WHAT IS OSKARI? An Open Source package for easily building varied web mapping applications With Oskari you can –compose application by selecting functionalities from existing components –set up advanced web-based tools, such as decisionmaking support services –create embedded maps –control embedded map from parent document –connect to standard OGC data sources –add your own data or dataset

Proprietary interface Standard interface Oskari Browser-based Applications with Maps Raster Statistical data MetadataGMLELF data INSPIRE data SAAS RPC Embedded Maps

EXAMPLE IMPLEMENTATION National Geoportal of Finland

EMBEDDED MAPS Define embedded map clients in just a few minutes to be used as SAAS in an iframe on other websites Easy to change - Add/remove functionality or map layers Interact with the embedding website using RPC protocol More about Oskari Embedded Maps: Friday Grand Ballroom Map publishing with or without programming skills – Timo Aarnio

OSKARI FEATURES Support for multiple languages: –Through European Location Framework Project, the basic functionality can be found in most European languages. Works with all major browsers: –IE9+, latest versions of Firefox, Chrome and Safari The interface should work with modern tablets and smartphones –Currently there is no separate mobile/tablet-optimized version Role-based user management –Users belonging to different roles can be given access to specific functionality

OSKARI ARCHITECTURE Oskari Backend

OSKARI FRONTEND Oskari UI is implemented as a collection of reusable bundles Bundle is a component that offers functionality for an application Examples of bundles: –Analysis –Heatmap –Printout –Search Applications are formed by starting one or more bundles which create the application Bundles are loosely coupled – they communicate with requests and events

OSKARI BACKEND Built with Java - packaged as Maven modules Server-side includes different webapps: –oskari-map, transport & printout Geoserver is used to store/serve user content: –Analyse (using WPS) –my places –userlayer (Shapefile etc import) User management: –Database/SAML based –Spring security can be extended for Oauth etc Secure proxy for maplayers (role-based permissions) Easy to extend/customize/add: –Custom AJAX Endpoints (=Action Routes in Oskari) –Search implementations –Custom login/user handling hook

WHY USE OSKARI? –Open Source and freely exploitable by anyone interested –Enables controlled extensibility –Ready-made components for creating extensive map-based softwares –Connect to standard OGC data sources –Provides framework for modular development –Tools for minifying code

OSKARI DEVELOPMENT OSKARI NETWORK Developed originally by National Land Survey of Finland Today multiple parties have joined Oskari development Oskari Network was established 2014 to develop Oskari in co- operation More about Oskari Network: Friday Grand Ballroom How to build a succesful co-operation around your FOSS software - case Oskari – Jani Kylmäaho

HOW TO START DEVELOPING OSKARI? Requirements: –JDK 1.7+ pre-installed and database available Download Oskari easily as one zip-file: – Modify database properties to match your environment and start the server Start developing your own web mapping application! Documentation:
