Executive summary
This product specification describes the product “ELF Cadastral Index Map”.
ELF Cadastral Index Map is a view service that provides a simplified and harmonised view of footprints of cadastral parcels geometry combined with other basic information as administrative units, addresses and buildings for pan-European use.
It will permit also to identify the features and to obtain both
• the national cadastral reference of the cadastral parcel, that gives users the opportunity to get more information through the cadastral national services,
• and the complete address of the cadastral parcel or building.
This deliverable provides: A narrative description of the ELF Cadastral Index Map service, an example of the data content and basic guidelines for implementation.
The main chapter is the portrayal one that defines the ELF Cadastral Index Map style taking into account the INSPIRE default portrayal for themes CP, BU, AD and AU, the combination of all of them and the range of scales of ELF Cadastral Index Map.
This specification contains also information about data capture, data quality and delivery.

1 Scope This document defines a harmonised product specification for ELF Cadastral Index Map.
ELF Cadastral Index Map, as a view service displaying reference data, will permit ELF to provide a view service combining several very useful large scale information as Cadastral Parcels (CP), Buildings (BU), Addresses (AD) and Administrative Units (AU).
The possibility of combining these topics in ELF Cadastral Index Map at European level is important since addresses are the main way of search and location of the geographical objects by the European citizens. The cadastral parcel and the representation of buildings are very useful tools for the application of many policies in which property distribution or other cadastral information is quite necessary.
The scope of this document is therefore to define the specifications that will permit, through ELF cascading service, to access the WMS of the different data provider of these four themes, to combine them and to show a continuous map for all Europe.
ELF Cadastral Index Map is not one single map layer. It is composed by theme-specific map layers as it is detailed in this document. The ELF Cadastral Index Map includes map layers organised theme-wise. Each theme has its layers and the styles are defined for each layer. This will also make the ELF Cadastral Index Map visualization more flexible, as the layers can be individually switched on and off. By still keeping the combined layers included we ensure the most simple possible inclusion of the ELF cadastral information in various client environments.
The national ELF services shall support the GetFeatureInfo functionality for Cadastral Parcel. This will allow identifying the features of the layer and obtaining the national reference that provides a way to access more complete national information, taking into account the differences of the legal regulations of such a data in the different Member States.
The national ELF services shall also support the GetFeatureInfo functionality for Addresses. This will allow to get the complete address for an address point in the map.

Description
ELF Cadastral Index Map provides a simplified and harmonised view of information such as cadastral parcels geometry, addresses, buildings and the administrative units for pan-European use in land administration domain such as agriculture, spatial planning, environmental, infrastructure and utilities management, public land management, risk and security services, socioeconomic data and cartography in general.
ELF Cadastral Index Map aims to provide official cadastral reference data of the partner countries.
The ELF Cadastral Index Map includes map layers organised theme-wise. Each theme has its layers and the styles are defined for each layer.
ELF Cadastral Index Map will provide INSPIRE Cadastral Parcels layer with their features (core) from ELF data as a common minimum among all the existing cadastral systems, to be used only as locators of geo-information.
Data providers will offer in a harmonized way the layers that represent the main feature: cadastral parcel, providing: geometry, inspireId, areaValue, label, referencePoint, temporal attributes and national cadastral reference. Some countries can provide also layers for any of the 3 additional feature types to fit with national specificities (conditional feature types) such a Cadastral Zoning, Basic Property Unit and Boundaries.
ELF Cadastral Index Map will also provide the layers with representation of INSPIRE features for Addresses, Administrative Units and Buildings of those agencies that provide them in ELF.
Each country may have different data producers for the 4 themes that constitute the product ELF Cadastral Index Map (AU, CP, AD and BU), different agencies, and even different territorial areas. ELF Cadastral Index Map has to contemplate all these singularities.
Spatial data structure
The reference data is defined in one data specification to maintain the necessary relationship between spatial data themes to achieve cross-theme consistency.
Spatial Extent
According to the directive INSPIRE shall build upon infrastructures for spatial information established and operated by the Member States. Subsequently, the spatial extent of the ELF should take into account the spatial extent defined at national level.
ELF targets to cover geographical Europe based on adoption by European NMCAs. It can be also utilized outside of Europe, e.g. for the respective overseas territories of European countries.
Level of Detail
The scale range can vary from 1:100 to 1:10.000 depending of the NMCA data provider. It is included in ELF Master LoD0 and LoD1.
Purpose
In the ELF context, cadastral parcels will be mainly used as locators for geoinformation.
National cadastral registers generally contain much more data and users and other 3rd parties will be able through ELF Cadastral Index Map to identify the objects and obtain the national reference. With this national reference they will have the opportunity to obtain other valuable information through the national services.
ELF opens the door to the national cadastres and via cadastral reference, as key attribute, may allow to find other information as owners, values, uses etc.
The European Location Framework (ELF)
E.L.F. Deliverable D2.8 8 Version 2.1, 13th April 2016
It addresses domains such as agriculture, spatial planning, environment, infrastructure and utilities management, public land management, risk management and socio-economic analysis.
The ELF Cadastral Index Map will meet the requirements of the main ELF use cases that need the cadastral index map , the representation of the buildings or the addresses of the properties as geolocators of human activities; for example:
• WP7 as insurance company, Emergency Mapping use case
• Insurance risk assessment application
• Companies that utilize the ELF base map together with various reference data themes and hazard data layers
• E-justice Portal where ELF Cadastral Index Map can provide the geographic information that is needed to access to the legal information.
• European Land Information Service (EULIS)
• Complement the ELF topographic BaseMap: The ELF topographic BaseMap is a pyramid of numeric maps at various zoom levels (from 2K to 40M), displaying data from themes Land Cover, TransportNetwork, AdministrativeUnits, Hydrography, GeographicalNames, Buildings and Elevation. Many users may be interested by adding the ELF Cadastral Index Map layers (mainly CP and AD) on the background BaseMap (e.g. at zoom level 2K) that shows the streets and their names
Data Sources
The primary sources used for ELF Cadastral Index Map are the national data collections of the NMCAs at national level of detail corresponding to ELF Master LoD0 and/or LoD1 [ELF D2.10].

