Not able to get the preview of KML files.

[shubham-mahajan]

Hi Team

I have installed the extension as per readme, but I am not able to get the preview. No error is coming either in JS or in CKAN. Are there any dependencies that I need to install for ckanext-geoview to work properly.

The preview is completely blank page. Attaching the screenshot for the same.

Loading... The text is coming and after that, it went blank.

Thanks

Hello Shubham,

I tried that resource on a local instance of mine and it worked fine. can you share a link to an online CKAN instance that reproduces the problem?

Hi @pduchesne ,

I am also working on local instance only, but if you require I will set up the same in public instance and share the same. The basic difference I am able to see with a working site and my instance are mainly mapconfig options in the inspection of the elements. Is there any dependency on other extension or Framework?

Can you share your ckanext.spatial. and ckanext.geoview. values from your config? And your basemaps.json config, if you have one.

I have not installed the spatial extension, is it required for geoview to work, it's not there in documentation.

ckan.plugins = stats geo_view text_view image_view resource_proxy ckan.views.default = image_view geo_view ckan.spatial.srid = 4326 ckanext.geoview.ol_viewer.formats = wms kml geojson

OK, I got it.

There's been a regression causing the default basemap to fail. I'll fix that.

In the mean time, to be able to work with your current install, you'll have to explicitly specify a basemap in your config, f.i. :

ckanext.spatial.common_map.type = XYZ
ckanext.spatial.common_map.custom.url = http://tile.openstreetmap.org/{z}/{x}/{y}.png
ckanext.spatial.common_map.attribution = Map tiles & Data by OpenStreetMap, under CC BY SA.

my bad, you should use this (custom type) :

ckanext.spatial.common_map.type = custom
ckanext.spatial.common_map.custom.url = http://tile.openstreetmap.org/{z}/{x}/{y}.png
ckanext.spatial.common_map.attribution = Map tiles & Data by OpenStreetMap, under CC BY SA.

Hi @pduchesne

Thanks for providing the configuration, it's displaying the display. But default, MAP Viewer(Open Layers) is not getting created for KML files/URLs. Is there any option or configuration entry for default view as MAP Viewer for all the KML files.

P.S. Configuration entries used are:-

ckan.plugins = stats geo_view text_view image_view resource_proxy _ckan.views.default = image_view geo_view_ ckan.spatial.srid = 4326 ckanext.geoview.ol_viewer.formats = wms kml geojson ckanext.spatial.common_map.type = custom ckanext.spatial.common_map.custom.url = http://tile.openstreetmap.org/{z}/{x}/{y}.png ckanext.spatial.common_map.attribution = Map tiles & Data by OpenStreetMap, under CC BY SA.

[pduchesne]

the correct config key for default views is ckan.views.default_views, not ckan.views.default

Thanks a lot, everything is working fine now. For default view, it was a typo.
