鴻蒙開發(fā)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(tǒng)的位置定位能力可以提供實時準確的位置數(shù)據。對于開發(fā)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(xiàn)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(tǒng)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(xù)統(tǒng)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(tǒng)以1984年世界大地坐標系統(tǒng)為參考，使用經度、緯度數(shù)據描述地球上的一個位置。 - GNSS定位
基于全球導航衛(wèi)星系統(tǒng)，包含：GPS、GLONASS、北斗、Galileo等，通過導航衛(wèi)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(tǒng)，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(tǒng)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(shù)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(tǒng)才會向應用提供位置服務。
