ArcGIS教程：创建包含插图的地图册（二）

为导出准备地图文档

    创建范围指示器并记录脚本所需信息之后，设置地图文档，避免每一页上都显示范围指示器或插图。

    步骤:

• 将包含插图的数据框移出页面的可打印范围。
• 将插图的范围更改为比主数据框的范围大很多，使得范围指示器不会出现在不想其出现的页面上。

• 保存地图文档。

编写导出脚本

    下面显示一个示例脚本，该脚本将导出在第 1 页和第 3 页上有插图的地图册。

    下面的脚本将导出在第 1 页和第 3 页上有插图的地图册。

import arcpy, os

# Create an output directory variable

#

outDir = r"C:\Project\MapBook\final_output" 

# Create a new, empty pdf document in the specified output directory

# This will be your final product

finalpdf_filename = outDir + r"\FinalMapBook.pdf"

if os.path.exists(finalpdf_filename): # Check to see if file already exists, delete if it does

  os.remove(finalpdf_filename)

finalPdf = arcpy.mapping.PDFDocumentCreate(finalpdf_filename)

# Create a Data Driven Pages object from the mxd you wish to export

#

# Create objects for the layout elements that will be moving, e.g., inset data frame, scale text

dataFrame = arcpy.mapping.ListDataFrames(tempMap, "Inset Map")[0] 

# Instead of exporting all pages at once, you will need to use a loop to export one at a time 

# This allows you to check each index and execute code to add inset maps to the correct pages

  # If the current page index matches, it will execute code to set up that page

del tempMap

# Update the properties of the final pdf
