Publishing Vector Time Series

Publish Temporal Shapefile through GeoNode

• From the folder /opt/data/sample_data/gisdata/data/good/time upload the file boxes_with_date

  

• The upload starts, but it will stop at 50% asking to the user for further inputs

  

• Click on the play button, you will be redirected to a summary page with the list of the available temporal dimensions

  

• Enable the time check, select the date field and click on next; it will take some time to finalize the upload. When finished you will be redirected to the details page

  

• Click on Editing Tools > Metadata > Wizard and switch to the Settings tab; you’ll notice that the Has Time checkbox has been enabled

  

  When che Has Time checkbox it enabled, GeoNode asks to the OWS Service for the time dimension values

• Notice the time slider now has been enabled on the map.

Publish Temporal Dataset through GeoServer

• Let’s prepare the datset first; we will restore some DB tables and create the layer on GeoServer

• Open a terminal window and execute the following commands

    cd /opt/data/sample_data/user_data/storm_track_sql
    createdb -U postgres -O geonode storm_track_sql
    psql -U postgres storm_track_sql -c "CREATE EXTENSION postgis;"
    psql -U postgres storm_track_sql < storm_track_sql.db
    psql -U postgres storm_track_sql -c "GRANT SELECT ON TABLE storm_obs TO geonode;"
  

  That will create a new DB and restore a table of the historical storms from an existing dump.

• We need to create the layer on GeoServer first; as an admin move to the GeoServer admin gui, click on Data > Stores and then Postgis Data Store

  

• Provide the connection parameters to the new DB

  • Name: storm_track
  • Description: storm_track
  • Database: storm_track_sql
  • Username: geonode
  • Password: geonode

  

• Click on Publish on the next window

  

• Compute the Data Bounds

  

• Click on the Dimensions tab and enable the Time Dimension as shown here below

  

• The layer is ready and published on GeoServer, we need to import it on GeoNode now

• Move to the terminal window, enable the geonode virtual environment and move to the folder /opt/geonode; execute the updatelayers management command as follows

    workon geonode
    cd /opt/geonode
    ./manage_local.sh updatelayers --skip-geonode-registered -u test_user1 -w geonode -f storm_obs
  

• The new layer will be created on GeoNode, it will show only a single point without the timeslider

  

• Edit the metadata and enable the Has Time checkbox

  

• Save it and go back to the details page

  

• Upload the storm_obs.sld style file from the folder /opt/data/sample_data/pretty_maps/styles

  

  

• Go to the Layer View, expand the timeslider and try to move through the valid temporal instant and intervals
