Navigation Electronic Map Data Production Platform Upgrade Project Evaluation

Navigation electronic map data is the foundation of navigation application. With the increasing popularity of the navigation application, the market for navigation electronic map data precision demand is higher and higher, also by the previous extensive navigation navigation application gradually evolved to realize precise guidance from door to door. At the same time, the domestic market of navigation through in recent years, the rapid development of the form and application of navigation products are changed, the contents of the navigation electronic map data richness, and the pedestrian navigation function,3d imaging navigation function, door site navigation function index of interest points, multimedia, and other functions support the needs of the increasingly urgent. In addition, the rapid development of the domestic infrastructure construction and the acceleration of urbanization construction, to improve the navigation electronic map update frequency, shorten the production period of navigation electronic maps, guarantee the navigation electronic map data processing.along demand is particularly urgent.The development of society and the progress of science and technology in the navigation electronic map data is put forward higher requirements of the above at the same time, and for the production of navigation electronic map data provides a rich source of information, such as:aerospace photogrammetry achievement, the urban basic surveying and mapping results and so on.To meet the market demands for navigation products all kinds of new, keep product innovation level and in line with international standards, the project is based on the navigation electronic map, make full use of multi-source map change information, the introduction of a series of new technologies, new elements, improve the precision of navigation electronic map data, broaden the scope of application of navigation electronic map’s, produce high processing.along, multi-purpose precision navigation electronic map products.This article first to the project evaluation and project management related theory research results summarized. Then, in this paper, the necessity and feasibility of the project implementation in detail, finally to the project put forward constructive views. To effectively evaluate results.
