Introduction
GeoNode is an Open source web based platform for sharing geospatial data and maps.
GeoNode is an Open source web based platform for sharing geospatial data and maps.
GeoNode is platform for developing geospatial information systems (GIS) and for deploying
spatial data infrastructures (SDI). It is designed to be extended and modified, and can be
integrated into existing platforms." GeoNode is a Web Application used for



Upload, manage, and share geospatial data
Create and share interactive maps
Collaborate and interact with other users
1.1 Objectives
The overall aim of the GeoNode Training Package is to increase the understanding and
awareness of the benefits of sharing data and geospatial information through open source
web-based systems, such as GeoNode. Specifically, the purpose of this guide is to provide a
comprehensive manual on how to use GeoNode more effectively and provide practical
training on how to achieve this.
At the end of the training modules, it is expected that GeoNode user will be able to:
• Understand basic concepts of using an open source web-based system for sharing
geospatial information.
• Access and analyze the risks from flood, landslide and strong wind hazards at the Suco
sub district or district level
• Produce comprehensive and illustrative maps by using existing data layers or by creating
new data layers.
1.2 Terminology
FEATURES
Geographical points on a map represented as points, lines or polygons (areas). This Georeferenced information is associated with one or more attributes.
ATTRIBUTE
Descriptive data often associated to specific features through geographic information
contains descriptive data often associated to specific features through geographic
information contained in the attribute. An attribute can contain information, for example, the
estimated population of a Suco, where the name of the attribute could be shortened
POPEST for easy recognition of what the values of the attribute actually represent.
DATA VALUE
The data of a specific attribute e.g. representing the number of an estimated
the name of a city.
population or
ATTRIBUTE TABLE
Table displaying all the attributes of a specific feature and their associated values

VECTOR LAYER
Data layer representing points, lines and polygons on a map.
SHAPE FILE
File format used by GeoNode for uploading a vector layer. It is digital vector storage
Shapefile –format for storing geometric location and associated attribute information,
including the four file formats:
.shp – shape format; the feature geometry
.shx – shape index format; a positional index of the feature geometry to allow seeking
forwards and backwards quickly
.dbf – attribute format; column attributes for each shape
.prj - projection format; the coordinate system and projection information, a plain text file
describing the projection of the data
RASTER LAYER
Data layer comprised of either digital aerial photographs, imagery from satellites, digital
pictures, or even scanned maps. The layer consists of pixels organized into a grid where
each cell contains a value representing information (e.g. population).
STYLE A LAYER
Modify the appearance of a layer by using less advanced features (such as symbols and
colors) and more advanced features (such as setting rules for conditions and scales) to
visualize certain data attributes.

The toolbar just above the map is used to easily navigate between different extents and scales
(Figure 2-5).
GeoNode also allows the user to view a map in Google Earth with an embedded Google Earth
Viewer. You will need to install the Google Earth plug-in, which is available for download at Google’s
website or
Here: http://www.google.com/earth/explore/products/plugin.html.
Figu r e 2- 5: T ool ba r f or m ap nav i gat ion
The toolbar on the top-left side has used for editing and managing the map (Figure 2-6). Here you
may:
a. Save or Publish the map on a website by using Map (only for registered users),
b. Print the map by saving it in pdf-file format,
c. View feature attributes on a selected location on the map by using Identify,
d. View attribute table of a selected layer and search for specific values by using Query,
e. Measure a specific length or area on the map, and
f.
Edit the value of selected features (depending on permissions).

3. You will find various pre-set Base Maps in the panel on the left side of the page (Figure 2-8),
which can be altered depending on how you would like the base layer to be displayed.
4. The Overlays are the layers used for composing the map. By ticking the box on the left side
of a layer title, you can turn it on, or off, in order to either display it, or hide it, on the map.
The layers are displayed on the map according to their order in the panel list, where layers on
top have visual precedence in ascending order. To change the display order of the layers,
simply drag-and-drop them up or down. The toolbar symbols at the top allow you to Add
or Remove Layers, and change Layer Properties. The Style palette symbol is only active if
a user with the right permissions has signed in.

NOTE
To view detailed information of a specific layer, right-click on the layer in the panel and
choose Layer Info. A new tab in the web browser with all the information of the layer will
open without the user having to exit the Map Composer interface.
With Layer Properties, it is possible to adjust and save the display of that layer in the Map Composer
without actually changing the original style of the layer. This function is useful if e.g. you do not
have permissions to save or edit a layer but still would like to modify the appearance of a layer for a
specific map you are creating. To use Layer Properties select the layer and click on the wrench
symbol in the toolbar. Under the tab About, you can provide a title for the display of the layer as well
as a description. Under the Display tab user can modify the transparency of a layer by defining the
Opacity percentage, as well as constrain certain aspects of the layer by using Limit with filters and
Limit by scale.

