Trajectory data refers to the ordered sequences of spatio-temporal positions that describe the path of a moving object over time. It evolves from raw trajectory data, which are directly generated by sensors capturing the position of the object, to structured trajectory data that provide more clarit...
Create a trajectory dataset Trajectory files can be managed and analyzed inArcGIS Proas trajectory datasets and layers. A dataset can be created using theCreate Trajectory Datasettool, which builds a container in a geodatabase to store the footprint geometries, metadata, and references for the tra...
The incredible progress witnessed in geographic information and pervasive systems equipped with positioning technologies have motivated the evolving of classic data towards mobility or trajectory data resulting from moving objects' displacements and activities. Provided trajectory data have to be extracted, ...
【论文精读】轨迹数据应用:Citywide Traffic Volume Estimation Using Trajectory Data 宅家学算法 伪程序员1 人赞同了该文章 本文来源于TRANSACTIONS ON KNOWLEDGE AND DATA ENGINEERING。由于工作需要,开始了解一下轨迹数据的分析思路、应用方向,这篇文章的应用点、可实现性比较恰合我的试验环境,因而认真记录一番。
The advances in location-acquisition and mobile computing techniques have generated massive spatial trajectory data, which represent the mobility of a diversity of moving objects, such as people, vehicles and animals. Many techniques have been proposed for processing, managing and mining trajectory data...

In this chapter, we deal with trajectory database management issues and physical aspects of trajectory database systems, such as indexing and query processing. Our emphasis is on historical databases handling past positions of moving objects represented as trajectories. This is because only such databa...
Remarks:The process of trajectory collection and data transmission is purely anonymous. Specifically, it is not to collect any personal information regarding the vehicles (the vehicle ID has been anonymized as a bit string) as well as the drivers. For the collection of the trajectory dataset, we...
The Data Recording feature is a convenient way to output data about trajectories to the Log window or to a text file (such as for use in other programs).See also Data Import/Export.Exporting “data recording” results to text file The following procedure will cause SIMION “Data Recording”...
论文: Similarity-Based Compression of GPS Trajectory Data 轨迹数据的冗余分为: 轨迹间的冗余:多个轨迹之间的冗余; 轨迹内的冗余:单个轨迹内部上下轨迹点之间的冗余,包括但不仅限于速度、方向、距离; 由于时间上的偏差是影响轨迹间冗余删除的重要因素,目前有两种方式来解决: ...
