I'm trying to advise a non-gis user about which application offers more options. I've done some studies of both apps and think that Explorer offers more menu options, like querying. However, ArcGIS.com is newer. Is ArcGis.com meant to replace Explorer online?  I'd really appreciate any comments or opinions about which app offers more options. Ken ... View more

I looked thru the esri sample code and determined that the "replaceDatasource" function may fix broken links. However, I need to modify the script to fix broken links in many mxds. I hoping someone can spot the problem in this script: import arcpy, os, glob mxds_path = r'S:\\Users Shared\\LOpperman\\Town Scale MXDs\\MXDs\\targetlayers\\' layer_name = r'dams' data_frame = r'Primary'  for infile in glob.glob(os.path.join( mxds_path, "*.mxd" )):          mxd = arcpy.mapping.MapDocument(infile)           for df in arcpy.mapping.ListDataFrames(mxd, data_frame):              for lyr in arcpy.mapping.ListLayers(mxd, "", df):                lyr.replaceDataSource("dams")       mxd.save() ...

I'm frustrated that the ESRI sample scripts do not allow updating multiple mxds. In the real world why would someone go to the trouble to modify a sample script that just updates one mxd?  Would it not just be faster to make the change to the single mxd?  Every scenrio I encounter requires updating a huge no of mxds. Here's a script  that works, on our server, to remove multiple layers from multiple mxds. Could someone, please, tell me how to mod it to update layer. I tried modifying the sample layer available from esri and couldn't even get close. I just want to change the color symbology of the dams layer, for all of the mxds stored in the target layers folder, with the source layer, Dams, archived in an "update layers" folder on my server Ken import arcpy import os import glob mxds_path = r'S:\\Users Shared\\LOpperman\\Town Scale MXDs\\MXDs\\targetlayers\\' layer_name = r'dams' data_frame = r'Primary' layers = [] mxds = [] for infile in glob.glob(os.path.join( mxds_path, "*.mxd" )):   mxd = arcpy.mapping.MapDocument(infile)   print "removing Dams layer from "  + infile   for df in arcpy.mapping.ListDataFrames(mxd, data_frame):     for lyr in arcpy.mapping.ListLayers(mxd, "", df):       #print lyr       if lyr.name.lower() == layer_name:         print 'Remove layer ' + layer_name         arcpy.mapping.RemoveLayer(df, lyr)   #copyFile = mxds_path + r"NEW_" +   #print copyFile   mxd.save()   #for mxd_name in mxds:   #mxd = arcpy.mapping.MapDocument(mxds_path + mxd_name)   #print 'removing layer for ' + mxd_name   #  mxd.save()  [/COD] ...

I attempted to modify a sample code to remove just one layer from one of the two data frames, "Primary", I have in multiple mxds, all stored in the same folder.  This code runs, but does not actually remove the layer, "Dams", from the two text mxds, stored in the folder, RemoveLayers1.  I've specified upper, considering Dams starts with a cap D, but maybe it requires a diff command when caps are mixed with lower case. I'm hoping someone can see what I'm missing. I would expect the code to provide an error message; not just fail to remove the layer. import arcpy import os import glob mxds_path = r'C:\\Temp\\removelayers1\\' layer_name = r'Dams' data_frame = r'Primary' layers = [] mxds = []   for infile in glob.glob(os.path.join( mxds_path, "*.mxd" )):   mxd = arcpy.mapping.MapDocument(infile)   print "removing Dams layer from "  + infile   for df in arcpy.mapping.ListDataFrames(mxd, data_frame):     for lyr in arcpy.mapping.ListLayers(mxd, "", df):       #print lyr       if lyr.name.upper() == layer_name:         print 'Remove layer ' + layer_name         arcpy.mapping.RemoveLayer(df, lyr)         #for mxd_name in mxds:   #mxd = arcpy.mapping.MapDocument(mxds_path + mxd_name)   #print 'removing layer for ' + mxd_name    #  mxd.save() Ken ...
