Project Scope

Title - Strengthening multi-hazard risk assessment and early warning systems with applications of space

and geographic information systems in Pacific island countries

Scope of AIT - is to support Pacific Island countries in the use and dissemination of geospatial

information for disaster risk reduction (DRR) and post disaster activities

Objectives –

1. Implementing web-based geospatial data sharing platforms (geo-portals) with tools to manage and

share DRR data; Spatial and socio-economic data;

2. Improving capabilities for web-based mapping and geospatial data management (geo-database);

3. Conducting capacity building training programs on Remote Sensing, GIS and geospatial data sharing

frameworks for enhancing effectiveness of using these technologies for DRR

Project Scope

Need Assessment Survey • 14 PICs were contacted regarding the need assessment survey

• 11 feedbacks were received from 9 countries (highlighted in green)

Need Assessment Survey

Need Assessment Survey – Findings Web GIS

Are you currently using any Web GIS

platforms to share geospatial data?

Do you think it is useful for your

organization to have a Web GIS platforms

to share geospatial data?

What is GeoNode

• GeoNode is a geospatial content management system

• It’s a platform for the management and publication of geospatial data

• It provides an easy-to-use interface for the users to share data and create

interactive maps

• It can be considered as a geospatial data storage

• Vector Data (as Shapefiles)

• Raster Data (as GeoTIFFs)

• Meta Data

GeoNode Framework

GeoNode Framework

Building upon GIS open source projects

• GeoServer (Map Engine)

• PostgreSQL/PostGIS (Spatial Database)

• GeoNetwork (Meta Data)

• OpenLayers (Visualization)

• GeoExt (Tools)

• GeoWebCache (Caching)

GeoNode Framework

What GeoNode Offers

• Web based platform to keep and maintain GIS and Remote Sensing Data

(Geospatial Data)

• Create maps using available data

• Classify data in order to provide better visual interpretation

• Integrate with base maps such as Google map, Open Street map

• Advance users can access data available in GeoNode via desktop GIS

applications

GeoNode Framework

GeoNode Components

GeoNode Framework

Data Layers

• GeoNode makes it easy to upload and manage geospatial data

• Vector Data in ESRI Shape File Format

• Raster Data in GeoTIFF Format

• Data can be securely or publicly shared

• Restricted

• Public

• Share with particular users

• Data can be categorized

• Boundary, Health etc.

GeoNode Features

Maps

• GeoNode comes with helpful cartography tools for styling and composing

maps graphically

• GeoExplorer

• Create multi-layer interactive maps

• Integrating with Base Maps

• Google, Open Street etc.

GeoNode Features

Documents

GeoNode makes it easy to upload and manage documents

• PDF, JPG etc. by default

• Can be linked with data layers or maps

• Can be configured to allow any other formats

• Max document size can be set

GeoNode Features

Share and embed in web pages

GeoNode Features

Open with Google Earth

GeoNode Features

• Using GeoNode Interface

• By downloading KML file

Access via QGIS Desktop

• as Web Map Service (WMS)

• In image data format

• No attribute data is

transmitted

GeoNode Features

Access via QGIS Desktop

• as Web Feature Service (WFS)

• GML format

• Attribute data is transmitted

• All GIS operations are possible

GeoNode Features

Thematic Mapping • GeoNode Style Editor

• Good- if number of values in

classified field are less

• Using Third-party Tools

• Upload a SLD file together with

SHP file

• Tools such as Udig, AtlasStyler

can be used to generate SLD files

• Good- if number of values in

classified field are high

GeoNode Features

Connect with WMS Servers

• Any other GeoNode or WMS server can be permanently added to a given

GeoNode

GeoNode Features

Access through Database

• Via pgAdmin • Hence database can be used from other applications

GeoNode Features

QGIS via Database

• Via QGIS Desktop

• Attribute data available

GeoNode Features

Permissions

Permissions can be set for each

data layer, map and document

• who can view?

• who can download?

• who can edit metadata?

• who can edit?

• who can manage?
