GIS Modeling与Python介绍

ArcGIS中提供了两种写Python的方式：

  • ModelBuilder
  • IDLE

ModelBuilder的使用很简单，可以先拿来做模型的结构设计。 但是一些复杂的处理则需要写Python Script来实现。

因此：

Using Python window in ArcGIS：

import arcpy
arcpy.Buffer_analysis("us_cities", "us_cities_buffered", "15 miles", "", "", "ALL")

注意：所有需要调用ArcGIS的Tools的脚本，都需要import arcpy

比如打印feature的空间参考：

# Opens a feature class from a geodatabase and prints the spatial reference
 
import arcpy
  
featureClass = "C:/Data/USA/USA.gdb/StateBoundaries"
   
# Describe the feature class and get its spatial reference   
desc = arcpy.Describe(featureClass)
spatialRef = desc.spatialReference
    
# Print the spatial reference name
print spatialRef.Name
