Hi, Although not using RGB for all rasters and a neutral grey for feature classes, I was able to solve my symbology issue.                     desc = arcpy.Describe(data)                      mxd_new = arcpy.mapping.MapDocument(mxd_out)                      df = arcpy.mapping.ListDataFrames(mxd_new, '*')[0]                      try:                              lyrFile = arcpy.mapping.Layer(data)                              if desc.dataType == 'RasterDataset':                                 layerType = arcpy.management.MakeRasterLayer                                  result = layerType(lyrFile, 'temp_layer')                                 layer_object = result.getOutput(0)                                 arcpy.mapping.AddLayer(df, layer_object)                              else:                                 result = arcpy.management.MakeFeatureLayer(lyrFile, 'temp_layer')                                 layer_object = result.getOutput(0)                                 arcpy.mapping.AddLayer(df, layer_object) This is the key to changing the symbology and adding it to the dataframe before exporting to thumbnail format.

Hi All, Ended up only needing one line of code to capture my error files as suggested. try:                             val = desc.SpatialReference.name                                                      except: Whole code to perform my error checking: import arcpy, sys, traceback, os from arcpy import env  env.workspace = <your workspace>  log = r'D:\Temp\error.log'  contents = []  print 'Starting'  if arcpy.Exists(log):                           arcpy.Delete_management(log)                            for dirpath, dirnames, datatypes in arcpy.da.Walk(env.workspace):         contents.append(os.path.join(dirpath))  for item in contents:     if arcpy.Exists(item):                      arcpy.env.workspace = item         featureType = ['Coverage', 'Raster', 'Feature']         for type in featureType:                 datasetList = arcpy.ListDatasets("*", type)                 for dataset in datasetList:                          data = item + "\\" + dataset                          desc = arcpy.Describe(data)                         print data + ' : ' + desc.dataType                                                  try:                             val = desc.SpatialReference.name                                                      except:                             arcpy.ExecuteError                             arcpy.AddError(arcpy.GetMessage(2))                             f=open(log, 'at')                             f.write(data + '\n')                             f.close()  ##                            tb = sys.exc_info()[2] ##                            tbinfo = traceback.format_tb(tb)[0] ##                            f=open(log, 'at') ##                            f.write(data + '\n') ##                            f.close()  print 'Done' Trying to describe the spatial reference would cause an error on corrupted files allowing them to be recorded for checking. Tried using 'continue' but didn't seem to work, so leaving it out, the script runs regardless. I was experimenting with ExecuteError and Traceback. Both will work. (OS Windows 7, ArcGIS 10.1 SP1).

Code is working nicely that Arek supplied, but I think I need to clarify a bit more. Column1 / Column3 1000 : PlaceA 1000 : PlaceA 1005 : PlaceA 1005 : PlaceA 1009 : PlaceB 1009 : PlaceB After running the dictionary code I found similar named places in Column 3 but with different codes in Column 1. This was something I wasn't aware of until now. I will need to distinguish between same name using different codes. I could not get the original definition query code to work: 'fldCode in (%s)' % map_dict[str(fldName)].join(', ') so substituted with: queryStr = "\"" + fldCode + "\" = " + str(row[1]) My complete code follows, but needs further work to achieve my desired output. import arcpy  fc = r"D:\Locations.gdb\Places" fldName = "Place_Name" # Column 3 = row[0] fldCode = "Place_Code" # Column 1 = row[1]  map_dict = {}  with arcpy.da.SearchCursor(fc, (fldName, fldCode)) as collector:     uniqueValues = sorted(set(collector))     if not row[0] in map_dict.keys():       map_dict[row[0]] = []     if not row[1] in map_dict[row[0]]:       map_dict[row[0]].append(row[1])      queryStr = "\"" + fldCode + "\" = " + str(row[1])      mxd = arcpy.mapping.MapDocument(r"D:\Places.mxd")      elm = arcpy.mapping.ListLayoutElements(mxd, "TEXT_ELEMENT")[0]     elm.text = "Place: " + row[0]      df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0]      for lyr in arcpy.mapping.ListLayers(mxd, "", df):              if lyr.name == "Places":                  if lyr.supports("DEFINITIONQUERY"):                     lyr.definitionQuery = queryStr      arcpy.RefreshActiveView()      arcpy.mapping.ExportToPDF(mxd, r"D:\Places\Output" + "\\" + row[0] + "_" + row[1] + ".pdf")   del mxd I am trying to make map outputs that will only show places based on their unique code values. I think I may have what I need now, but will notify forum if issues remaining. Will investigate dictionaries further. Regards, Craig ... View more

Hi All, Ended up making my own simple symbol to orientate people facing signage placed in different positions with different orientations. Was hoping something already existed and may have been a standard or widely utilised. Simple overhead depiction of a head (circle) in front of signage (rectangular box). Circle and rectangle will be incorporated into a style and rotated according to signage placements. [ATTACH=CONFIG]22197[/ATTACH] Regards, Craig ... View more
