Creating and Editing Data

Create an Empty Dataset

• Click on Add Resource > create dataset

  

• Fill the form with some values; first of all insert a name and title and select Polygon as geometry type

• Add three attributes and click the Create button

  • label: String

  • value: Float

  • date: Date

  

• GeoNode will create the new empty dataset with the selected geometry type and attributes and will redirect you directly to the detail page

  

Edit the Dataset Data

• Click on Edit > Edit Data

  

• Click on the pencil to enter the edit mode

  

• Click on the add New Feature button

  

• Click on the pencil again

  

• Draw a small polygon over the dataset and click on the floppy disk button to save

  

• Double-click on the attributes table columns to enable the edit mode on the values

  

• Insert some values as shown below; the date-time attributes must be provided in ISO format

  

• Save and repeat the operation as many times you want

• Once finished, go back to the dataset detail page; you will notice that GeoNode will show some features, but the bounding box is still the whole world; remember to clean the image cache of the browser to show the new features

  

Update the Dataset Bounding Box

• Logout and login again as an admin; from the context menù, click on GeoServer

  

• If you are still logged in as test_user1 on GeoServer, follow the steps below

  

  

  

  

• Go to the GeoServer Data > Layers section

  

• Select and click on the Test layer you just created

  

• Scroll down to the Bounding Boxes section, update them as shown in the figure, and Save

  

• In order to allow GeoNode getting the updated bbox you can either:

  1. Edit the Metadata again and just click on the Update button

  2. Running the updatelayers management command from the Python shell

     • Open a new terminal window and move to /opt/geonode

     • Run the following commands

     cd /opt/geonode/
     workon geonode
     ./manage_local.sh updatelayers -f test_layer
     

• Go back to Test layer detail page and refresh now the dataset will be zoomed on the right location

Delete Data

• Enter the Edit Data mode again

• Select (click over) a polygon and click on the Trash Bin icon

  

• Confirm the deletion and verify the polygon disappeared from the map

  

• Go back to the dataset details page, refresh the browser image cache, and verify the feature is not present anymore
