C1. Based on the linear data association table, all point data with points belonging to lines in the point type data are screened out for verification. If the verification fails, a prompt is output; the point attributes of the point type data include line belonging attributes. For example, point JQ503 belongs to line BILDA-09A. If the verification finds that point JQ503 is not on line BILDA-09A, the verification fails and a prompt is output (if the verification finds that point JQ503 is on line BILDA-09A, the verification passes, and there is no prompt to continue to the next step of verification).

C2. Based on the association table of linear data, all point data with points belonging to a surface in the point type data are screened out for verification. If the verification fails, a prompt is output; the point attributes of the point type data include surface belonging attributes. For example, a point belongs to the ICAOCode (information area code) surface. If the verification finds that the point is not on the ICAOCode (information area code) surface, the verification fails and a prompt is output (if the verification finds that the point is on the ICAOCode (information area code) surface, the verification passes, and there is no prompt to continue the next step of verification).

C3. Based on the linear data association table, all line data with lines belonging to surfaces in the line type data are screened out for verification. If the verification fails, a prompt is output.

C4. Check whether all lines in the line type data and the surface type data that contain the attribute of non-intersection exist. If the check fails, output a prompt.

C5. Set point terrain attributes in the point attributes of each type of data in the point type data of civil aviation navigation data and check all points separately. The point terrain attributes are the verification rules for whether the point data can intersect with the three-dimensional terrain. If the verification fails, a prompt is output. For example, waypoints and terrain data cannot intersect. During data verification, if there is an intersection between waypoints and terrain data, the verification fails, indicating that there is a problem with the data; navigation station points, runway endpoints and three-dimensional terrain must intersect. If a navigation station point (a hardware device) or a runway endpoint should be above the terrain surface (that is, there is no intersection), the verification fails.

C6. Set the line terrain attribute in the line attribute of each type of data in the line type data of civil aviation navigation data and check all lines separately. The line terrain attribute is the verification rule for whether the line data can intersect with the three-dimensional terrain. If the verification fails, a prompt is output. For example, the route data is line data, and the route data cannot intersect with the terrain data. If the route data (a type of line data) intersects with the terrain data, the verification fails, indicating that there is a problem with the encoding, because the lines are all flight trajectories and cannot cross the terrain.

C7. Set the surface terrain attributes in the surface attributes of each type of data in the surface type data of civil aviation navigation data and check all surfaces separately. The surface terrain attributes are the verification rules for whether the surface data can intersect with the three-dimensional terrain. If the verification fails, a prompt is output. The surface type data is slightly special. The surface type data is a surface on the plane, and it is a cylinder in three-dimensional space. This cylinder has a lower height limit, an upper height limit, or only an upper limit without a lower limit. Take the control area surface as an example. If it is an airway control area, it cannot intersect with the terrain. If it is a terminal area control, there is no lower limit expression, then there can be an intersection. For example, if it is an information area surface, the terrain data intersection check is not performed because the information area surface is a surface without upper and lower height limits.

After data fusion and graphical verification, this embodiment can produce civil aviation navigation data within this AIRAC cycle. The civil aviation navigation data produced by this embodiment can easily calculate the distance between point data and point data; when producing navigation data, some points are not named on the aeronautical chart, and the airborne equipment needs a point for navigation. In this case, a new point needs to be introduced. Then the accuracy and reliability of this point cannot be checked based on the aeronautical chart, because the exact latitude and longitude information of this point is not given on the chart. Then when introducing this point, there is a specific naming specification, the direction distance naming method, the first letter is D, the 2nd to 4th characters are the angle, and the last character represents the distance, that is, with a distance of 1 nautical mile as the interval, represented by A, B, C...; for example, the point named D185J represents 185 degrees and 10 nautical miles. After calculating the direction and distance of this point, it can be verified whether the encoding is correct.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
