Because the elevation data we have acquired through gps is too variable to satisfy the mapping accuracy requirement the elevation value is solved by the water lever observation in the hydrology station and datum horizon correction of sounding observation
由於gps的rtk模式測量所獲取的高程精度不能滿足測圖精度要求，因此其高程值是通過測量水深值、結合其統一到基準面的改正數、根據相關水文部門各水位站提供的水位觀測資料綜合計算獲得。 -
According to the hong kong observatory s tidal records at the tai po kau tide gauge station, the highest sea level was 2. 94 metres above chart datum on that day
根據香港天文臺大埔?測潮站的記錄，當日的最高水位為海圖基準面以上2 . 94米。 -
( 4 ) finally, the dissertation utilize the observation datum of weather station and prior harvest to validate the result. the results indicate that the computation methods and models based on remote sensing have large practical value
（ 4 ）最後，利用氣象臺站實測資料對反演的結果進行了驗證，結果表明了遙感反演方法及模型具有較大的實際應用價值。 -
As a separate system, the system of statistics and analysis for the reliability of low - voltage user records reliability datum of every low - voltage user by gathering terminals, collects and deals with these datum with the technique of low - voltage power line carrier by lumped instrument. last, the datum in the lumped instrument are read in the database of the master station computer by telephone network
低壓用戶可靠性統計與分析系統作為獨立系統，以低壓臺區為單位，通過採集終端記錄每個低壓用戶的可靠性數據，再採用低壓載波由集中裝置對這些數據進行集中並處理，主站計算機以電話網路撥號的方式將集中器中的數據讀入數據庫。 -
During conversion, the conversion models determined by datum transformation and errors from the gps computation by incorrect coordinates of the reference station under wgs - 84 datum will surely have influence on datum transformation
進行坐標轉換時，由基準轉換確定的轉換模型和參考站不是wgs - 84基準下的正確坐標所致的gps計算誤差，必將對基準轉換產生影響。
