AAA Data Model

AAA data model, applied for official geospatial reference data across Germany, guarantees inter-operability between all 16 state (Länder) surveying authorities

Implementation Partnership

Harmonised identification of datasets for INSPIRE

8 states of Germany are making use of the same software solution (XtraServer) for delivery of AAA data via web services (implementation partnership).

INSPIRE Datasets

Surveying authorities are public authorities according to INSPIRE

Development of a uniform solution for making INSPIRE viewing and download services available is well underway!

Implementation in Lower Saxony

Decision to implement INSPIRE for

the 16 Federal states (Länder):

Various approaches –

centralised or decentralised

General Requirements:

• IT-Service Providers to enable

24/7 service availability

• Individual emergency manuals

for the IT-Providers

• Budget and human resources

(including individual training

times)

• Skilled (new) staff

Surveying and Mapping Authority

of Lower Saxony:

• VKV is well positioned

• Technical infrastructure and

know-how are in place

• AAA data model as excellent

starting point

• INSPIRE conformant data from

permanently updated reference

datasets

• Coordination tasks are time

consuming

• INSPIRE deadlines are a

challenge, but will be met!

Other administrative bodies of Lower Saxony:

With the need to provide conformant data and its services, call for

collaboration has constantly been increasing.

Experience: Shift from decentralised to centralised

approach is useful!

Intention to provide other stakeholders with the surveying

administration solution

Centralised Data Delivery Platform


• Experience transfer from surveying authorities

• Centralised approach, using the same IT-infrastructure

• Provision of know-how only once

Open to participation of other bodies of Lower Saxon state

administration

Participation of local authorities is being

considered, but legal questions to be solved

and organisational obstacles to be overcome

Conclusions


INSPIRE data to be provided on request- with conversion to INSPIRE ‚on-the-fly‘

Shift to centralised service delivery, experiences from other states valuable

State Survey to provide strong technical support to other INSPIRE stakeholders

Information on INSPIRE is spreading slowly - constant promotion is necessary

Coordination Office GDI-NI to be expanded
