Hey Justin - you've invoked the name of geocommons so <poof!>

Thanks for your feedback. It's always welcome.

Specific to the dataset you linked - it points to an HTTPS service that has an invalid security certificate. So in this case we should have shown you an message that said the dataset server is not working.

More generally, I'm particularly interested in that tantalizing list of questions and suggestions for improving ArcGIS Open Data (and all of ArcGIS). We deploy updates about every two weeks, and currently are doing a number of redesign & rebuild of functionality, so your input is extremely well timed.

Feel free to start a new thread, or ping me directly - andrew @ <you know who>.com

Hi Justin, as I mentioned in the other issue, the problem was most likely a temporary error in the host server or in the Open Data infrastructure. If you can point out specific downloads that fail, we'd be happy to take a look.

Hi Starla,

When you download the data, what error do you receive?

Also some other questions:

1) What format are you downloading the data in (Shapefile?)

2) Are you downloading the entire dataset, or a filtered dataset?

3) What browser are you using?

Shapefile, KML and table/entire dataset/ Chrome & IE. I read that we shouldn’t publish services with more than 5000 features. Our address points are close to 9000. I republished and used the index button and now it seems to be working. I also have contours I would like to throw up there but the dataset is rather large. Any suggestions when publishing this service for Open Data?

Hi Starla,

Where did you read that you shouldn't publish services with more than 5,000 features? ArcGIS Open Data will support services with more than 5,000 features. Publishing your contours dataset should be fine; creating a hosted feature service on ArcGIS Online will make it more stable and have quicker response times. If you go with an on premises service, I'd recommend changing the download cache to manual in the Data Manager tab of the administrative application (I am assuming your contours will not be a frequently updated dataset), so users get immediate downloads.  More information on the download cache settings here: Data manager—ArcGIS Open Data | ArcGIS

Thanks

I saw it here: http://doc.arcgis.com/en/open-data/provider/server-configuration-details.htm.

I should read more carefully. Thanks!

this just hangs in Chrome - well over ten minutes.

it seems large datasets do this, or just error out.  sometimes Firefox works, but not all the time.  Who is a good POC for questions with regard to ArcGIS Open data website?  There are a ton of things that I think can be updated, or changed for a better end user result.  right now it is super limited (since ESRI bought out geocommons, they should have taken a few pointers from them, but didnt...)

Thanks!

Justin
