method of producing a digital map of geographical positions approach road

摘要

method of production of digital geographic map positions by smoothing process route based on route thousands of position (latitude, longitude) without the need of satellite image.the data collection system was designed and developed in-house, it is to integrate gps last generation microcontroller programmed to take control of the precise location and provide an integrated computer programmed to collect data born gps, and stored in the file. it is mounted on a vehicle.we can make as many routes as possible without difficulty and without the need for special supervision, these routes are made on all the roads in the area. the set of files is shown in the gis software to show all the positions.the profiles of all other roads in the area are we then to reproduce boundary smoothing the arteries. by approximation and field study, we can have all the other features. the result is marked on the ground. all the data is rich in the area. the product is tested on the ground and then validated
