[Realtime-feed-users] Detail JSON Structure

[Rogers, Wesley A]

David,

I’d be interested in looking at it – is there a disclaimer? I’d need to get a say-so from our licensing people.

I have a Visual Basic 2010 class specifically written to decode USGS, Canadian and New Zealand GeoJSON files if it is on any interest. I can provide a link to the file if you are interested.

Hi,

The simplest use of these feeds is in javascript, which natively supports JSON.  An example of this is our Latest Earthquakes application at:
http://earthquake.usgs.gov/earthquakes/map/
The source code for this is on GitHub at:
https://github.com/usgs/earthquake-latest-earthquakes


There is also a Java library that parses the GeoJSON feeds, or search API which supports the same formats, at:
https://github.com/usgs/earthquake-event-ws-client
This uses a json library for parsing, and then a wrapper object that manages access into the structure.


There are also examples for Python, Matlab, and R, in this github repository:

Thanks,

Jeremy

Thanks – I saw that this morning and subscribed. I am having major problems deserializing this section of your schema, where there is a set of objects (but not an array) that have variable names. Dictionary<string, object> is not working. How does your group do it?

Hello,

Based on user feedback, we set up a separate mailing list specifically for realtime-feed questions.  The realtime-feeds list will only be used to announce changes to the feeds moving forward.

I forwarded your message and a reply to that list, but forgot to cc you on my reply:
    http://geohazards.usgs.gov/pipermail/realtime-feed-users/2014-April/000001.html

Please subscribe to the new list here:

Thanks,

Jeremy
