Running the Map to KML tool

CoyPotts1

I am trying to create a script that will apply a symbology layer to the current map, save the map, export the map to KML, and then reapply the original symbology from a layer file.

Apply symbology from layer file:

# Import system modules import arcpy from arcpy import env # Set the current workspace env.workspace = "file path where layer files are saved" # Set layer to apply symbology to inputLayer = "layer file name" # Set layer that output symbology will be based on symbologyLayer = "feature class within map" # Apply the symbology from the symbology layer to the input layer arcpy.ApplySymbologyFromLayer_management (inputLayer, symbologyLayer)

This part works fine.

Save the map:

# Set up map variable 

import arcpy.mapping as map 

# Set map variable to current mxd mxd = map.MapDocument("CURRENT") 

# Save the map document mxd.save()

This part works fine.

Map to KML:

# Set environment settings

arcpy.env.workspace = "haven't figured this part out yet"

# Set Local Variables

dataFrame = 'Layers'

# Sets the KMZ name to be equal to the mxd

outKML = mxd+'.kmz'

#Execute MapToKML

arcpy.MapToKML_conversion(mxd, dataFrame, outKML)

This is the part that I'm having trouble with. I'm not entirely sure how to correctly construct the Map to KML portion. This script will be run on many different maps and the workspace for each map will be identical to each other with the exception of the map name. I tried to set the workspace to the following path, with no luck:

arcpy.env.workspace = "folder1\folder2\folder3\" + mxd + "\folder4\folder5"

But this results in this error "Parsing error SyntaxError: unexpected character after line continuation character (line 1)

Apply symbology from layer file:

Simply a repeat of the previous iteration of the tool with a different layer file.

Now...I need to get the output kmz and workspace to be dynamic instead of static. I'll play around with the getparameterastext functions and see what I can come up with.

JeffWard

The documentation is wrong. The first parameter doesn't take the mxd object, it takes the path.

dataFrame = arcpy.mapping.ListDataFrames(mxd)[0].name
arcpy.MapToKML_conversion(mxd.filePath, dataFrame, outputKML)

I put in Carl Sunderman's bit to get the name of the first data frame in the map.

CoyPotts1

How do I make it hold the actual data frame instead of a string variable?

CoyPotts1

The data frame does have the same name as the mxd.

I did as you suggested above and I still got the exact same error as above.

Question regarding your suggestion, though:

I thought that the line that sets the current workspace (line 39) within Part 3 was taking care of where the outputKML would be saved...?

DarrenWiens2

Your dataFrame variable holds the name of the map, not the required data frame name, unless they happen to be the same.

CarlSunderman

Does your dataframe name match your mxd name?

Hardcode the output path and see what happens.

outputKML = "C:\\<insert stuff>\myfile.kmz"

No you don't need all inputs, if there are any that you are skipping you'll need to account for those like:

(stuff1, stuff2, , more stuff, , etc)

CoyPotts1

I actually finally got one of the above suggestions to work in regards to getting the map name as a string. Their suggestion wasn't properly written, so it didn't work for me. I changed ".filepath" to ".filePath" and it worked like a charm.

Here is the latest run and error message for the entire code:

There's something with my execution of the MapToKML tool that it's not liking. The three variables that I used in the MapToKML execution are the three that are required inputs. Do you think that it requires that all 10 inputs be included?

CarlSunderman

Paste your complete code.

Try

import os
import arcpy

<SPAN class="pun" style="color: #145680;"></SPAN><SPAN class="pln" style="color: #000000;">mxd </SPAN><SPAN class="pun" style="color: #145680;">=</SPAN><SPAN class="pln" style="color: #000000;"> arcpy</SPAN><SPAN class="pun" style="color: #145680;">.</SPAN><SPAN class="pln" style="color: #000000;">mapping</SPAN><SPAN class="pun" style="color: #145680;">.</SPAN><SPAN class="typ" style="color: #2b91af;">MapDocument</SPAN><SPAN class="pun" style="color: #145680;">(</SPAN><SPAN class="str" style="color: #800000;">"CURRENT"</SPAN><SPAN class="pun" style="color: #145680;">)</SPAN>
<SPAN class="pln" style="color: #000000;">mxdLocation = mxd</SPAN><SPAN class="pun" style="color: #145680;">.</SPAN><SPAN class="pln" style="color: #000000;">filePath</SPAN>

head, tail = os.path.split(mxdLocation) 
mxdname = tail.replace(".mxd", "")

It seems you are getting there.

