Description

technical field

[0001] The invention belongs to the field of computer-aided design, and specifically refers to a visual and instrument flight program automation aided design system. Background technique

[0002] At present, domestic flight procedure aided design systems include: flight procedure design based on GIS, flight procedure computer aided design system (FPCAD for short) of Civil Aviation North China Air Traffic Management Bureau, and auxiliary flight procedure design system based on MAPINFO or SUPERMAP as the development platform. In 1996, the North China Bureau developed FPCAD, namely "Non-Precision Approach Computer Aided System", and there is no mature product yet. The assisted flight procedure design system based on MAPINFO or SUPERMAP as the development platform is an early product of GIS. The domestically developed flight procedure assisted design methods and systems are all based on scanned maps, and there is a problem of map splicing. Moreover, these aided ...

Examples

Embodiment approach

[0042] Step 1: The user inputs the latitude and longitude grid parameters: coordinate system type (WG84 / Beijing 54 / Xi'an 80 / CGCS2000), the latitude and longitude of the center point, the upper and lower limits of the latitude and longitude grid, and the degree interval of latitude and longitude.

[0043] Step 2: The system automatically calculates the longitude and latitude coordinate set P of the point sets at fixed intervals on the central meridian and all longitude and latitude lines.

[0044] Step 3: The system automatically converts the point set latitude and longitude coordinate set P into the geometric coordinate set G on the CAD screen interface.

[0045] Step 4: The system draws the central meridian and all longitude and latitude lines on the screen according to the geometric coordinate set G.

[0046] 2. Implementation of the geographic coordinate system query and export sub-module:

[0047] Step 1: The user clicks the coordinate system export button;
