[GeoNode-users] Base layer is not visible on thumbnail of the uploaded content

[Jonathan Doig]

Hi Naresh

This has been an open issue since 2015. Here is a bit more explanation:
https://github.com/GeoNode/geonode/issues/2025

Also some notes from our own user guide:

  *   Your browser caches images, so the thumbnail may not appear to change. Refresh the page with a ‘hard reload’ (Ctrl + Shift + R on Chrome, see instructions<https://www.getfilecloud.com/blog/2015/03/tech-tip-how-to-do-hard-refresh-in-browsers> for other browsers).
  *   Please be patient, as larger datasets may take several minutes to display the first time. The system builds a tiled image cache for new layers, so subsequent rendering is virtually instantaneous.
Finally, if all else fails and you have access to the server you can create a thumbnail ‘manually’ and FTP it to the uploaded/thumbs folder, overwriting the automatically created thumbnail. To find the filename to use, right-click the thumbnail and select ‘Copy image address’.

Regards
Jonathan

Dear Simone,

  Thanks a lot for answering my query.

  1.  However in case of Map - Thumbail -- when we publish/save the thumbnail is getting generated with the base layer. Please suggest can we do modification in code,
       so that  when we upload the layer , the thumbnail should be generated  with the default selected base layer along with the uploaded content.

  2. Even some times  when we click on SetThumbnail, the thumbnail is not refreshing and  if we reload the page or click on the some other links the thumbnail get refreshers.
      I thinks there is some time delay or refresh problem. How do we over come  this issue?

Thanks&Regards,
Naresh. N

Hi Naresh, that is not possible. The baselayer can only be visible if the client is currently showing a map with it and can send it to the server along with the thumbnail request. This is not available on layer upload.

Dear All,
 After uploading the layer, if we click on layers list, the corresponding layer thumbnail base layers are not visible. If we click  on the corresponding Layers  --> Edit Layer if we click on Set Thumbnail  then base layers along with uploaded content is visible in thumbnail

 Please suggest how to include the base layers also in thumbnail on upload of  spatial data with out manually clicking Set Thumbnail option.

Thanks&Regards,
Naresh
