鴻蒙開發學習【地圖位置服務組件】

簡介

移動終端設備已經深入人們日常生活的方方面面,如查看所在城市的天氣、新聞軼事、出行打車、旅行導航、運動記錄。這些習以為常的活動,都離不開定位用戶終端設備的位置。

當用戶處于這些豐富的使用場景中時,系統的位置定位能力可以提供實時準確的位置數據。對于開發者,設計基于位置體驗的服務,也可以更好的滿足用戶的需求。

當應用在實現基于設備位置的功能時,如:駕車導航,記錄運動軌跡等,可以調用該模塊的API接口,完成位置信息的獲取

基本概念

位置能力用于確定用戶設備在哪里,系統使用位置坐標標示用戶設備的位置,并使用多種定位技術提供位置服務,如GNSS定位、基站定位、WLAN/藍牙定位(基站定位、WLAN/藍牙定位后續統稱“網絡定位技術”)。通過這些定位技術,無論用戶設備在室內或是戶外,都可以準確地確定用戶設備的位置。

  • 坐標
    系統以1984年世界大地坐標系統為參考,使用經度、緯度數據描述地球上的一個位置。
  • GNSS定位
    基于全球導航衛星系統,包含:GPS、GLONASS、北斗、Galileo等,通過導航衛星,設備芯片提供的定位算法,來確定設備準確位置。定位過程具體使用哪些定位系統,取決于用戶設備的硬件能力。
  • 基站定位
    根據設備當前駐網基站和相鄰基站的位置,估算設備當前位置。此定位方式的定位結果精度相對較低,并且需要設備可以訪問蜂窩網絡。
  • WLAN、藍牙定位
    根據設備可搜索到的周圍WLAN、藍牙設備位置,估算設備當前位置。此定位方式的定位結果精度依賴設備周圍可見的固定WLAN、藍牙設備的分布,密度較高時,精度也相較與基站定位方式更高,同時也需要設備可以訪問網絡。

約束

  • 使用設備的位置能力,需要用戶進行確認并主動開啟位置開關。如果位置開關沒有開啟,系統不會向任何應用提供位置服務。
  • 設備位置信息屬于用戶敏感數據,所以即使用戶已經開啟位置開關,應用在獲取設備位置前仍需向用戶申請位置訪問權限。在用戶確認允許后,系統才會向應用提供位置服務。
