5. 5 Methodology - Overview of GeoNode implementation architecture. BE-Basic – GeoNode WebGIS

6. 6 Data management Home page and Navigation Bar home page of GeoNode to upload and explore From the home page of GeoNode is posible to upload and explore data and metadata of layers, maps and documents. "layers" are geospatial data in vector or raster format"maps" are layered combinations In GeoNode, "layers" are geospatial data in vector or raster format, and "maps" are layered combinations. One can also change the display language. BE-Basic – GeoNode WebGIS

7. 7 Data management Sign in and Menu options “Sign in” and “MENU” allow the userassign different access editing permissionsswitch applicationset up a “superuser” The “Sign in” and “MENU” options allow the user to assign different access and editing permissions for different users and to switch application such GeoServer and set up a “superuser” account. BE-Basic – GeoNode WebGIS

8. 8 Data management Menu option BE-Basic – GeoNode WebGIS

9. 9 Data management Upload Layers "upload layers" "Explore Layers". After the authentication in GeoNode platform the user can add layers by using the "upload layers" highlighted within the framework "Explore Layers". BE-Basic – GeoNode WebGIS

10. 10 Data management Geospatial data storage upload vector and rasteroriginal projections -GeoNode allows the upload vector and raster data in their original projections using a web form. VectorESRI Shapefile satellite imagery and other kinds of raster dataGeotiffs - Vector data is uploaded in ESRI Shapefile format and satellite imagery and other kinds of raster data are uploaded as Geotiffs. BE-Basic – GeoNode WebGIS

11. 11 Data management Upload Layers it displays an error message After the user selects the files to be inserted, the GeoNode detects the selected file formats. If the format of a given file is not recognized as geospatial, it displays an error message. an error related to the projection unsupported characters such as accents and cedilla There is also the possibility of an error related to the projection of the layer or the use of unsupported characters such as accents and cedilla in both the layer name as the attribute table. BE-Basic – GeoNode WebGIS

12. 12 Data management Upload Layers If the uploading data process is successfully done a message is displayed confirming the files upload ed in the GeoServer. “Layer info" By clicking the “Layer info" option the user is directed to the display of the input data. BE-Basic – GeoNode WebGIS

13. 13 Data management Edit Layers viewing the layersave data on a local or virtual machinecreate a map using the added layer edit the layer download the metadata In addition to viewing the layer, it is possible for the user to save data on a local or virtual machine, to create a map using the added layer and also edit the layer or download the metadata. automatically generated Some items of metadata are automatically generated by GeoNode, while other fields need to be filled by the user. BE-Basic – GeoNode WebGIS

14. 14 Data management Metadata Editing To edit a loaded layer the user simply click “Edit Layer". Then simply click "metadata edit" (highlighted) to complete the required fields and user interest fields. BE-Basic – GeoNode WebGIS

15. 15 Data management Edit layer style modify the format the vector control The user can modify the format the vector (point, line or area) is shown and control the color lines, areas and even entire layers. Each layer has its attributes from which one can create an SLD style (XML document) that can be loaded with the layer or created for the map by GeoNode. TU Delft - BE-Basic - GeoNode

16. 16 Data management Edit layer style edit and create styles like ArcGIS or QGIS One can also edit and create styles using tools like ArcGIS or QGIS, which make it easy to create complex styles. Stylescreatedrulesdetermine colors, scales and labels Styles can be created using one or more rules which determine colors, scales and labels for the layer. TU Delft - BE-Basic - GeoNode

20. 20 Future steps to be implemented 1.Customizing the Look and Feel of GeoNode How to change GeoNode’s main logo, the index page and the colors. The paths to the different locations are assumed to be on Ubuntu with GeoNode installed via packages, but the same notions can be applied in any deployment. BE-Basic – GeoNode WebGIS

21. 21 Future steps to be implemented 2. Customizing the home page Django’s template engine GeoNode uses Django’s template engine, /etc/geonode/templates is empty by default but it is above other folders in the template lookup hierarchy. This means that it is possible to copy any html template to that location and it will take presence. Let’s start by doing the following: sudo cp /var/lib/geonode/src/GeoNodePy/geonode/templates/index.html /etc/geonode/templates. index.html The copy of index.html that was just created takes precedence over the default one, the text in the main section can be changed there and a reload of the web page in the browser will show the updated version. Note Note: Changes to templates are picked up automatically and do not require a server restart. With the same approach, the structure of all pages can be modified by copying and then editing page_template.html. It is recommend reading about the Django template language for advanced customizations. Note Note: While editing the templates in place will also achieve the expected results, it will make upgrading GeoNode harder, therefore it is recommended to follow the approach described above.

22. 22 Future steps to be implemented 3. Changing the default logo Similarly to the way the templates work, GeoNode’s images and css files can be overridden in/etc/geonode/media. The original GeoNode logo is located at The original GeoNode logo is located at /var/lib/geonode/src/GeoNodePy/geonode/media/theme/img/logo-bg.png. Once the logo is placed there, it is necessary to run the media collection command: Make a copy and edit it and then save it in /etc/geonode/media/theme/img/logo- bg.png. Once the logo is placed there, it is necessary to run the media collection command: sudo geonode collectstatic -v0 This will gather all the media in the different locations (both source and the user customizations) and put it in the directory being served by apache: /var/www/geonode/static/. Note Note: It is not recommended to change the files directly in /var/www/geonode/static/ because they are overwritten any time the media collation command is run. BE-Basic – GeoNode WebGIS