It is possible to quickly navigate to the maps where the layer is being applied and by using
Create a map the current layer will automatically appear in a map for continuous map
creation. It is possible to extract the data of a vector layer in different file formats (KML,
GeoJson, Excel, CSV or Zipped Shapefile) as well as the data of a raster layer (GeoTIFF,
ArcGrid, KML, PNG or JPEG), by using the Orange button Download Layer at the top
Center. This is useful in case you would like to send data, or need to use data offline with
other GIS software such as QGIS or ArcGIS.
CREATE A MAP USING LAYER
GeoNode allows you to easily create a map using layers already saved into the platform. You can
choose between two simple procedures to create a map this way:
1. Find the layer you would like to use for the map either through a search or by clicking on Layers,
and then use the blue button Create a map In (Figure 2.11) the layer containing Bridge Details of
Timor-Leste). Your chosen layer will automatically appear in a new map and as an overlay in the
side panel.

Permissions
Permissions determine who can view, download, edit and manage layers, maps and
documents. It is important to understand the differences between these settings since
neglecting specifying permissions can result in giving unintentional access to layers/maps.
The following settings are available:
Who can view and download this Layer/Map/Data?
• Anyone: allows anyone to access the data, including unregistered users.
• Any registered users: only users with a GeoNode account can access data.
• Only users who can edit: limits access to users specified in below setting. Who can edit
this data?
• Any registered users: allows any user to edit, replace or remove your data.
• Only the following users: limits editing rights to the users you specify (in addition to the
owner of the layer/map).
Who can manage and edit this Layer/Map/Data?
• Limits managing permissions to specified users. They become the only users able to set
the permissions of the layer/map. The user uploading a layer is by default the owner of that
layer with full managing permissions.
To ensure correct permissions are selected, adjust them before uploading new layers,
creating maps or uploading documents (Figure 4-1). You can change these settings later in
the Layer View, Map View and Document View interfaces, by using the red Edit
Layer/Edit Map/Edit Document button and Edit (Map) Permissions.

Upload Layers and Documents
5.1 Upload Layers
In GeoNode, it is possible to upload your Layer to the system, allowing you to create raster
and vector layers that can be shared or used to create maps.
First click on Layer button on home page, then by clicking Blue color Upload Layers button
Figure 5-1: Upload layer interface to select the data you would like to upload, simply
1. drag-and-drop your files onto the gray area or
2.
Browse and select the files from your file system.
The files will appear below the drag-and-drop area, and the system will automatically specify
the file format as Shape files or GeoTIFF (Figure 5-1). In case a required file is missing (for
shape files) you will be requested to add the file before you can proceed uploading.
On the Explore Layers interface by using Upload Layers, user can upload the Layer
Figu r e 5- 1: Upl oa d la ye r int e rf ac e
NOTE
GeoNode supports uploading of vector layers in Shapefile format (comprised of four files
with the extensions: .shp, .prj, .shx, .dbf) and raster layers in GeoTIFF format. The system
also supports optional pre-defined visualization styles in SLD format for both layers formats,
as well as pre-defined metadata in XML format for raster layers
Before starting the upload, the Permissions of the layer needs to be specified on the right
side of the gray drag-and-drop area (see previous section for details on permissions). By
clicking on Upload Files the process of uploading the files will start

After a successful upload, three options on how to continue managing the data will appear
(Figure 5-4):
LAYER INFO
Allows you to access the Layer View interface from which you can proceed to edit the layer,
including changing Permissions for your layer after upload.
EDIT METADATA
Takes you to an interface where detailed information on the layer should be provided. In the
section below, this function will be explained in more detail.
MANAGE STYLES
Allows user to select a predefined appearance for your layer amongst the styles already
created. This complex function should be reserved for administrators or very advanced
users.
Figu r e 5- 4: Af t er s uc ce s sfu l u plo ad – th r e e o ptio ns
METADATA
By providing additional information about the layer after it has been uploaded, you are able
to specify the data and make the layer more accessible to other users.
Providing metadata thereby helps contextualize layers and aims to increase the overall user
experience of the GeoNode community.
After a layer has been uploaded, or if you are in the Layer View interface, you can use Edit
Metadata to start providing more information about your layer. Some fields are automatically
filled in, but most are left empty for you to provide information (Figure 5-1-1-1)

• Title: Provide an explanatory name for your layer. The name should not follow the naming
conventions for data files but instead correctly reflect main aspects of the data. Start the title
with a geographical specification (country, region, or “Global”).
• Abstract: Provide a brief description for your layer. This text will appear together with your
layer e.g. in the search results.
• Keywords region: Select one or more countries that the layer represents.
• Keywords: Specify keywords for your layer to appear in search results.
• Supplemental information: Specify what the attributes represent by giving a brief
description of each attribute. This information is the only explanation other users will have to
understand the attribute short names and therefore it is critical that a description is provided.
The supplemental information will appear under your layer in the Layer View interface when
you click Show/Hide.
• Attributes: Provide further descriptions of all the attribute short names or change the
display order of the attributes.
Click Update at the bottom to save and enter the Layer View interface.

