ArcMap+ArcPy批量导出油井点PDF

利用 ArcMap 和 ArcPy 批量生成油井点之记并导出 PDF

准备工作

确保安装 ArcMap 10.x 及以上版本，并熟悉 Python 和 ArcPy 基础语法。准备油井点图层（如 Shapefile 或 Feature Class），字段需包含油井名称、坐标、深度等关键信息。

设计 MXD 布局模板

在 ArcMap 中创建布局视图，插入数据框并加载油井点图层。添加动态文本（如油井名称、坐标）和数据驱动页面元素。右键数据框选择 属性 → 数据驱动页面，设置油井点图层为索引图层，确保每页对应一个油井点。

编写 ArcPy 脚本

以下脚本实现批量导出 PDF，假设油井点图层为 well_points，MXD 模板路径为 C:/templates/well_template.mxd：

import arcpy

# 设置工作环境和路径
mxd_path = "C:/templates/well_template.mxd"
output_folder = "C:/output_pdfs"
arcpy.env.overwriteOutput = True

# 加载 MXD 并启用数据驱动页面
mxd = arcpy.mapping.MapDocument(mxd_path)
mxd.dataDrivenPages.refresh()

# 遍历所有页面并导出 PDF
for pageNum in range(1, mxd.dataDrivenPages.pageCount + 1):
    mxd.dataDrivenPages.currentPageID = pageNum
    pageName = mxd.dataDrivenPages.pageRow.getValue("well_name")  # 假设字段名为 well_name
    output_pdf = f"{output_folder}/{pageName}.pdf"
    arcpy.mapping.ExportToPDF(mxd, output_pdf)

# 释放资源
del mxd

关键参数说明

• dataDrivenPages.pageRow.getValue("字段名")：动态获取当前页面对应的油井属性值。
• ExportToPDF：导出时可通过参数调整分辨率（如 resolution=300）和页面大小。

优化与调试

若导出内容偏移，检查布局视图中元素是否锁定。通过 arcpy.mapping.ListLayoutElements(mxd, "TEXT_ELEMENT") 可动态修改文本内容。

结果验证

打开生成的 PDF，确认每页包含对应油井信息。可通过脚本日志或 print 语句输出处理进度。

扩展应用

结合 arcpy.da.SearchCursor 实现条件筛选，仅导出特定油井。添加多线程可加速大批量处理。

此方法适用于标准化制图场景，减少重复操作并提升效率。
