    Hi Gareth,

     

    The HTML5 viewer supports GeoRSS feeds as long as the features are points. You can find more information in section 20 of the current Essentials admin and developer guide.

     

    The Voyager extension is exclusive to the Silverlight viewer. I have not tried to consume Voyager RSS or GeoRSS in the HTML5 viewer, myself, but I expect it would work as long as the features were points. I'll ask around the office to see if anyone else has tried this -- it's possible someone in the professional services team has.

    Thanks Jordan,

     

    does this though apply to GVH 2.6?

     

    Currently they I'm trying to display point data, without a lot of luck.

    Yes, what I said above should be true for Essentials 4.5 and GVH 2.6, as well.

     

    Are you seeing the GeoRSS feeds display in Manager and not the viewer? Or are you not seeing them in either?

    Chris,

     

    I got this back from AAM yesterday...

     

    Hi Gareth,

     

    I have been doing some testing and I have not been able to get any Atom GeoRSS services working in my viewer.

     

    Atom GeoRSS (http://www.w3.org/2005/Atom) doesn’t seem to work at all…

     

    (Example https://emapdev.ffm.vic.gov.au/RSS_Feeds/vicroads.xml) which uses this format to georeference.

     

    <point xmlns="http://www.georss.org/georss">-37.7329139322758 144.917984481626</point>

     

    But W3C geo GeoRSS does work (http://www.w3.org/2003/01/geo/wgs84_pos#)…

     

    Example http://www.gdacs.org/xml/rss.xml which uses this format to georeference.

     

    xmlns:geo=“http://www.w3.org/2003/01/geo/wgs84_pos#”;

     

    <geo:Point>

     

    <geo:lat>21.5277</geo:lat>

     

    <geo:long>145.3819</geo:long>

     

    </geo:Point>

     

    I will inform our Senior Tech team of this but I suspect it might be a ESRI API issue.

     

    I tried the older viewer that you said was working 2.5.x but it didn’t work for me, however I am calling the API from ESRI rather than locally.

     

    I suspect the API supplied with Geocortex may differ and this might be the version that is working for you.

     

    I’ll let you know when we have any further correspondence on this matter.

    And this just now...  :)

     

    Hi Gareth,

     

    I fairly confident that it must be Latitude code that must be causing the issue.

     

    I note that Latitude is currently using the 3.17 API (the latest release from ESRI is 3.19)

     

    Using ESRI code based on the API it seems to work fine, (see this page I put together http://geocortex-dev2.aamgroup.com/rssFeed.html that is based on https://developers.arcgis.com/javascript/3/jssamples/layers_georss.html, but I am calling the 3.17 API using the following call <script src="https://js.arcgis.com/3.17/"></script>).

     

    I will make sure that this is raised with Latitude ASAP.

    Thanks Gareth. I'll forward this to the viewer team.

    Follow-up: this is indeed a bug (GVH-13153). The viewer is expecting a "georss" namespace prefix, specifically, on the XML elements in the RSS, as it is shown in the (http://www.georss.org/index.html) GeoRSS spec 's examples. If that prefix is missing, the XML isn't parsed correctly, even though it may still be perfectly valid.

     

    For example, this will be parsed correctly: <georss:point>45.256 -71.92</georss:point> But this will not: <point xmlns="http://www.georss.org/georss" >45.256 -71.92</point>

     

    You may be able to work around this issue by changing the XML itself, either at its source (if you have that access) or via a proxy. It may also be possible to change the namespace prefix simply by running the feed through an aggregator. This issue will be fixed in the 2.8 HTML5 viewer.

    Hi. Jordan, 

     

    I am also having issue with georss feed.  In the rest manager, when I add the geo rss, the feed is displayed on the map, however when in the viewer, the georss feed cannot displayed.  I got error "unable to load proxy?..."

    Hi Hwa,

     

    You might need to review the HTML5 viewer proxy.config and ensure the domain for the RSS feed has been added. 

     

    Proxy.config

     

    C:\inetpub\wwwroot\Html5Viewer

     

    Add a new line like the one below before the </serverUrls> tag and ensure it's pointing to the correct address.

     

    <serverUrl url="http://www.myrssservice.com/" matchAll="true"></serverUrl>

     

    Thanks,

    Hi Jordan,

     

    We are having the same issue with georss feed.  In the rest manager, when we add the georss, the feed is displayed on the map, but in HTML5 viewer the georss feed is not displayed. We have upgraded to GE 4.9 and GHV 2.10. Please suggest some work around.

     

    I have also modified Proxy.config as suggested by Mike.

    I got a solution to the above issue.

     

    To view content from a KML or GeoRSS layer that contains HTML markup, you need to enable the Allow Unsafe Content setting for your viewer.
