Sorry there was a typo in the code. The variable above should be hurricaneLayerName. hurricaneLayerName = "Hurricanes" #replace with name of hurricane layer hurricaneLayer = arcpy.mapping.ListLayers(mxd, hurricaneLayerName, df)[0] You were on the right track though. You can just pass in the name, but it needs to be the name of the layer in the map, not the shapefile name (They could be different). You would also need to surrond it in quotes, because it is a string. hurricaneLayer = arcpy.mapping.ListLayers(mxd, "hurr_data", df)[0] ... View more

To accomplish this you are going to need to use python, which you could then create a script tool from and use in model builder. Below is a code sample. Basically we are opening the MXD, gettting some references to the data frame and layers and then stepping through time. At each step we perform our analysis and then move to the next time step. #Get a reference to the map document and first data frame mxd = arcpy.mapping.MapDocument('Current') #If code is run in the app with the MXD open, otherwise pass the path to the MXD df = arcpy.mapping.ListDataFrames(mxd)[0] #Assuming here there is only one data frame in the MXD rasterLayerName = "SST" #replace with name of netCDF raster layer rasterLayer = arcpy.mapping.ListLayers(mxd, rasterLayerName, df)[0] hurricaneLayer = "Hurricanes" #replace with name of hurricane layer hurricaneLayer = arcpy.mapping.ListLayers(mxd, hurricaneLayerName, df)[0] #Loop through each time step within the full time extent df.time.currentTime = df.time.startTime while df.time.currentTime <= df.time.endTime:     #Add your logic here, I assume you are using extract values to point     #So we don't overwrite the output each time, we need a unique name, this will append the Year and Month value currently being processed.     uniqueName = "Hurricanes_" + dt.time.currentTime.strftime("%Y_%m")     outPointFeatures = r"C:\OutputDate\" + uniqueName     ExtractValuesToPoints(hurricaneLayer, rasterLayer, outPointFeatures,                       "NONE", "VALUE_ONLY")     #Set the current time of the data frame to the next time step     df.time.currentTime += df.time.timeStepInterval ...

With a geocoding service it would be possible to send a request to the service using the address and return the result without ever creating a table or feature class. Otherwise I think the simplest thing to do would be to just create and in_memory table and write the address to a field and then write the output to an in_memory feature class. The in_memory input and output would just be temporary in the script. ... View more

ListFields takes a wildcard for the field name, passing in the field name should only return the single field. import arcpy arcpy.env.workspace = "C:\GeoSpatialTraining\GISProgramming101\Exercises\Data" infc= "Streets.shp" fieln="FULL_STREE" field = arcpy.ListFields(infc,fieldn)[0] print field.type ...

Hi Chris -- thanks for the reply. So, simply running the makeaddin.py from say PythonWin will not work?  It seems to create a new .esriaddin file each time! 1. I am unsure if your suggestion will work for me as we are in a Citrix environment.  There is no Program Files\Common Files\ArcGIS\bin\ESRIRegAddIn.exe available to us!  Can that ESRIRegAddIn.exe tool be copied and run from our Citrix environment?  I may have to use one of our server environments that has a full install of ArcGIS 10.1 on it in order to get this add-in built. Unless you have a solution for us Citirx environment people? I am kind of confused, I understood that you had a problem when double-clicking the esriaddin file. The makeaddin.py is just a python script that will zip up all the contents of the addin into a single compressed file with a .esriaddin extension. So yes, it is intended behavior that a new .esriaddin file is created each time. As far as running the makeaddin.py file, you could run it from any Python IDE or if it is already associated with an install of python you should be able to just double-click it. You don't need an install of ArcGIS 10.1 to build the python add-in, all you need is a version of python installed, i am not sure if there is a specific version, but 2.7 would be the best bet. This is because you only need to be able to run the makeaddin.py to build the add-in. To install the add-in, ie double-click the .esriaddin file and pop up the installation utility, you do need ArcGIS 10.1 installed. This is because that utility is ESRIRegAddIn.exe which is installed with ArcGIS Desktop. In regards to a Citrix environment, if ArcGIS Desktop 10.1 was installed on the citrix machine the ESRIRegAddIn.exe should have already been associated with the .esriaddin file extension type for all users on the machine. This is really not specific to Citrix. If you are connecting to Citrix machine that has ArcGIS Desktop installed and attempting to double-click an .esriaddin file and no installation utility is launched it sounds like something broke the default file associations with these files. If that is the case you would want to work with the administrator of the machine to reestablish those file associations for all user. ... View more

This is assuming based on your code that you only need to find MXDs whose first 5 characters of the name is "Copy_": #This is where I am encountering problems with how to only apply changes to mxd's file names that contain 'Copy'              #term = "Copy" #if term in basename: if basename[0:5] == "Copy_": Strings are indexable so what I am doing is returning the first 5 characters of the name of the MXD and testing if it is equal to Copy_ ...

I am having the same problem. I get a big red X on my Toolbox, which means I am unable to open it and even view the potential errors within them. However, when I click "Check Syntax" I get "No Syntax Errors". What does this mean? If there are no syntax errors, what is the problem? If there is an error, why doesn't it tell me where it is? As a test, I added an error, and it was returned when I reclicked "Check Syntax". This seems in all respects to be a bug. Could you post the toolbox? It does sound like a bug. ... View more

Excellent Chris, this works perfectly. Thanks very much. DK P.S. Any idea why elseif is one work but end if is two? I am not sure, but this is consistent with all VB languages. http://msdn.microsoft.com/en-us/library/752y8abs(v=vs.80).aspx ... View more

Check my latest posts on the following ArcGIS Idea for information on a 64 bit version of ArcGIS Desktop: 64 Bit ArcGIS Desktop In addition, at 10.1 you should start to consider if making an OLE DB connection is necessary. We now allow you to make a database connection to any of the following databases even if they don't contain an enterprise geodatabase: �?� IBM DB2 �?� Informix �?� Microsoft SQL Server �?� Windows Azure SQL Database �?� Netezza �?� Oracle �?� PostgreSQL So for the majority of users they will only ever need to use the Add Database Connection command. The only time you would need to use an OLE DB Connection is if you need to connect to a database not in the list above. The original poster was working with SQL Server, so if you use a Database Connection instead you will be able to use this connection in 32 bit or 64 bit background. ... View more
