ArcMap行政区经纬度拟合提取

ArcGis区域经纬度拟合一、ArcMap导入矢量图・shp存储的是几何要素的的空间信息，也就是XY坐标.shx存储的是有关*.shp存储的索引信息。它记录了在*.shp中，空间数据是如何存储的，XY坐标的输入点在哪里，有多少XY坐标对等信息・dbf存储地理数据的属性信息的dBase表这三个文件是一个shapefile的基本文件。打开一幅矢量图，只要打开.shp文件，两个方法：方法1：点击adddata,然后选择.shp文件；方法2：直接将.shp文件拖拽至ArcMap中打开;导入矢量图后如下图所示：S<无标题—Arclap-ArcinfoSelection.Selection.FileEditViewBoolmiu-ksInsertGeoprocessingCustomizeWindowsHelp□凸凰卷itiBxgc步“河両—~Hie圉③国鬲口冋曰园訂圃阿厂可|壓硒晶jb題Q針o：：氏斤观®蒿曲體畀硬三TableOfContents匡]9◎勒圄-^3Layers