4 Data Product identification These Technical Guidelines are identified by the following URI: http://elfproject.eu/documentation/specification/D2.8_ELF_cadastre_
NOTE: ISO 19131 suggests further identification information to be included in this section, e.g. the title, abstract or spatial representation type. The proposed items are already described in the document metadata, executive summary, overview description (section 2) and descriptions of the application schemas (section 5). In order to avoid redundancy, they are not repeated here.
5 Data content and structure The concept of ELF Cadastral Index Map describes a reference framework at European level. This framework consists of the representation of the official Cadastral Parcel, Addresses, Buildings and also Administrative Units when needed, compliant with the ELF data specifications requirements, from existing NMCA databases. ELF Cadastral Index Map specification will permit at European Level to view the cadastral parcel layer combined with addresses layer, buildings layer and administrative units layer. The cadastral parcel is the basic feature of ELF Cadastral Index Map which should be present. As data comes from different INSPIRE themes and could be provided by different NMCA’s; occasionally some of them may be missing.
Figure 1 – ELF Cadastral Index Map Framework
The ELF Cadastral Index Map includes map layers organised theme-wise. Each theme has its layers and the styles are defined for each layer. The main ELF Cadastral Index Map features that are represented in the layers are:
• Cadastral Parcel: This feature type has the same concept as defined in the ELF CP data specification. This feature has the same attributes and constraints as defined in the ELF CP data specification. ELF Cadastral Index Map view service will display, as basic component, the geometry of cadastral parcel.
• Address: This feature type has the same concept as defined in the ELF AD data specification.
E.L.F. Deliverable D2.8 11 Version 2.1, 13th April 2016
This feature has the same attributes and constraints as defined in the ELF AD data specification. ELF Cadastral Index Map view service will display only the address positions of access entrance or locator designator
• Building: This feature type has the same concept as defined in the INSPIRE BU data specification. This feature has the same attributes and constraints as defined in the INSPIRE BU data specification. Buildingpart: ELF Cadastral Index Map view service will display both building and building parts (if any)
• AdministrativeUnit: This feature type has the same concept as defined in the ELF AU data specification. This feature has the same attributes and constraints as defined in the ELF AU data specification. ELF Cadastral Index Map view service will display the geometry of administrative units
Optional features:
• Cadastral Zoning: This component represents intermediary areas in order to divide the national territory into cadastral parcels. Cadastral parcels can be municipality, section, parish, district, block etc. This feature type has the same concept as defined in the ELF CP data specification. This feature has the same attributes and constraints as defined in the ELF CP data specification.
• Cadastral Boundaries: • Basic Property Units
The main layer in ELF Cadastral Index Map is the CP CadastralParcel and is the only one obligatory. It is present in all the scales of ELF Cadastral Index Map from 1:100 to 1:10.000 and must be available for consultation and searchable.
It is necessary to harmonize it (define a uniform style) so that all national services return data in the same output format. And it is very important to provide the link to access further cadastral information (owner, use etc.) that are in the national system for the cadastral parcel selected. This is realised by providing the national cadastral reference.
Therefore GetFeatureInfo (GFI) for cadastral parcel must return at least the national cadastral reference and if possible a hyperlink (URL) to access the national system.
In the same way it is important to be able to identify each address that is displayed in the ELF Cadastral Index Map with the GetFeatureInfo for address.
This means two GFI-capable layers are expected: Cadastral Parcels and Addresses. These two layers can be provided either by one single WMS instance or by two separate WMS instances. The specific motivation is stressing the possibility for having two separate WMSs is that Cadastral Parcel and Address information might be provided by two different organisations.
Recommendation 1 GetFeatureInfo response for the layer CadastralParcel shall be in the form of XML or

