Hi Kanchana, If you don't have a version of ArcGIS installed on your computer you won't be able to access the arcpy module with python. An other really easy way to convert spatial formats with python is to use GDAL/OGR. This link will walk you through how to write to kml: Geometry — Python GDAL/OGR Cookbook 1.0 documentation

I am trying to create a python toolbox that allows the user to enter LiDAR surface constraints. The surface constraints input can consist of many feature classes with each feature class having a drop down list that lets the user select a field (z index/elevation) that is associated with the feature class and a second drop down that lets the user select the surface constraint type. The getParameterInfo() code looks like this: #Parameter to hold one or many surface constraints param1 = arcpy.Parameter( displayName="LiDAR Surface Constraints", name="in_surfaceConstraints", datatype="GPValueTable", parameterType="Optional", direction="Input", multiValue=True ) param1.columns = [['DEFeatureClass','Constraint Feature'],['GPString','Height Field'],['GPString','Constraint Type']] param1.filters[1].list = ['<none>'] param1.filters[2].type = 'ValueList' param1.filters[2].list = ['Anchor_Points', 'Hard_Line', 'Soft_Line', 'Hard_Erase', 'Soft_Erase', 'Hard_Replace', 'Soft_Replace', 'Hard_Clip', 'Soft_Clip'] In the updateParameters() class I think I need to update the param1.filters[1].list or add append a filter to each individual surface constraint feature class. The closest I have come so far is to append all the fields to one filter. I have attached a screenshot of the toolbox input that is from the Create LAS Dataset that is native to ArcGIS for Desktop. I am trying to recreate a portion of that that will link up with the rest of my python script. Hopefully that explains my predicament. Cheers, Zack

Were you ever able to figure this out? I working on a similar type tool. Getting a distinct field list/filter for each individual feature class seems impossible. I am creating a script for LiDAR input with surface constraints that can have a z index field. It must be possible as the toolbox parameters work from model builder but setting it up out of a python script is a bit of a mind bender. Zack

Hi Heath, I have had my struggles with Data Driven Pages as well. That is how I got into using python scripting, definitely the best technical decision I have made in my career. If you find you are needing to do this process frequently I would definitely recommend taking the time to write a python script using arcpy. However, there are non python alternatives. I have used Microsoft excel and .bat files to quickly rename the files in a folder and there are batch rename utilities out there such as this one: http://www.bulkrenameutility.co.uk/Main_Intro.php. The excel/.bat file method is difficult to explain on here, but if you are interested in it I can try walking you through it.

I definitely understand your predicament Will. I used to make maps for an Archaeology consultant that thought cartography was based on a strict set of rules and allowed for no variation on it. I ended up automating as much of the process as I could using scripts, layer files and templates and then used the extra time to find new data sets and explore new techniques for making maps that hopefully someone would appreciate. It allowed me to be available for special more interesting projects that would come up while the other GIS Techs were bogged down in their day to day tasks, which they seemed to be comfortable and happy with. I saw blogging mentioned in one of the topic above. I think something like that might help get out of a rut. Maybe there is a place online where people can share maps or ideas? An instagram for cartographers maybe?

Thanks all for putting on a great MOOC! I really appreciate the videos and discussions. It is interesting to hear the thoughts, ideas and pet peeves of the hosts. My question for the panel is what are your favorite digital cartographic techniques and what techniques do you find most challenging? Cheers, Zack

@Omar Mcdoom I think the answer to your question can be found here: Format for CSV to import as polygons (rectangles)?

I find playing with line width and transparency the best way to work around maps where there can be a lot of line overlap.
