It really feels like those old "static" websites that would try to behave like "dynamic" sites without actually adopting the proper technologies. Instead of selectively updating only what needed to change following a simple user-interaction, the entire page would be re-downloaded and re-rendered even if only a single line of text needed to be replaced. Think your local ISP's clunky online email portal compared to the slick Gmail interface. Apply a definition query with a simple WHERE statement to a featureclass that you've already downloaded 5 second ago and which is read-only on the server? Better re-download the entire thing just to be sure! No bother that you're working remotely over VPN and will now have to wait five minutes for it to reload. Need to slightly change the color of the topmost layer's symbology? Better re-download and re-render all the other layers first! It's more important that the anti-aliasing be perfect. Oh, you want to collapse a pane? Get ready for a slow-motion slideshow of it minimizing while the entire map is repeatedly re-rendered at 10,000 dpi. Want to save your work every few minutes so you don't loose it when Pro crashes? Hope you're ok with a long pause while it writes to disk the fact that you changed the name of a layer. PLEASE make this the highest priority for the development team aside from critical bugs!!! The slowness is causing me to make mistakes since I forget what I was doing while waiting for Pro to catch up.

The party is still ongoing! I have mostly moved on from sharing layers using the KMZ format but ran into this issue again, and Google brought me back to my own post. Using ArcMap 10.7.1 now. I was able to resolve today's instance by exporting the layers having joins to feature classes before exporting to KMZ. Something about the KMZ export tool is incompatible with the way I was joining attribute tables to the layers, I guess. Soon I hope to switch to Pro and will see if the issue has been resolved there...

I fully support and agree with ESRI's decision to re-implement this important feature using SQLite. This is better than the legacy MDB format.

Maybe if I ask the question a different way? I'm trying to build something similar to the Linear Referencing tool "Locate Features along Routes". Locating features along routes—Help | ArcGIS for Desktop

Given a feature class containing point locations another containing polylines, I would like to a) determine which line(s) are within a specified distance of each point, and b) what is the “position” along the line(s) which comes closest to each point. Working in ArcMap 10.4.1 (upgrading to 10.7 soon) with an Advanced license. Will be coding the solution using ArcPy. Input Example: (line 1001 and 1002 are roughly 100 feet apart) Desired Output: Thanks for any advice!

Nice job "selling" SQLite - this sounds like an ideal implementation. Not crossing my fingers on ESRI doing anything that might loosen their monopoly on GIS data, but we can always hope...

Running ArcGIS 10.4.1 I have a map consisting of simple attribute tables which are joined to shapefiles, and symbolized. Extremely straightforward. When I attempt to export to KML/KMZ to share with non-ESRI users, I encounter problems despite the tool generating a "success" message. I was wondering if there's an in-depth list of issues/bugs which I could consult in order to get this to work. I've successfully used the Layer to KML and Map to KML tools before, so there's something about this particular map that's causing problems, and if I knew what that was, I could resolve it and rerun the export successfully. Here are a few details regarding the map: most layer names begin with a number and contain spaces and parentheses symbol type is "Simple Line" (solid colors) symbolization, for most of the layers, is by "unique values" by category Categorized attributes are short text strings All other values is disables or enabled, makes no difference the data-source for each layer is a shapefile (polylines) all layers use the same shapefile the joined attribute tables are stored in an .xlsx file each layer is joined with a different tab from the same Excel workbook the map document includes bookmarks I really can't think of anything "controversial" or "difficult"...it's the general kind of map I've produced many times before. A description of the problems: These occur whether I run the Layer to KMZ against individual layers, or Map to KMZ against the .mxd. I have not taken the time to figure out which particular problem occurs when. Non-exhaustive. KMZ files are produced, but they have a file-size of 1KB (empty) KMZ files are produced, but the symbolization is missing (all lines are solid black) KMZ files are produced and file-size is >1KB, but most individual layers have nothing inside I really have no clue what could be going wrong. In every case the tool runs and generates a "success" message. I've done this many times before, with similar kinds of maps, and have never had these problems, which is why I thought there might be a list of known issues/bugs/limitations which I could cross-check against my situation, and potentially make some simple changes to the map to enable the tools to function properly. Thanks for any feedback!

