利用arcgis提取點(diǎn)屬性的方法步驟

1、利用arcgis提取采樣點(diǎn)插值數(shù)據(jù)的方法第一部分：利用已知點(diǎn)數(shù)據(jù)插值生成raster圖層1、把excel表格數(shù)據(jù)導(dǎo)入到arcgis中（注意要導(dǎo)入 excel數(shù)據(jù)的經(jīng)度、維度分別用表示，否則會(huì)出現(xiàn)問題）碧輯 區(qū)字體23456789101112131415A 河乃泰 *巴木海勒 詈吉福阿蘊(yùn)、一雖克瑪山子湖 河彖臺 石蔡奇T2047.116787. 466712L 900047.7333類，0833191,300046. 983389. 5167189.6000 |1146.7333關(guān),0000282. 400046. 783385. 7167136. 300046. 666790. 3833170
