Harmonizing geoinformation in Europe
• Concerns about 34 different types of data sets
• 27 different countries with 22 languages (and more
influence; e.g. Iceland, Norway and Switzerland are
also involved)
• Agreement on content during exchange, considering
consistency (within, but also) between:
• Themes
• Scales (levels of detail)
• Borders

Themes (annex I and II)

INSPIRE is a Framework Directive
Detailed technical provisions for the issues above will be laid
down in Implementing Rules, Once adopted, Implementing
Rules become European legislative acts and national law in
27 Member States and in some EFTA countries

General principles
INSPIRE lays down general rules to establish an infrastructure for spatial
information in Europe
- for the purposes of Community environmental policies and
- policies or activities which may have an impact on the environment
INSPIRE must be based on existing data
Harmonisation in INSPIRE must be done based on user requirements:
- pan-european use cases
- cross-border use cases
- linked with environment
Harmonisation has to be feasible and cost-benefits have to be analysed.

2. INSPIRE cadastral parcels
3. Discussion points
October 3, 2015

Stakeholders’ participation
Data specifications are developed by Thematic Working
Groups consisting of domain experts proposed by the
stakeholders (SDIC/LMO) and a facilitator and editor
nominated my the Commission
8 Thematic Working Groups on Annex I data
October 3, 2015
12
The context
1. Identification of main stakeholders:
• PCC
• EuroGeographics Expert Group on Cadastre
• FIG
• UN WPLA
• EURODIN (eContent + project)
2. Identification of relevant standards : LADM a new work
item proposal to ISO/TC 211 (by FIG)
3. Use a classification based on the one provided by WG-CPI
survey
• Land market
- Agriculture
• Environment
- Spatial planning
• Infrastructures
- Public administration
• Public safety
- Socio-economic analysis
October 3, 2015

Definition of cadastral parcel
• In the INSPIRE Directive:
• “areas defined by cadastral registers or equivalent”
• not very explicit (specially for MS having sub-parcels or
“over-parcels”)
• TWG CP explanation
• single part of earth surface with homogeneous rights
• 5 Core elements (WG-CPI): Geometry, Surface (area/size),
Identifier, Georeferencement, Temporal information, and
many optional ones…

Constraints in the model
• EndLifeSpanVersion
Natural language: If set, the date endLifespanVersion
must be later than beginLifespanVersion.
OCL: inv: self.endLifespanVersion
.isAfter(self.beginLifespanVersion)
• withTopology
Natural language: Attribute topology for cadastral parcel
(TP_Face) is mandatory if topology for cadastral
boundary (TP_Edge) is delivered.
OCL: inv: self.boundary -> notEmpty() and
self.topology -> notEmpty() implies
CadastralBoundary.topology -> notEmpty()
October 3, 2015
22
Some other points
two identifiers: INSPIRE and national
coordinates in ETRS89 on Eurasian plate, else ITRS
recommendation: no gaps & overlaps between parcels
CadastralIndexSet: ‘below’ admin units until municip
rights and owners outside the scope
only linear interpolation (no circular arcs)
portrayal for 2 layers with default (each 2 versions):
• parcel outline black 1 pixel, label Arial 10 black
• index set outline black 2 pixels, label Arial 20 black
• encoding GML 3.2.1 (ISO 19136:2007)

27
Attention points during testing
• ETRS89 coordinate transformation (from RD source):
• Accuracy
• Data valid after conversion; e.g. no intersections
• be careful with arcs  convert to straight lines
• estimatedAccuracy: at parcel, boundary, index set?
• GM_Surface/polygon obligatory for parcel (+index set)
• GM_Curve/polyline for boundary optional
• if boundary provides then topology attributes: TP_
• which area (surface size): compute, or use LKI, AKR?
• label is obligatory (last part of parcel number?)
• referencePoint must be within parcel (label place?)
October 3, 2015
28
Future attention points
•
•
•
•
•
•
3D Parcels needed?
all relevant attributes present?
parcels by topology only (no polygon)?
include products in WFS and WMS (portrayal) services
efficient conversion from LKI (coordinates, XML format)
relationship/integration with rights/owners
(INSPIRE ‘external associations’)

Land Administration Domain Model
ISO 19152 (LADM)
• Model includes:
• Spatial part (geometry, topology)
• Extensible frame for legal/admin part
• Object-orientation  express in UML
• Model Driven Architecture (MDA)
• FIG proposed LADM to ISO TC211, January 2008
• Accepted after voting by P-members
• ISO 19152 – started in Copenhagen/May 2008,
followed by Delft/Sept 2008 and Tsukuba/Dec 2008,
Next meeting Oslo/May 2009

Conclusion ISO-INSPIRE
•
•
•
•
•
Standardization is a condition for realizing the GII
Domain models (themes) contain knowledge
INSPIRE is mega-construction
ISO (TC211) is often the foundation
ISO 19152 / LADM and INSPIRE cadastral parcel have
different scope, but the overlap does fit
