The sections above provide the theoretical background behind geometry in general. While using the ArcGIS API for Python, we primarily work with well-known IDs called as wkid. For instance, the wkid of Web Mercator PCS explained above is 3857. Occasionally, you might see a latestWkid being use...
Geometry Engines The Python API uses either shapely or arcpy as back-ends (engines) for processing geometries. The API is identical no matter which you use. However, at any point in time, only one engine will be used. The section below shows you how to access your geometries as their cor...
ArcGIS API for Python是一个功能强大,现代且易于使用的Pythonic库,用于执行GIS可视化和分析,空间数据管理和GIS系统管理任务,这些任务既可以交互运行,也可以使用脚本运行。 ArcGIS API for Python分别使用ArcGIS Online和ArcGIS Enterprise提供的在线和本地Web GIS平台实现。API具有用于管理和使用ArcGIS平台信息模型元素的Pyth...

方法一:通过Python的pandas和geopandas处理 如果你需要在arcpy的环境下安装库,推荐用conda安装环境,避免库之间的冲突,出现错误了也能够回滚环境。 geopandas通过运行conda install geopandas -c esri来安装。 1.读取excel文件 importpandasaspddf=pd.read_excel("./resource/data2/中国第七次人口普查-分年龄_性别的人...
