GeoServer used in fun and interesting ways

Jody Garnett [email protected] @jodygarnett GeoCat Government Geographic Data publishing Andrea Aime Technical Lead [email protected] @geowolf GeoSolutions Innovative, robust, cost-effective solutions leveraging best-of-breed Open Source products. This presentation is brought to you by

GeoServer at a Glance Java Web Application to share and edit geospatial data. Publish data from any major spatial data source using open standards. Core Protocols WMS – maps WFS – vector WFS-T – editing WCS – coverage WMTS – tiles TMS – tiles WMS-C – tiles Extension/community protocols WPS – process CSW – search OGC API - json + rest standards OGC STAC - spatio-temporal asset catalogue

Powered by GeoServer GeoServer is a real open source, and OSGeo, success story in its own right. ● Open Source GPL License ● Established project first released in 2001! ● Diverse global development community ● Open Source Geospatial Foundation Project since 2011 ● … but that is not what this talk is about! GeoServer, as a component, powers a wide ecosystem of great solutions!

Before we start! The following GeoServer examples are here: ● Provide confidence ● Inspire with what is possible ● Illustrate flexibility We want you to feel safe in your technology choice: - GeoServer can take on very challenging situations! - Most situations are not so challenging! Be amazed not terrified please!

Product Integrations

Cloud Native GeoServer Gabriel (camptocamp) has a neat project - distribution of GeoServer components optimized for a cloud-first environment: ● spring-boot ● microservices ● Replaced a 60 nodes cluster Now an official GeoServer repository: https://github.com/geoserver/geoserver-cloud

GeoNode

GeoServer Enterprise (GeoCat) Commercial open-source distribution: ● Long-term-support ● Pre-configured WAR no need to install extensions Includes GeoCat Bridge publication from comfort of your Desktop GIS

GeoCat Live Spatial-Data-Infrastructure (SDI) in a box ● Catalogue services: GeoNetwork ● Mapping services: GeoServer ● Spatial database: PostGIS Includes GeoCat Bridge publication from comfort of your Desktop GIS Software-as-a-Service provided by a company dedicated to sustainable open source

https://www.georchestra.org/ geOrchestra provides independant and interoperable modules to build your own custom spatial data infrastructure: ● a data catalog based on GeoNetwork version 4.0.6, ● a map and feature server: GeoServer version 2.18.3, ● an advanced data access list manager: GeoFence, ● a map tiles server: GeoWebCache version 1.16.2, ● an advanced web map viewer with query, styling, editing functions, ● a data extractor to extract, reproject and download datasets from OGC services, ● a user, orgs & roles manager (“ldapadmin”), ● a module to display data usage statistics (“analytics”).

GeoServer Integrations

Cascading WMS for reprojecting / caching Ian Turton has helped use GeoServer to “supplement” less capable servers and clients. ● Added reprojection ● Caching for performance GeoServer WMS WMS WMS WMTS Web Clients
