利用arcpy实现ArcGIS的split,erase,intersext和union代码实现功能

以下是利用arcpy实现ArcGIS的split,erase,intersext和union的代码实现功能的示例：

1. Split

import arcpy

# 输入要素类路径
in_features = "C:/data/input.gdb/input_fc"

# 拆分要素类的字段
split_field = "Split_Field"

# 拆分后的输出要素类路径
out_feature_class = "C:/data/output.gdb/split_fc"

# 使用 Split 工具进行拆分
arcpy.Split_analysis(in_features, out_feature_class, split_field)

2. Erase

import arcpy

# 输入要素类路径
in_features = "C:/data/input.gdb/input_fc"

# 要擦除的要素类路径
erase_features = "C:/data/input.gdb/erase_fc"

# 擦除后的输出要素类路径
out_feature_class = "C:/data/output.gdb/erase_fc"

# 使用 Erase 工具进行擦除
arcpy.Erase_analysis(in_features, erase_features, out_feature_class)

3. Intersect

import arcpy

# 输入要素类路径
in_features = "C:/data/input.gdb/input_fc"

# 相交的要素类路径
intersect_features = "C:/data/input.gdb/intersect_fc"

# 相交后的输出要素类路径
out_feature_class = "C:/data/output.gdb/intersect_fc"

# 使用 Intersect 工具进行相交
arcpy.Intersect_analysis([in_features, intersect_features], out_feature_class)

4. Union

import arcpy

# 输入要素类路径
in_features = "C:/data/input.gdb/input_fc"

# 要合并的要素类路径
union_features = "C:/data/input.gdb/union_fc"

# 合并后的输出要素类路径
out_feature_class = "C:/data/output.gdb/union_fc"

# 使用 Union 工具进行合并
arcpy.Union_analysis([in_features, union_features], out_feature_class)
