GeoBrowser does not display kmz file

[emanueldima]

@fungunga For this kmz file: https://infra.clarin.eu/content/VLO_KML/language_sites.kmz the GeoBrowser(KML) does not show anything: no loaded file and also no error.

Is this related to the size of the input file? In any case, an error message is necessary.

Geo-Browser can only display certain KML formats, please see here: https://geobrowser.de.dariah.eu/beta/doc/geobrowser.html#specification-for-use

Error handling has to be enhanced, yes: https://projects.gwdg.de/projects/geo-browser/work_packages/34360

The pdf specifies the following attributes:

And the document given as example has these attributes (the first element as example):

            <Placemark>
                <name>!Xóõ</name>
                <description>genus: Southern Khoisan&lt;br&gt;family: Khoisan&lt;br&gt;&lt;br&gt;&lt;a href='https://infra.clarin.eu/content/language_info/data/nmn.html'&gt;More information...&lt;/a&gt;</description>
                <LookAt>
                    <longitude>21.5</longitude>
                    <latitude>-24</latitude>
                    <altitude>0</altitude>
                    <heading>-0.1094821371621389</heading>
                    <tilt>0</tilt>
                    <range>204302</range>
                    <altitudeMode>relativeToGround</altitudeMode>
                </LookAt>
                <styleUrl>#msn_ylw-pushpin1</styleUrl>
                <Point>
                    <coordinates>21.5,-24,0</coordinates>
                </Point>
            </Placemark>

So is it the lack of a TimeStamp or Link that is causing the failure? Or the presence of additional elements?

I do not really know how this is handled internally, but you can look into the existing examples under “static data“: https://geobrowser.de.dariah.eu/data/boell.kml, error handling sure has to be improved.

A direct Geo-Browser call https://geobrowser.de.dariah.eu/?kml1=https://trep.de.dariah.eu/1.0/dhcrud/hdl:21.T11991/0000-001B-4228-C/data does work just fine.

A Switchboard call with the same object (https://trep.de.dariah.eu/1.0/dhcrud/hdl:21.T11991/0000-001B-4228-C/data) https://switchboard.clarin-dev.eu/switchboard-test/#/trep/https%3A%2F%2Ftrep.de.dariah.eu%2F1.0%2Fdhcrud%2Fhdl:21.T11991%2F0000-001B-4228-C%2Fdata/application%2Fvnd.dariahde.geobrowser.kml%2Bxml links to https://geobrowser.de.dariah.eu/?kml=https%3A%2F%2Fswitchboard.clarin-dev.eu%2Fswitchboard-test%2Fapi%2Fstorage%2F7cae1a3b-33e2-4f65-b4c3-78f242268cdf%3Fmediatype%3Dapplication%252Fvnd.google-earth.kml%252Bxml, and it does not work.

BTW: Direct calls of https://switchboard.clarin-dev.eu/switchboard-test/api/storage/7cae1a3b-33e2-4f65-b4c3-78f242268cdf?mediatype%3Dapplication%252Fvnd.google-earth.kml%252Bxml and https://switchboard.clarin-dev.eu/switchboard-test/api/storage/7cae1a3b-33e2-4f65-b4c3-78f242268cdf are working just fine...

And finally https://geobrowser.de.dariah.eu/?kml=https%3A%2F%2Fswitchboard.clarin-dev.eu%2Fswitchboard-test%2Fapi%2Fstorage%2F7cae1a3b-33e2-4f65-b4c3-78f242268cdf also is working just fine!

Puuh! Sorry for all the URLs :-) Can we prevent the mimetype to be forwarded from the Switchboard to the Geo-Browser parameter? Or would that be an Geo-Browser issue?

@fungunga I am looking at the problems you signalled, but in my opinion the bigger usability problem is a lack of an error message when the GeoBrowser cannot show anything due to missing fields. Can you do something about that?

[fungunga]

Yes, this already is an issue to be fixed: anhancing error handling in geobrowser: https://projects.gwdg.de/projects/geo-browser/work_packages/34360/activity?query_id=505
