In this process, surveying and mapping engineering technology has played a very important role. However, there are still some problems and shortcomings in the actual use of surveying and mapping engineering technology. Surveying and mapping technicians should pay more attention to and understand the problems, so as to formulate scientific and effective solutions and further improve the reliability of surveying and mapping engineering technology. This paper mainly analyzes and studies the technical problems of surveying and mapping engineering and puts forward specific improvement measures, so as to provide useful reference and help for relevant personnel.展开更多

In the face of strong external pressure, the surveying and mapping industry needs to do is how to grasp the opportunity of reform, improve their own ability level. In the surveying and mapping management system, there are still some surveying and mapping personnel's operation ability is insufficient, but must be put into work. Surveying and mapping engineering will appear some quality problems. In the context of the information age, the surveying and mapping industry needs to make full use of the advantages of information technology and constantly improve its management efficiency, so as to promote the surveying and mapping industry to occupy a place in the fierce market competition. In this paper, the application of lidar technology in engineering mapping is studied and analyzed for reference.展开更多

In China, land management and utilization are closely related to people's life. The most commonly used method in land management is surveying and mapping technology. The emergence of Surveying and mapping technology not only improves the quality of land management, but also makes rational use of land resources in China. Through the analysis of the relevant technology in surveying and mapping engineering, this paper deeply understands the application of Surveying and Mapping Engineering in land management and utilization, hoping to provide some help to the future land managers.展开更多

A decentralizedmodel predictive control framework is formulated to predict the optimal velocity profile that compromises fuel economy andmobility while guaranteeing the safety of each vehicle. In the model predictive control framework, an engine-map-based fuelconsumption model is established by implementing a backward conventional vehicle model in the cost function. Moreover,the cost function is normalized by dividing each term by its reference value. An extra cost is added to the safety term when thedistance between adjacent vehicles drops to a critical value to guarantee vehicle safety, while another extra cost is consideredfor the velocity tracking term to prevent the violation of traffic rules. The results of simulation show the effectiveness of theproposed control method.展开更多
