map collection

The system has realized many functions, such as, the game area environment parameters setting, real-time remote collection of dynamic data, dynamic and real time display of sailing sailboat's state on electronic map ( including velocity, direction and position of a sailing sailboat), etc.

该系统主要实现了赛场环境参数的设置，动态数据的远距离实时采集，训练帆船运行状态（速度、方向、位置）在电子地图上的动态实时显示等功能。

On this basis, this dissertation designs the software system which consists of the data-processing module, the central processing module and the functional modules, and realizes GPS positioning data collection and storage, map matching, operation matching and alarm functions theoretically.

在此基础上，设计了主要由数据处理模块、中央处理模块和功能模块组成的软件系统，并在理论上实现了GPS定位数据的采集、存储，地图匹配，作业计划匹配和告警等功能。

It emphatically introduces how to change the graph by information collection continuous transformation and quantitative transformation in order to obtain a new map, which will make a more thorough analysis of land use.

着重介绍了怎样通过信息提取、连续变换、数量变换等方法改变地图图形，获取新的图件，使土地利用状况的分析更加深透。

A Map is simply a collection of key-value pairings.

一个Map实际上就是键-值对的集合。

In order to making full use of existing information, cutting down high spending on data collection, GIS departments often need to incorporate map data which from various sources, and then Map Conflation appears. And feature matching is the key component of Map Conflation.

为了充分利用已有信息，减少数据采集的高额开销，GIS应用部门经常需要将这些不同来源的地图数据合并在一起使用，这就产生了地图合并技术，而实体匹配是地图合并的关键组成部分。