Thanks Dan. I do have multiple messages (potentially hundreds)....but my three lines of code seems to handle this. Every message ends up on its own line in the text file. So you know how much of a noob I am at Python....I'm not even sure what you're doing with the curly-brackets or asterisk. Will do some edumacating and see what that's about. Thanks!

Is there anything wrong with this very simplistic way of writing geo-processing messages to a plain text file? Being new to Python, I was surprised it was this easy....I must be overlooking something! To clarify, I am intending to write the messages from the last tool which was invoked in the script. f = open(resultLogFile, "a") s = str(arcpy.GetMessages()) f.write(s) ‍‍‍‍‍

Thanks Randy. It looks like the "script tool" would enable the script to be used directly from Arc? Would that be at the expense of not being able to use it via CLI? I'm calling the Python script directly from another application using its command line interface. There are a few functions for which custom-built ArcTools exist (developed in-house) and this is how I'm accessing them, rather than trying to recreate them in the other application's programming language. The end-goal is for the Python script to be seamless to the end-user...they will simply see a black window appear for a moment before control is returned to the other application. So...I want to avoid any situation where the script may "error out" and leave them in a confused state.

I am writing a standalone Python script which involves exporting a geodatabase table to a CSV at a location specified by the user. The script will be called via the command line, and the location is one of the arguments. Ideally, the user would be able to specify the location in a way that's familiar to them. They are not Python coders, and the script is non-interactive so I can't present a dialog box where they select the location. Most likely, they will copy-paste a location from Windows Explorer. There are three areas where I'm seeking assistance: How to pass the location argument if it include spaces. The below approach does not work in this scenario. Shall I enclose the arguments in some delimiter? If so, how do I parse the arguments then? Note that there are other arguments as well. How to split apart outFile into the path and the filename. These will be used by arcpy.TableToTable_conversion(), which requires these as separate parameters. How to reformat the path such that it includes proper escaping such as the double-backlashes. # retrieve outFile from the command line (2nd argument) outFile = sys.argv[2] # represents a filename and path # example: c:\temp\output file.csv # could contain spaces, UNC paths, etc. # split outFile into a pathway and a filename outPath = outFileName = # export targetTable to the file specified in outFile # note: targetTable is created elsewhere arcpy.TableToTable_conversion(targetTable,outPath,outFileName) ‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Unfortunately Simplify Line in 10.1 has a bug too. I can't use it because it requires a tolerance parameter, and there is no way to provide that unless you run the tool in batch mode. Sent from my iPhone

Right now the file (it's actually an oldschool arc/info coverage) is being copied into an in_memory workspace where I do a few things as part of a groprocessing model, including the dissolve. I'll try using a file geodatabase for the scratch workspace, that's a good idea. Sent from my iPhone

Thanks you both. I will provide some images tomorrow. All I can think of is if there's a maximum number of vertices per feature and I'm hitting that ceiling so ArcMap has to discard some. The data represents 14,000 miles of roadway centerlines which are broken into roughly one mile segments, each segment has many vertices. I am dissolving the input on "route number" and there are a few hundred routes, some of which are comprised of 1000+ individual input features. So there must be a large number of vertices.

Running ArcMap 10.1 I am using the Dissolve tool on a polyline shapefile, dissolving on two attributes (not sure if that matters). The resulting output always contains small geometric distortions. It appears that not all of the vertexes are being carried into the dissolved linework. If I reduce the number of input features (subset the geographic extent) the situation improves, but does not go away. Is this a bug? Any solution? I was hoping to rely on this tool but with this happening, it's just too risky. Thanks!
