I'm using the GeoEvent Processor for analyzing georeferenced Tweets concering the weather in the Netherlands. The tutorial (introduction & twitter) provides information about visualization with the Operations Dashboard Application. Unfortunately, that application does not work on my computer due to an old version of Windows.
What are the other options for visualizing the georeferenced tweets (on a map), besides Operations Dashboard?
The Twitter tutorial is being reworked for the 10.2.1 product release. The approach above will be reflected in the tutorial. Twitter's terms of service prohibit developers from caching or storing data harvested from tweets - which means that you cannot use the GEP Cache or Feature Service outputs and remain compliant with the Twitter TOS.
Attached is a PDF with draft material from the tutorial which is currently being developed. Hope this helps you in the near term.
I tried out the tutorial, but it looks like I'm missing the correct data for the streamlayer. Step 11 and 12 wants you to add data to your �??<GEP install folder>/assets�?? directory, but I do not have that data. Could you provide the correct data?
Sorry for the confusion ... using a stream layer to visualize the geographic locations contained in tweets should be compliant with the Twitter "Rules". We are reworking the tutorial exercise to not collect the twitter content in a feature class; this I feel is a violation of the terms of service.
I've attached a file 'WebSocketsSupportFiles.zip' which contains the supporting files from a draft tutorial on working with WebSockets.
I tested the tutorial with the data and it worked, thanks for that!
Now I want to use it for my case: visualization of georeferenced tweets. I used a Twitter input, with a Filter (geolocated = true) and connected this to the stream layer output. The tweets are visualized by dots on the map, but I want more information than just the dot. I would like some information about the message and the time of the tweet.
Is it possible to adjust the streamlayer to my own wishes? And how?
If you look in the attached Twitter.zip archive you'll find a TwitterStreamLayer.html which was updated for the revised Twitter tutorial. (This tutorial should be up on the product gallery soon...)
