arcgis自定义缓冲区工具箱python代码

以下是一个可以生成自定义缓冲区的ArcGIS Python工具箱代码示例：

import arcpy

class CustomBufferTool(object):
    def __init__(self):
        self.label = "Custom Buffer Tool"
        self.description = "Creates a buffer of user-specified distance and units."
        self.canRunInBackground = False

    def getParameterInfo(self):
        # Define parameters
        params = []
        
        # Input feature class parameter
        in_fc = arcpy.Parameter(
            displayName="Input Feature Class",
            name="input_fc",
            datatype="GPFeatureLayer",
            parameterType="Required",
            direction="Input")
        params.append(in_fc)

        # Output feature class parameter
        out_fc = arcpy.Parameter(
            displayName="Output Feature Class",
            name="output_fc",
            datatype="DEFeatureClass",
            parameterType="Required",
            direction="Output")
        params.append(out_fc)

        # Distance parameter
        distance = arcpy.Parameter(
            displayName="Distance",
            name="distance",
            datatype="GPLong",
            parameterType="Required",
            direction="Input")
        params.append(distance)

        # Distance units parameter
        units = arcpy.Parameter(
            displayName="Units",
            name="units",
            datatype="GPString",
            parameterType="Required",
            direction="Input")
        units.filter.type = "ValueList"
        units.filter.list = ["Meters", "Kilometers", "Feet", "Miles"]
        params.append(units)

        return params

    def execute(self, parameters, messages):
        # Get input parameters
        in_fc = parameters[0].valueAsText
        out_fc = parameters[1].valueAsText
        distance = parameters[2].value
        units = parameters[3].value

        # Create buffer
        buffer_distance = "{} {}".format(distance, units)
        arcpy.Buffer_analysis(in_fc, out_fc, buffer_distance)

        # Print success message
        messages.addMessage("Custom buffer created successfully.")

        return

要使用此代码，请将其保存为.py文件，然后在ArcGIS中将其添加到工具箱中。在添加工具时，指定输入和输出参数以及距离和单位参数。执行工具后，将创建一个自定义缓冲区。
