The area of a polygon feature. The area is zero for all other feature types. Double centroid (読み取り専用) The true centroid if it is within or on the feature; otherwise, it is the label point. Point extent (読み書き) The extent of the geometry. ...
You can also change the drawing order when the layer contains features that overlap or cover each other. For example, if you adjust the drawing order of the area field of a polygon feature layer, you can ensure that smaller polygons draw on top of larger polygons. ...
我们在这里使用Reclassify命令进行打分分类,对坡度,距离道路距离,日照强度进行分类,统一度量衡为1-5,然后使用Weighted Overlay进行加权叠加运算,最后使用Reclassify功能选取4-5范围区间并使用Raster to Polygon进行格式转化,得到APPRO_Build.shp作...
Calculate the percentage area of each classified area of the slope map. Open the attribute table of the polygon layer. Right-click the new field created in Step 3, and clickCalculate Field. TheCalculate Fieldwindow opens. ForInput Table, select the polygon layer. In this example, the polygon...

添加了两个字段:Summarized Area in SQUAREKILOMETERS和Count of Polygons,前者表示每个地区的水库总面积(以平方千米为单位),后者表示每个区域范围内的水库数量。 注: 了解如何更改新字段的别名,尝试学习此教程管理包含过多字段的图层。 关闭属性表和地理处理窗格。
该文件夹中包含稍后您将在课程中使用的 3 个数据文件:一个图层包:ConstructionArea.lpkx以及两个场景图层包:GrandCentral_V1.slpk和GrandCentral_V2.slpk。 接下来,您将在 ArcGIS Pro 中创建一个全球场景。 4.启动 ArcGIS Pro。如果收到系统提示,请使用您获得许可的 ArcGIS 组织帐户登录。
In ArcGIS Pro, the width of a polygon can be calculated to gauge the map size accurately. This is helpful to print a portrait layout of the map with width limitations. Calculating the accurate width o
在ArcToolbox工具箱选择Conversion—>From Raster—>Raster to Polygon工具,输入栅格数据Watershed_1,字段选择Value,输出矢量面域数据RasterToPolygon_1。 5.10 提取汇流量小于10 km2 小流域 在菜单栏中选择Selection—>Select By Attributes工具,在Layer中选择RasterToPology_1,输入Shape_Area<=10000000,点击OK进行筛选。
在执行洪水分析之前,您需要确保在ArcGIS Pro工程中具有正确的环境设置和适合您需求的数据。 您将从两个栅格开始,将它们合并为一个栅格,填充栅格数据中的空白,将栅格裁剪到研究区域,然后将高程单位从米转换为厘米。 下载数据 首先,您将下载ArcGIS Pro工程包并熟悉在本教程中使用的数据。
