The document discusses options for implementing a free and open-source (FOSS) geoportal using different software. It describes spatial data infrastructure (SDI) and components of a geoportal like geospatial servers, metadata catalogs, and clients. Popular FOSS options are presented for each component, including GeoServer, GeoNetwork, GeoNode, and others. The document compares the pros and cons of using GeoNetwork and GeoNode specifically. It also provides examples of implementing FOSS geoportals for different projects and customizing them.

Spatial Data Infrastructure (SDI)
The SDI is a set of technologies, policies and
institutional arrangement that facilitate
availability and access to spatial data. The SDI
also provides a basis for spatial data discovery,
evaluation, data sharing and application for
users and providers.

In order to use the harvesting module of geonetwork in a proper way it’s strongly suggested
to install the Catalog Services for the Web (CSW) plugin on GeoServer that allows the
retrieval of all the available information of each layer on the system and perform queries:
Request all layers:
http://localhost:8080/geoserver/csw?service=CSW&version=2.0.2&request=GetRecords&typeNames=gmd:MD_Metadata&res
ultType=results&elementSetName=full&outputSchema=http://www.isotc211.org/2005/gmd
Request a particular layer by ID…:
http://localhost:8080/geoserver/csw?service=CSW&version=2.0.2&request=GetRecordById&elementsetname=summary&id
=CoverageInfoImpl--4a9eec43:132d48aac79:-8000&typeNames=gmd:MD_Metadata&resultType=results&elementSetNam
e=full&outputSchema=http://www.isotc211.org/2005/gmd
…or use a filter to retrieve it by Title:
http://localhost:8080/geoserver/csw?service=CSW&version=2.0.2&request=GetRecords&typeNames=gmd:MD_Metadata&re
sultType=results&elementSetName=full&outputSchema=http://www.isotc211.org/2005/gmd&constraint=Title=%27mosaic%

Pros in using GeoNetwork:
● It can handle many different types of metadata standards.
● Easy to install, setup and customize.
● It can easily handle time series metadata.
Cons in using GeoNetwork:
● It is a geocatalog and not a geoportal.
● Not possible to upload geospatial data through the interface.
● Not possible to create, customise and export maps.

Pros in using GeoNode:
● Uploading geospatial data through a user friendly interface both Raster and Vector.
● Style data on the fly .
● Creating custom maps using the layers available on the system.
● Performing queries on the fly over the layers.
Cons in using GeoNode:
● More work is required in the installation/configuration process.
● Programming skills are required to implement additional functionalities.
● Upgrading to a new version might be quite tricky.
