Trying to follow along here, but having a bit of trouble.

1. Visited https://www.unidata.ucar.edu/software/idv/webstart/IDV/

2. Got Unidata IDV running locally

3. I was then able to add the data source via URL and saw two options in "Field Selector": "Image Collection" and "Omni Control".

I've tried selecting either field and clicking "Create Display", but nothing ever appears in the "Displays" tab. Would welcome further advice or more specific reference to directions among the 16 videos in your YouTube playlist. Thank you!

This may be related to some of the errors[1] that seem to occur on startup of IDV.

I found that downloading IDV at https://www.unidata.ucar.edu/downloads/idv/current/index.jsp and not using Webstart resolved the startup errors I reported above and now I see the Map View. However, I'm still not able to get any data to render on the map. Would love help still!

@bbuchalter Thanks for registering and downloading. We like it when our users register because we have to report usage metrics back to our NSF sponsors. Are you able to load the catalog (the .xml not .html suffix for the catalog URI) in the IDV dashboard, Data Choosers tab, and see the NCML files available at that resource?

@julienchastang thanks for your reply. I don't believe I'm able to see the NCML files. I've put some screenshots together here in sequence: http://imgur.com/a/4oI3q#0

1. Add the catalog.xml in the Data Choosers

2. Select Image Collection in the Field Selector and click Create Display

3. The error I recieve when I click create display: "Unknown XML root:catalog"

4. The subsequent Image Collection screen which I'm not sure how to use.

Thank you again for continuing to engage with me on this.

@bbuchalter WRT the screenshot, you are in the URL node where you should instead be in the Catalog node.

That worked! Thank you!

@bbuchalter I know you eventually downloaded the Desktop rather than Webstart version of the IDV and got that to work (this is the preferable option anyway, Webstart can be flaky), but just for the record, I believe you have to update Java on your host by going to java.com.