Edit:

had to fix mxdLocation, case on in line 7 to match line 5.

JeffWard

Try using GetParameterAsText for your model variables inside your script. Python is interpreting '%saveKML%' as strings.

env.workspace = arcpy.GetParameterAsText('0')
outputKML = arcpy.GetParameterAsText('1') + '.kmz'

JeffWard

Unless it's a network path - doh!

CarlSunderman

I normally hardcode values like inputs and outputs until i get everything working, then start adding the variables.

I would skip using model builder since you have all the python in the above comments to get it working. I personally have never used it

The "t" was only in the version that I had written in NotePad. The code above is what I had typed into the actual ArcMap Python window.

CoyPotts1

Heh, I do have a t in there . I'll see tomorrow what I get when I take that out.

I think it's about time to give this a rest for tonight.

DarrenWiens2

Don't know if this is the whole problem, but "conversion" is spelled wrong.

CoyPotts1

I haven't had much of an opportunity to test out the suggestions for pulling out the mxd name, but I have a script that runs all the way up to the MapToKML portion.

# Name:  Map To KML
# Description:  This script is used within a model to export the map to a KMZ file for distribution.
# Author:  Coy Potts
# Parts: (1) Apply Symbology Layer File, (2) Save mxd, (3) MapToKML tool, (4) Apply Symbology Layer File

# Import system modules
import arcpy
from arcpy import env
import arcpy.mapping as map

# Part 1:
# Apply Symbology Layer File

# Set current workspace
env.workspace = r'\\company.local\dfs\dept_name\1)folder\folder\layerFiles folder'

# Set layer to apply symbology to
inputLayer = r'\\company.local\dfs\dept_name\1)folder\folder\folder\layerFile.lyr'

# Set layer that output symbology will be based on
symbologyLayer = r'DataFrame\FeatureClass'

# Apply the symbology from the symbology layer to the input layer
arcpy.ApplySymbologyFromLayer_management (inputLayer, symbologyLayer)

# Part 2:
# Save the map

# Set the map document to the current map
mxd = map.MapDocument("CURRENT")

# Save the map
mxd.save()

# Part 3:
# Map to KML tool

# Set current workspace
env.workspace = '%saveKML%'

# Set local MapToKML tool variables
inputMap = mxd
outputKML = '%outputKML%' + '.kmz'

# Execute MapToKML
arcpy.MapToKML_converstion(inputMap, outputKML)

I went ahead and set the script up to grab two variables that are within a model builder model. The saveKML is the file path to be input by the user, and the outputKML is the name of the KML file, also input by the user.

Originally I set this script up in NotePad, saved as a .txt file, loaded into the ArcMap python window, saved as a .py script. From there I loaded it into a script inside my toolbox and then inserted that script within the model with the two variables. When doing it this way I got an error that said syntax error on line 2, but I couldn't figure out why. So I went and manually entered the entire script into the ArcMap python window piece by piece, and it was all working up to the point executing the MapToKML tool. Once I pressed enter after that line, it kicked back the following error:

"Runtime error

Traceback (most recent call last):

File "<string>", line 1, in <module>

File "c:\program files (x86)\arcgis\desktop10.3\arcpy\arcpy\conversion.py", line 2278, in MapToKML

raise e

RuntimeError: Object: Error in executing tool"

Everything up to that point ran just fine.

JeffWard

After looking at this, this comes back as a single element list.

This might be better:

mapname = str(mxd.filepath).split('\\')[-1:][0][:-4]

CarlSunderman

As far as getting the file name, i'm not sure of a real elegant way, but i'm sure there is.

Perhaps you could use

import os

#os.path.split(path)
head, tail = os.path.split("C:/tmp/myfile.mxd")
#head, tail = os.path.split("//tmp/myfile.mxd)

>>>print tail
myfile.mxd

or something along those lines. then strip off the mxd.

this would work for "/" as well as "\"

JeffWard

filePath1 = r"\\company.local\dfs\dept_name\gis_folder\projects\"

You need to take out the double backslash at the beginning of this if you are going to preface it with r.

