基于GIS组件的航迹标绘系统设计与实现

摘要

试验用飞行航迹设计完成后通常需要将各航路点和航段标绘在信息丰富的地图中，用于对航迹是否采用或修改与否进行决策并备案留存。手工标绘一条飞行航迹，耗时一般为15—20min；基于GIS组件的航迹标绘系统，在VC环境下采用DTIS_MAPX组件，数据接口基于XML技术实现，首次将部队手工标绘改进为程序自动读取数据，标绘飞行航迹，并生成配套图例，成功实现了4s标绘一条航迹，操作简便高效，提升了部队信息化作战保障能力．%After finishing the design of trial flight - path, we need to plot the air route point and leg information on a map with abundant information for the purpose of putting the flight - path on record and deciding whether to adopt or improve it. It usually takes 15 to 20 minutes plotting a flight - path manually. Flight - Path Plotting System, which is based on GIS Component, applies DTIS_MAPX component in VC environment anti implements data interface on the basis of XML technique,improves the conventional manual flight - path plotting operation in the armed forces by reading data automatically to plot the flight - path and generate assorted legends. With Flight - Path Plotting System, it is possible to plot a flight - path within 4 seconds and promote the information war supporting capacity of armed forces.
