Abstract

The invention provides a spatial data edge matching detection method and device, and is applied to the field of data processing. The spatial data edge matching detection method comprises the following steps: carrying out edge matching detection on a first spatial data set and a second spatial data set which are to be subjected to the edge matching detection, and constructing a buffer region serving as an edge matching graph selection geometry through an edge matching line between the two spatial data sets; and acquiring whether a first edge matching graph and a second edge matching graph are in graph edge matching through a preset graph edge matching judgment method, then judging whether the attribute values of two elements complementary for graph edge matching are equal, and judging the two edge matching graphs which are complementary for the graph edge matching and have the equal attribute values to be spatial data edge matching. The applied spatial data edge matching judgment method is not limited by the fact whether the states of the graph elements in the spatial data sets are standard, and can carry out edge matching judgment on any spatial data sets with irregular states, so that the general applicability, the detection accuracy and the efficiency of the spatial data edge matching judgment method are improved to an extremely large extent.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method and a device for detecting spatial data borders. Background technique [0002] Edge quality is one of the important evaluation indicators of data quality, and it is also an important content of the quality inspection of geographic national conditions census data. Vector data is one of the main data formats of geographic national conditions census results, and its data organization has two methods: standard map sheet and administrative division. Due to the large amount of vector data organized by administrative divisions, the efficiency of manual inspection is extremely low and it is easy to miss. Therefore, it is necessary to study an automatic inspection method to ensure the quality of national census data and improve the efficiency of data acceptance. [0003] Edge quality is an important index to evaluate the quality of vector data. , most of the existing research is ...