JeffWard

How about:

mapname = str(mxd.filepath).split('\\')[-1:]

This gets the path of the map document, converts it to a string, splits it by the double backslash and puts the last element in mapname.

Edited to fix my hasty slicing error.

CoyPotts1

Thank you Jeff, I will note that for future reference.

CoyPotts1

Okay, that is also helpful. I'll go a little deeper into explanation. A sample file path is listed below (renaming the actual folder names for proprietary purposes):

\\company.local\dfs\dept_name\gis_folder\projects\region\region-state-name-carrier\deliverables

That is the full file path that I would be working with. We name the maps identically to the "region-state-name-carrier" naming convention (e.g. "NC-IL-MYHOUSE-VZW"). The mxd is saved at this stage of the file path. Once we create a KML output from the mxd, it is saved in the deliverables stage of the file path.

I thought that since all file paths are identical with the exception of the "region\region-state-name-carrier" portion, I could just make static variables for "\\company.local\dfs\dept_name\gis_folder\projects\" and "\deliverables", and use the map name as the dynamic variable that will change from project to project. Essentially I need to take the map name and convert it to a string. I would take that string and strip out only the first two characters to uses as my "region", and then I would use the whole string as my "region-state-name-carrier" portion. I'll list the potential variables below for a better understanding.

mapname = mxd

- I haven't figured out how to do this yet. This is where I want to turn my map name into a string.

region = mapname[:2]

- I haven't figured this part out either, but through google I found that this is one way to strip parts of a string apart, I but it wasn't working when tried.

filePath1 = r"\\company.local\dfs\dept_name\gis_folder\projects\"

filePath2 = r"\deliverables"

arcpy.env.workspace = filePath1 + region + mapname + filePath2

if that doesn't work I am brainstorming and thinking this might work for the workspace:

workspace = filePath1 + region + mapname + filePath2

arcpy.env.workspace = workspace

I'm only thinking of this because the arcpy.env.workspace function might not like concatenating the multiple variables...but I really don't know .

Thanks for your input so far!

JeffWard

Here's how to post code snippets in GeoNet.

DarrenWiens2

As far as I can tell, your main problem with:

arcpy.env.workspace = "folder1\folder2\folder3\" + mxd + "\folder4\folder5"

is ending your string with \" which translates to an escaped quotation mark, or literally the symbol ". That part of the string never closes. For paths, you should use r"path\path", or "path/path" or "path\\path".

Furthermore, the easy way to concatenate paths is by using os.path.join, which uses the system path separator to join path strings:

>>> import os.path
... first_concat = os.path.join(r"C:\folder1\folder2\folder3","someMapName")
... print first_concat
... second_concat = os.path.join(first_concat,r"folder4\folder5")
... print second_concat
... 
C:\folder1\folder2\folder3\someMapName
C:\folder1\folder2\folder3\someMapName\folder4\folder5

CoyPotts1

An additional question...what IDLE do you use to get the numbered structure next to each line of your code? I have been using the python window within ArcMap just because that's all I know to use, but I don't really like it all that much.

And thank you so much for the response!

CoyPotts1

Okay, I sort of understand that. And yes, I was playing with other variations and I was getting the error saying that I couldn't mix a string and a map document, but I couldn't figure out how to translate my map document into a string like ymou do in your exaple.

I'm very green when it comes to Python scripting, so I'm not sure how to correctly answer your question regarding the workspace vs. output. The tool needs to have a workspace in order to know where to save the KML, correct? An alternative, and I think it's what you are showing above, is that you simply create the variables as you show, and then set outKML to equal the concatenation of those variables. So instead of saying save this output in this workspace, you're saying that the output KML equals the entire file path. Am I understanding that correctly?

In regards to the mxdname = "mystring", can you say mxdname = mxd? Or would that still have it be referencing a map document instead of turning it into a string. I'm just a little unclear on how to take my map document's name and add it into the whole folder path.

CarlSunderman

You want the output set like that, not the workspace, i think?

and the mxd name should be passed as a string

output = "folder1/folder2/folder3/"
mxdname = "mystring"
arcpy.<whatever>(output + mxdname + "/folder4/folder5/";