Style a Layers and Create Rules
It is quite difficult to style a layer and create rules. It is helpful for advance level user as if
Admin to display certain Data attributes of a layer it is possible to modify the appearance of
the layer, i.e. style the layer, in a variety of ways. This may include control over the colors of
lines (e.g. roads) or areas (e.g. regions), as well as the display of labels (e.g. names of
cities). It is also possible to use rules to support complex symbolization schemes based on
database and scale conditions.
Below are a few different ways to begin editing a style in GeoNode:
1. Directly after uploading a data layer by clicking on Layer Info to view the layer and
then using the red button Edit Layer and Edit Styles. (Figure 6-1)
2. In the Layer View interface by using the blue button Edit Layer and Edit Style, or
directly on the Layer Styles palette symbol (Figure 6-1).
3. In the Map Composer interface by using the palette symbol (Figure 6-1)
Figu r e 6- 1: d ef au lt m ode w ith d iff er ent to ols fo r ed iti ng st yl e s
Following any of the above procedures, a pop-up window will allow you to choose Style and
set Rules (Figure 6-2). Here you can Add, Remove, Duplicate or Edit rules.

Figu r e 6- 2: L a ye r st yl es po p - up w indow – set rul e s
To create a color scheme for the rule select it and use the Edit symbol. Another pop-up
window will appear where you find three tabs called
a. Basic
b.
Labels and
c. Advanced
That contains options for defining the rule. Aspects of the rule that you set under one of the
tabs are cumulative for the entire rule. This means that you can create a rule by setting the
color in the Basic tab and then a database condition to control the display of that color in the
Advanced tab.
1. In the Basic tab it is possible to change the following styling options:
• Name of the rule
• Symbol to represent a feature and its size and rotation
• Color and opacity (transparency) of a feature
• Style, color, width and opacity of the line of the feature.
Figure 6-4 shows the default style of the Basic tab. Figure 6-3-b provides an example of
how certain aspects of a rule can be changed, such as symbol, color and stroke.

2. In the Labels tab it is possible to do the following:
• Select a field to use as content for your labels

Along Dili-Ainaro and Linked Road Corridors Project
• Choose a font type, size and style for the Label
• Choose the color for the Label as well as the opacity
• Choose a halo (background color) including color, size, and opacity
The user must know what the short name of a particular attribute represent in order to set
the label values. In Figure 6-5, the Label Feature box has been ticked and the Label values
specified to “Route_1”. In the example below, this short name represents the names of the
locations of the warehouses that need to be displayed in the layer.

3. In the Advanced tab it is possible to do the following:
• Limit the visualization of what has been defined in the Basic and Label tabs in terms of
one or more database conditions. It is also possible to set multiple groups of conditions.

• Limit the visualization of what has been defined in the Basic and Label tabs in terms of
minimum and maximum scale display.
Figure 6-5 shows how the box Limit by condition has been ticked, allowing you to specify
conditions for when aspects of the other two tabs should be displayed in the layer. In this
example, the specified condition will result in only displaying Bridge Location with
Replacement cost above 50000 in the layer.
In order to limit the conditions of how the values are displayed the user must know what the
name of a particular attribute represents. Moreover, the range of values that exists for that
attribute also has to be known in order to create a meaningful display of the data (which will
be visible in a legend).
Figu r e 6- 6: Adv an ce d ta b – mod ifi ed
Multiple rules in the same layer can be used to create a visual distinction between different
values or ranges of values. The different rules and the associated color schemes will be
represented in a legend for an appealing visual reference. Use the Add symbol to create
new rules, or Duplicate existing rules before editing.

In Figure 6-6, another rule has been customized after duplicating the first rule in order to
visualize bridge location with replacement cost less than 50000 in green. In addition, the
names of the rules in the Basic tab have been changed to better visualize the color scheme
in the legend.

NOTE
By editing data in the Map Composer interface, you are not just changing the appearance of
all the maps using the layer, but more importantly, you are editing the original dataset. If
these changes are due to version updates of the layer, this should be noted in the metadata
in order to avoid confusion for other users. In the Metadata interface, adjust settings for e.g.
Date Type, Edition and Maintenance Frequency.
