尝试循环多个空间范围以创建4个不同图层的17个联合。arcgis union python error
我正在运行ArcGIS Desktop 10.0，ArcInfo（高级）。
Gridnums = range(1,18)
for i in Gridnums:
#vis6class = ws + "/" + "TVvis6class_G" + str(i)
inList = arcpy.ListFeatureClasses("*ProcGrid_"+str(i), "")
print "inList: " + str(inList)
arcpy.Union_analysis([InList], ws + "/" + "TVvis6class_G" + str(i))
print "Union completed for Grid " + str(i)
arcpy.AddField_management(vis6class, "Object", "TEXT", 10)
arcpy.AddField_management(vis6class, "Revert", "SHORT")
rows = arcpy.UpdateCursor(vis6class)
for row in rows:
row.Revert = 0
if row.Road == 1:
row.Object = Road
rows.updateRow(row)
elif row.Water == 1:
row.Object = Water
rows.updateRow(row)
elif row.Building == 1:
row.Object = Building
rows.updateRow(row)
else:
row.Object = row.Landcover
rows.updateRow(row)
错误代码（不是非常有帮助）：
inList: [u'Road_ProcGrid_1', u'FPs_S_ProcGrid_1', u'er_di_ProcGrid_1', u'TV_v_ProcGrid_1']
Traceback (most recent call last): File "E:\Projects\TV\01_Python\LandCover\LC_2_Vector_Tile_6class_091312.py", line 48, in arcpy.Union_analysis([InList], ws + "/" + "TVvis6class_G" + str(i)) File "C:\Program Files\ArcGIS\Desktop10.0\arcpy\arcpy\analysis.py", line 483, in Union raise e RuntimeError: Object: Error in executing tool
我知道这是编程论坛在ArcGIS中，但我已经张贴到ESRI论坛以及，有很多的意见，但很少反馈。 工具本身运行，如果我手动选择每个数据集的特定程度，所以问题必须在编码。
感谢您的任何想法。
