Problems solved by technology

With the construction of the digital twin city, a series of practical problems have been exposed, such as the low efficiency of urban spatial data processing, the variety of urban spatial basic data, and the large amount of data. It is far from meeting the current needs if purely relying on manual processing
[0003] In the process of digital twin city basic data construction and warehousing, it is necessary to perform quality inspection on all spatial data, among which data field attribute inspection is essential, but now it can only be interpreted and inspected manually, which greatly affects efficiency. Since there are also errors in manual interpretation, there is an urgent need for a method that can automatically check and process spatial data in this area

Embodiment 1

[0039] The present invention is applied to the spatial data layer field inspection method of the digital twin city. Based on ArcGIS, the field of each layer of spatial data is checked according to the type, and the wrong field is output. The method includes the following steps:

[0040] S100. Set a configuration file, the configuration file includes a check form, and the check form is used to fill in field information to be checked;

[0041] S200. According to the classification, respectively set the data source of the spatial data, and obtain various types of spatial data;

[0042] S300. Taking the field recorded in the configuration file as the target field, and taking the field to be checked in the spatial data as the source field, perform batch inspection processing on various types of spatial data based on ArcGIS and through the check items set in the configuration file. If the target field is the same as the source field If they do not match, record the field, mark the l...

Embodiment 2

[0082] The present invention is applied to a digital twin city spatial data layer field checking system, including a configuration file generating module, a data source module and a checking module, the configuration file generating module is used to set a configuration file, the configuration file includes a checking table, and the checking The form is used to fill in the field information to be checked; the data module is used to set the data source of the spatial data according to the classification, and obtain various types of spatial data; the check module is used to use the fields recorded in the configuration file as the target The field to be checked is the source field. Based on ArcGIS and the check items set by the configuration file, various types of spatial data are checked in batches. If the target field does not match the source field, the field is recorded and the layer is identified. Into the created error identification file, so as to select and correct the lay...

Abstract

The invention discloses a spatial data layer field inspection method and system applied to a digital twin city, belongs to the technical field of digital twin data processing, and aims to solve the technical problem of how to automatically inspect and process spatial data of the digital twin city. Comprising the following steps: setting a configuration file which comprises a check table used for filling field information to be checked; according to the classification, respectively setting data sources of the spatial data, and obtaining various spatial data; taking a field recorded in the configuration file as a target field, taking a to-be-checked field of the spatial data as a source field, performing batch checking processing on various spatial data through checking items set by the configuration file based on ArcGIS, if the target field is not matched with the source field, recording the field, identifying a layer, and if the target field is not matched with the source field, recording the field and identifying the layer; and storing the spatial data into the created error identification file so as to select and correct the layer elements which are subjected to annotation verification to obtain errors, and carrying out attribute assignment on the spatial data which are verified to be correct.
