ArcMap行政區(qū)經緯度擬合提取

ArcGis區(qū)域經緯度擬合一、ArcMap導入矢量圖?shp存儲的是幾何要素的的空間信息，也就是XY坐標.shx存儲的是有關*.shp存儲的索引信息。它記錄了在*.shp中，空間數據是如何存儲的，XY坐標的輸入點在哪里，有多少XY坐標對等信息?dbf存儲地理數據的屬性信息的dBase表這三個文件是一個shapefile的基本文件。打開一幅矢量圖，只要打開.shp文件，兩個方法：方法1：點擊adddata,然后選擇.shp文件；方法2：直接將.shp文件拖拽至ArcMap中打開;導入矢量圖后如下圖所示：S<無標題—Arclap-ArcinfoSelection.Selection.FileEditViewBoolmiu-ksInsertGeoprocessingCustomizeWindowsHelp□凸凰卷itiBxgc步“河両—~Hie圉③國鬲口冋曰園訂圃阿廠可|壓硒晶jb題Q針o：：氏斤觀?蒿曲體畀硬三TableOfContents匡]9◎勒圄-^3Layers
