1, development coverage
"Daodaotong" national navigation electronic map products cover all 337 administrative divisions above the prefecture level and 2862 municipal districts and 2860 county-level administrative divisions in 3/kloc-0 provinces, autonomous regions and municipalities directly under the central government, which is more accurate than "isolated island", regardless of cities, towns and villages.
2. Road information
A good map needs comprehensive and real road data collection. For each road, its shape, location, connection relationship, up-down relationship, intersection shape and traffic control information should be accurately collected. And record the road name, width, lane information, pavement material and smoothness in detail. Daodaotong has fully realized this.
Disadvantages of Daodaotong:
1. You can't browse and understand the whole route in remote navigation.
2. When "simulated navigation" is used for long-distance planning (cross-city), the planned route is inconsistent with the actual simulated navigation route, and the detailed information of the planned road is not easy to understand.
3. There are few information points, and many information points have fallen behind other navigation software.
4. The map update speed is slow.
5. The interface brightness of night mode is too bright.
4. There is little road data information in rural areas.
5. The information at the intersection is not obvious. You can't specify the area very specifically.
6. The interface is not practical and the user experience is low.
