And C6, setting line topography attributes in line attributes of each type of data in line type data of the civil aviation navigation data, and respectively checking all lines, wherein the line topography attributes are checking rules of whether the line data can intersect with the three-dimensional topography or not, and if the line data does not pass the checking, outputting prompts. For example, the route and voyage data is line data, the route and voyage data cannot be intersected with the terrain data, if the intersection of the route and voyage data (one type of line data) and the terrain data occurs, the verification is not passed, and the coding is problematic because the lines are all flight tracks and cannot pass through the terrain.
And C7, setting surface topography attributes in the surface attributes of each type of data in the surface type data of the civil aviation navigation data, and respectively checking all surfaces, wherein the surface topography attributes are checking rules of whether the surface data can intersect with the three-dimensional topography, and if the surface topography attributes do not pass the checking, outputting prompts. The face type data is slightly specific, is a face in a plane, and is a cylindrical body in a three-dimensional space, and the cylindrical body has a lower limit of height, an upper limit of height or only has an upper limit without a lower limit. Taking the control area as an example, if the control area is a navigation control area, the control area cannot be intersected with the terrain. If the terminal area control is not expressed by the lower limit, an intersection can be formed, and for example, an information area surface is formed, and the terrain data intersection inspection is not performed because the information area surface is a surface without the upper and lower limits of the height.
After data fusion and graphical verification, the embodiment can produce civil aviation navigation data in the current AIRAC period. The civil aviation navigation data produced by the embodiment can be used for conveniently calculating the distance between the point data and the point data; in the case of navigation data production, some points are not given a name on the map, and the on-board device needs a point for navigation, in which case a new point needs to be introduced. The accuracy and reliability of this point cannot be checked against the chart because the exact latitude and longitude information of this point is not given on the chart. When this point is introduced, there is a specific naming convention, the direction distance nomenclature, the first letter is D, the 2 nd-4 th characters are angles, the last character represents distance, i.e. distance 1 sea is the interval, denoted by A, B, C … …; for example, the point named D185J represents 185 degrees and 10 sea distances, and after calculating the direction and distance of this point, it can be verified whether the code is right or not.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
