Introduction
What is ELF? ELF is a European project From March 2013 to October 2016 Around 30 partners NMCAs and EuroGeographics Technology providers Universities Application developers ….. Co-funded by European Commission and the consortium partners Main objective: single access point to harmonised data and services from NMCAs ELF partners (data providers)

The ELF objectives Supply harmonised, INSPIRE-based data on Europe Implementation phase (2013 – 2015) Supply harmonised, INSPIRE-based data on Europe Supply view, download, geocoding services on this data Supply an infrastructure enabling easy access to ELF data and data services d’ELF Oskari Arc GIS on line Develop applications using the ELF platform Exploitation phase (2015- 2016)
Technical achievements
Data specification ELF data specifications are INSPIRE based What is the added value of ELF specification compared to INSPIRE ones? Extensions Keep the additional information of EBM/ ERM/EGM Clarification about levels of detail ELF
Data specification: levels of detail (LoD) INSPIRE approach : The directive requires consistency between LoD Data model is the same for all LoDs Information about LoD is given by metadata element: MD_Resolution 2K 20K 25K 1M 10K 5K 50K 100K 250K 1 K 200 K 2,5 K Not easy for users to identify which data sets may be combined together
Data specification: levels of detail ELF approach: 5 levels of detail 2K 20K 2,5K 1 K 10K 50K 250K 1M 5K 25K Master level 0 To 5K Master level 1 5K – 25K Master level 2 25K- 100K Regional level 100K -500K Global level 0 500K- 1M
Data specification: levels of detail Some themes are relevant only for some levels of detail Theme MASTER LoD0 Master LoD1/2 REGIONAL GLOBAL Cadastral Parcels (CP) x Addresses (AD) Buildings (BU) Administrative Units (AU) Geographical Names (GN) Transport Networks (TN) Hydrography (HY) Land Cover (LC) Elevation (EL)
Data transformation First step in ELF project Transform data from (heterogeneous) national data specifications to the common ELF data specifications Common data model Common Coordinate Reference System(s) Transformation method is up to each NMCA Possible help from technology providers Benefit for users: ELF pushes NMCAs to provide INSPIRE-based data before the official deadline
Single access point (download) The scenario to be avoided NMCA National WFS request NMCA National WFS answer NMCA National WFS A user wanting data on several countries should not be obliged to access several services.
Single access point (download) The ELF scenario NMCA National WFS Cascaded Service (WFS) request NMCA National WFS answer NMCA National WFS The user is offered a single access point through the cascaded service.
Single access point (download) Database of international boundaries Step1: identify the countries concerned by the request Cascaded service: distribute request Cascaded Service (WFS) NMCA National WFS Step 2: distribute the request to the concerned national WFS National WFS NMCA Request (feature type, bounding box) National WFS NMCA (X1, Y1) (X4, Y4) National WFS NMCA (X2, Y2) (X3, Y3) National WFS NMCA
Single access point (download) Cascaded service: aggregate answers Step 1 : each national WFS provides data set according to the request NMCA National WFS National WFS NMCA Cascaded Service National WFS NMCA Step 2 :the cascaded service aggregates the national answers in one single feature collection National WFS NMCA National WFS NMCA
Set of centralised data sets GeoLocator Request (indirect location) The indirect location may be a geographical name, an administrative unit, an address or a parcel code. Direct geocoding GeoLocator Answer (direct location) The direct location will be a point defined by its coordinates (X1, Y1). GN AU AD CP Set of centralised data sets
GeoLocator GeoLocator offers: Using data from: Direct geocoding Reverse geocoding Using data from: Previous project EGN (EuroGeoNames) To be replaced by INSPIRE data on themes Address, Administrative Units, GeographicalNames and CadastralParcels
Topographic BaseMap BaseMap is a pyramid of digital maps displaying ELF based data, at different levels of zoom Content : themes EL, AU, BU, LC, HY, TN and GN Zoom levels from 2K (street names) to 40M (whole Europe) Available as WMTS To be used for consultation or as background map
Portrayal rules: theme Transport (Road) Topographic BaseMap Portrayal rules: theme Transport (Road) Example in urban area, with street names (4,5K)
Administrative BaseMap Based on EBM data From 40M to 170K WMS service
view search identify ELF Cadastre Involved themes: WMS of data providers managed by cascade tools => vision of territory. Involved themes: Cadastral Parcels Administrative Units Addresses Buildings Search Services to locate Cadastral parcels by its identifier or by its address (by use of GeoLocator) search GetFeatureInfo to identify cadastral parcel and to obtain all the associated information from the national cadastral agencies. identify
ELF Cadastre use cases Complement BaseMap BaseMap : for LoD1 to Global (40 M to 2K) ELF Cadastre : for LoD0 (10K to 1) Users may combine in client applications the BaseMap with the layers of ELF Cadastre 12 By adding addresses AB56 By adding cadastral parcels
A key attribute to make link with land registration system ELF Cadastre use cases Complement EULIS ELF Cadastre : provide the geographic information EULIS : provide the legal, fiscal information Owners First name Last name Birth date … Jean Martin 12/04/1980 EULIS ELF A key attribute to make link with land registration system
Application for Health Statistics CASPER To link health statistics data to AU/SU Eurostat health statistics data (> 300 available data tables). Spatial framework data (EuroBoundaryMap) Use the OGC table joining standard Eurostat’s health statistics (>300 tables) CASPER 31 May, 2019
CASPER Client – a portrait of Europe health Potential users: Policy makers Journalists Academic researchers Health officials Health insurance providers General public 31 May, 2019
Business Applications The aim is to have at least 30 applications based on ELF services and data 4 applications in ELF (including CASPER) => find external application developers ELF Awareness Tour ELF Awards 31 May, 2019
ELF ambitions
ELF after the ELF project European Location Framework is not just a project Sustainable platform that won’t stop on October 2016 Strong involvement of EuroGeographics May be, a follow-up project ?
Get more data and services European coverage on topographic and cadastral data themes Welcome thematic data (e.g. statistics) : The European Location Framework for Geostatistics (Mick Cory) – 11/11/2015 morning 2013 2016 Objective - 2020
