Custom Symbology in Python

AdamBakiera — Tue, 21 Jul 2020 14:57:54 GMT

Good morning,

I have a client that needs individual KMZ layers exported fairly regularly. They also need the layers to have a custom symbology that needs to stay consistent. Most of the layers use unique values for their symbology. The layers are housed in an enterprise .sde. I was hoping to have everything in one .mxd and set up a script to utilize the 'map to kml' tool. Unfortunately, they won't accept a file that includes all of the layers Does anyone know of a way to accomplish this using python?

If I understand correctly you're looking for a script to look at all the layers in the MXD then export them as individual KMLs with appropriate names?

It would be great if I could get it to work with the .mxd because that would eliminate the need to have to write code for custom symbology.

Do you have any experience with python/arcpy? Or do you just want it written for you? It's pretty simple either way.

I have some experience but I'm far from expert level. Now that I've thought of this a little more, I think maybe I was overthinking. If I can set the workspace to be the .mxd and just have several 'layer to kml' lines, that should work, right?

Sort of, turn your mxd into a MapDcoument object then use ListLayers to get the layer objects in the MXD. You should then be able to pass that list layer Object into the layer to KML tool,

something like below but I've probably mistyped something

import arcpy, os

mxd = arcpy.mapping.MapDocument(r"C:\Project\Project.mxd")

df = arcpy.mapping.ListDataFrames(mxd, "")[0]
for lyr in arcpy.mapping.ListLayers(mxd, "", df):
    workspace = a folderpath to write kmls to
    outKML = create a path with something like os.path.join(workspace, lyr.name)
    arcpy.LayerToKML_conversion(layer, outKML)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
