模块通常是一个包含函数和类的Python文件。一系列模块支持ArcPy,包括: 数据访问模块(arcpy.da) 制图模块(arcpy.mapping) ArcGIS Spatial Analyst扩展模块() ArcGIS Network Analyst扩展模块() 3. 导入第三方模块 import arcpy import os import sys
因此使用了with’语句后,就不需要在使用del语句。 3.在Python中使用SQL 在地理处理中,经常需要使用结构化查询语言(SQL)查询数据。ArcMap里的按属性选择功能就需要使用SQL,ArcToolBox里面的很多工具也需要用到SQL。 在Python中使用SearchCursor函数可以执行SQL查询语句。SearchCursor的语法如下: SearchCursor(in_table, fie...

For example, if you type “Combine the tables of two inputs” into the Geoprocessing pane’s search bar, you will receive relevant results such as Join Field, Merge, or Append. An example of the top three search results returned from a query that used semantic search. Semantic search is ...

Join data from a Google Sheets cloud-stored spreadsheet table with a feature layer stored in your local file GDB. SQL works all the time with all data sources. Server Side + Client Side - Combine local SQL with native, server side SQL in the same query: For example, run server-side ...
Join Schedule Data and Polygons Now that we have our schedule data in .csv and a polygon layer wrapping around all features for each schedule activity, they can be joined. In this case I am using the Join Field tool in ArcGIS Pro to add the schedule fields to the polygon layer and pop...
