the vector building merging operator is proposed. Four existing matching algorithms are selected to process two groups of data at the same scale from different sources. The original matching results are compared with the matching re-sults after adding the merging operator. The influence of the merging operator on the matching algorithm is analyzed,and the matching algorithm is compared and evaluated according to the influence of the merging operator. It provides reference for optimal selection of matching algorithms and improvement of matching efficiency for building merging at multiple scales.