This way the ELF services would be able via cascading service itself to show the GetFeatureInfo response in a harmonized way.
Recommendation 3 Get feature picking will be inside the cadastral parcel.
6 Reference Systems In general, the INSPIRE requirements for reference systems (Datum, Coordinate reference systems, Display, Identifiers for coordinate reference systems and Temporal reference systems) are valid for ELF Cadastral Index Map. ELF view services are provided with the following two CRS in order to allow combination with different ELF themes or products (such as topographic Basemap) as well as with other external data:
• Web Mercator (WGS 84 / Popular Visualization Pseudo-Mercator): http://www.opengis.net/def/crs/EPSG/0/3857
• Lambert Azimuthal Equal area (2D LAEA projection in ETRS89 on GRS80): http://www.opengis.net/def/crs/EPSG/0/3035
7 Data Quality The objective of ELF Cadastral Index Map is to provide pan-European view service based on data of high quality according the rules of INSPIRE and ELF data specifications for the themes that are part of ELF Cadastral Index Map. The CP layer, is those provided by NMCAs and will contain the authoritative information that shows legal or official boundaries that cannot be subjected to a process of cross-border edge-matching; therefore it may show cadastral gaps and overlaps.
7.1 Update frequency National contributions to ELF Cadastral Index Map are maintained and updated as deemed necessary by the data provider. The maintenance and update frequency should adhere to national update regime for each ELF theme. Update frequency is a key for cadastral data. NMCA should put efforts to offer up-to-date content.
Recommendation 4 If it is not possible to provide updates on a daily basis, it is recommended to provide data
updated within a month of period as maximum.
7.2 Quality characteristics of the services ELF Cadastral Index Map must fulfil INSPIRE requirements for view services. ELF Service Level Agreements are managed centrally through Data Provider Agreements (DPA).
E.L.F. Deliverable D2.8 14 Version 2.1, 13th April 2016
8 Metadata Metadata are fundamental elements needed to discover; access and use geographic data products. ELF Cadastral Index Map will follow the general metadata guidelines of the ELF project as stated in Annex B of deliverable [ELF D2.3.6] and the ELF data specification [8]. For delivery of positional accuracy there is a triple choice: statement related to the whole dataset or, as mentioned before, an attribute attached to the cadastral zonings or the cadastral boundaries.
8.1 National specificities Metadata at dataset level must be provided with the data and also has to contain information about the lineage, i.e. condition of creation and transformation of data. This element provides information on the remaining national specificities that may be worth noting after applying the transformation to ELF.
Recommendation 5 The template provided as part of deliverable “D2.3.6_Quality_AnnexC.doc” [ELF D2.3.6]
should be used for reporting national specifics as part of the lineage information.
9 Delivery
9.1 Delivery updates
The view service should be updated according to the update frequency of the data (see 7.1)..
9.2 Delivery medium ELF Cadastral Index Map is made available through services on the ELF platform www.locationframework.eu by national view services. These national services shall:
• allow cascading based on ELF/INSPIRE compliant national theme-based WMS CP, AU, BU, AD,
• support ELF SLD or provide WMS with ELS styles,
• support GetFeatureInfo functionality that will allow identifying the features. The WMS should at least support the OGC WMS Implementation specification version 1.1.1

