Datarecords neatly stacked in pairs? I wish Records in the testdata are paired and sequenced after timesteps -great! But in the real application of the system I’m trying to make I need it to work despite a discrepancy in datafeed frequency (eg. radar every minute, AIS every 5 minutes etc) –not so great. This is one of my main headaches, as I just don’t see how to compare two geoevents from different datastreams with varying feed frequencies. The 715 value is an example of a rogue value, yes. My current workaround consists of filtering the radardata, making it a polygon geometry and the storing it in a “dummy” service. Then I use a proximity filter that opens when AIS geoevents intersects with a radardummy polygon (imported via a geofence sync-rule) to enrich the intersecting AIS geoevent with fields from the radardummy. THEN, I am able to verify my AIS data by comparing the enriched fields from my radardummy with the original AIS fields.. It works.. But it just seems very clunky, and prone to error, and since the sync-rule for my geofences only update every minute, the system will never be as responsive as I would like it to be.

Can the radar feed be thought of as almost a "lookup"? Yes, it only serves as a comparative verifier of the AIS signals’ validity For example, is it an accurate statement to say that for any message you get from the AIS stream, there's a related record in the radar stream? yes If so, would MMSI be the common identifier? Could be. Right now we are comparing based on geometry Does each feed have the same schema, or completely different? Not exactly similar, but some similarities (vessel size, speed) If completely different, and there's no MMSI to "join" on, what piece of data is the logical link between the two streams (i.e. "join field")? MMSI is probably the way to go on real data but in our tests we run with IMO Is there any way you could send me sample data of each feed? Event just like a couple records from each, not a large history...

Yeah, I’ve tried working with a dummy feature service and use the spatial query extension to append my data, but I’ve not been able to make it work. If you know of a more obvious/direct solution I would be happy to know more! My case is this: I have a maritime radar datastream and a ship AIS datastream. The radar datastream is considered to always be “correct”, and the AIS data (entered by the skipper) is considered “rogue”. I wish to be able to monitor these datastreams, and compare them to each other to look for discrepancies (ship size, location, bearing etc.). To do this I need a method of querying and comparing one datastream to another. As you say, the solution probably lies in a model that has a certain data persistence. I will be grateful for any knowledge/help you can provide! /cheers Fra: Mark Bramer Sendt: 3. januar 2017 23:26 Til: Mikkel Sandermann Olsen <mikkelo@informi.dk> Emne: You have been mentioned by Mark Bramer in Re: compare geoevent field values in GeoNet GeoNet <https://community.esri.com/?et=notification.mention> You have been mentioned by Mark Bramer<https://community.esri.com/people/MBramer-esristaff?et=notification.mention> in Re: compare geoevent field values in GeoNet - View Mark Bramer's reference to you<https://community.esri.com/message/656772-re-compare-geoevent-field-values?commentID=656772&et=notification.mention#comment-656772> ...
