Question

我正在尝试编写一个python脚本来处理图像文件到shapefile，然后用5米缓冲区缓冲这些文件。我首先在arcmap中的模型构建器中创建了脚本，但我试图为多个图像文件运行它，所有这些都以字母LG开头。我一直收到错误00865，声明输入栅格（图像文件）不存在!!我已经检查了一百万次文件夹，它确实存在！这是我的代码：

# Import system modules
import sys, string, os, arcgisscripting

# Create the Geoprocessor object
gp = arcgisscripting.create()

# Load required toolboxes...
gp.AddToolbox("C:/Program Files/ArcGIS/ArcToolbox/Toolboxes/Conversion Tools.tbx")
gp.AddToolbox("C:/Program Files/ArcGIS/ArcToolbox/Toolboxes/Analysis Tools.tbx")

# Script arguments...

folder = "D:\\J04-0083\\IMAGEFILES"
for root, dirs, filenames in os.walk(folder): # returms root, dirs, and files
    for filename in filenames:
        filename_split = os.path.splitext(filename) # filename and extensionname (extension in [1])
        filename_zero = filename_split[0]

        try:
            first_2_letters = filename_zero[0] + filename_zero[1]
        except:
            first_2_letters = "XX"

        if first_2_letters == "LG":
            Output_polygon_features = "D:\\J04-0083\\ShapeFiles.gdb\\" + "SH_" + filename + ".shp"

            # Process: Raster to Polygon...

            InRaster = filename_zero + ".png"
            gp.RasterToPolygon_conversion(InRaster, Output_polygon_features, "SIMPLIFY", "VALUE") # FILL IN THE CORRECT VALUES!

            Distance__value_or_field_ = "5 Meters"
            Raster_Buffer_shp = "D:\\J04-0083\\ShapeFiles.gdb\\" + "SB_" + filename + ".shp"
            # Process: Buffer...
            gp.Buffer_analysis(Output_polygon_features, Raster_Buffer_shp, Distance__value_or_field_, "FULL", "ROUND", "NONE", "")

有谁知道为什么它不起作用？谢谢！

我不知道你在哪里运行脚本，但是当你打电话给gp.RasterToPolygon_conversion时，你只给它文件 name ，而不是完整路径。如果文件不在工作目录中，则无法找到它。尝试替换该行：

InRaster = filename_zero + ".png"

使用：

InRaster = os.path.join(root, filename_zero + ".png")

错误00865！ ArcMap地理处理。光栅到多边形