11 Portrayal
11.1 Layers The ELF Cadastral Index Map combines the four themes and, in function of scale, and displays some or all of them. Different styles are defined for each range of scales. The representation of the ELF Cadastral Index Map is based on INSPIRE data specifications of each of the layers that constitute the product (AU, CP, AD, BU). The layer names are used as specified in INSPIRE:
In case that there are buildings or buildings parts below ground, the building is represented by over ground part.
Addresses require a representation different from the one defined in the specifications of INSPIRE. It is much clearer to represent addresses with the locator designator, than as a square as defined in the default representation. The identification of the address associated with the plot or the building is more important than display all complete addresses in the WMS.
Address is displayed by the locator designator in the access entrance as a black text and it is recommended to locate it in the access (portal) of the building or parcel and not in the centroid of the parcel since it would overlap the parcel label. The scales of visualization of ELF Cadastral Index Map range from scale 1:100 to 1:10.000. Such a range of scales makes representation difficult: both,
• when text labels are represented at smaller scales with a fixed size of text, • or when there is a high density of elements, by the degree of detail that produces overlapping of
texts, which prevents readability. For this reason ELF defines the object to be represented in each range of scales and defines the size of the text new specific proper representation styles have been defined for the use of this ELF Cadastral Index Map product.
Each of the themes that constitute the ELF Cadastral Index Map product can belong to different organisms within a geographical area, or even can be different WMS services for each item within the same organism. Therefore the view of ELF Cadastral Index Map has to contemplate these singularities in the services of cascade and it is necessary to define a symbology for each item and a hierarchy of scales that must be accorded with representation order.
Each Layer is represented with an ELF style. The characteristics of each style are shown in chapter 11.2
• CP.CadastralParcel is represented with CP.CadastralParcel.ELFCadastre • CP.CadastralZoning is represented with CP.CadastralZoning.ELFCadastre • AD.Address is represented with AD.Address.Number.ELFCadastre • AU.Administrative Unitis represented with AU.AdministrativeUnit.ELFCadastre • BU.Building is represented with BU.Building.ELFCadastre • BU.BuildingPart is represented with BU.BuildingPart.ELFCadastre

Table 3 – ELF styles according to scale range
As it is indicated in the portrayal chapter the styles for the layer cadastral parcel are defined in a way that it is possible to display:
• for scales 1: 2.000 to 1:10. 000 the boundaries of the Cadastral parcel s without to display labels
• and for scales 1:100 to 1:2000 boundaries plus labels
Equally, for the Administrative units layer the symbology changes for each scale range.
Recommendation 6 It is important to keep this order for drawing the layers.
Recommendation 7 It is recommended to use INSPIRE standardized layer names, if not, a mapping table
between the layer names of the national service and INSPIRE standardized layer names should be included.

It is important to follow the order of representation.
At 1:2.000 the first layer to be display is BU.Building that it is represented with BU.Building.ELFCadastre. It is a layer of solid fills in the interior of the buildings, the base could be transparent to be able to view it combined with other information or with an orthoimage. The proposed symbology for the outline of the buildings is a red line and the interior in a very pale red. The building parts only will be represented with a transparent background and a thin line also in red.
Cadastral parcels layer is also represented transparent with labels displayed as text. ELF Cadastral Index Map doesn’t use the default style CP.CadastralParcel.LabelOnReferencePoint defined in portrayal of specifications of CP because the size of the text of the label is a too large and sometimes the drawing is not readable. For this reason the CPCadastralParcel.ELFCadastre style has a smaller text size.
ELF changes also AD.Address.Default style of 6 pixel square with black border (default style of INSPIRE address) by display only the value from the LocatorDesignatorTypeValue. The address then will be displayed by locator designator as a black text.
Recommendation 8 Locate the value from the LocatorDesignatorTypeValue in the access entrance of the
building or parcel and not in the centroid of the parcel since it overlap the parcel label.
Recommendation 9 Do not display long text because it will paste the map and the value will be anyway
completed displayed in the GetFeatureInfo .
For the other intervals of scales up to 1:10.000 the only change will be the number of layers that are represented.
