Prior to being able to use an image in a landuse classification exercise one must first make fundamental corrections to the image data. the level of corrections differs for each satellite sensor but will generally involve sensor calibration for radiometric correction ( sun angles, earth - sun distances and atmospheric scattering effects ), geometric corrections and geo - referencing to a known coordinate system
在將圖像用於土地利用分類處理之前，必須首先對圖像資料進行基本修正。對于不同的衛星感測器需採用不同的修正參數和方法，但一般涉及感測器校正，包括輻射校正（太陽角度角、地球與太陽的距離和大氣層的散射效應） 、幾何校正以及設制地理座標。 -
Yield - measurement is a key technology of desiderating resolution in precision agriculture system. it is necessary in our country that studying the methods of grain - flow - measurement in lab. many methods of measuring grain flow on combines are presented in the literature, such as volumetric method, impact sensor, radiometric method and capacitor sensor, etc
因此，穀物流量實時在線測量方法作為當前「精細農業」體系中的基礎環節及亟待解決的關鍵技術之一，在我國嘗試性地在實驗室中進行多種方案的并行探索是十分必要的。 -
