tools usage by surveyors and by all decision-making
participants to serve the goals of good governance; Share good practice
on managerial processes and infrastructure required for data handling,
using of information and knowledge distribution; Share good practice and
develop high-level methods and techniques for merging and managing
updated spatial information at various levels according to market
requirements; Establish and maintain data – and data-quality-standards –
relevant to SIM, while cooperating with international spatial data
standards committees; and, Encourage the use of spatial information
within e-government and ecommerce. Based on these terms of reference and
missions, Commission 3 Working Groups have focussed on the contribution
of spatial information for sustainable development. Commission 3 also
addressed the phenomenon of rapid urbanization and its impacts with
emphasizing on the identification of spatial tools and general
principles, norms and standards designed for good governance whilst
using reliable and accessible spatial information.

Working Group 3.1 - SIM Infrastructure
POLICY ISSUES
SIM has the role of an integrator of components for a Spatial Information
Infrastructure especially for urban areas within the information society. SIM
is a facilitator for IT based services for planners, administration as well as
for citizens. The topics of this activity are:
- NSDI / GSDI: Spatial Data + Information Infrastructure
- Modelling, geo-visualization
- Legal aspects in SIM
- SIM and LBS as tools:
- Making geo-database suitable for mobile phones
- Improve basic references (geo-referencing, transport-internet)
- Role of surveyors in LBS
- Share current experiences and technical visions of the future.
- Gain knowledge from industry.
- Inform future decisions and implementations.
- Inform the big picture on drivers, trends and technologies.

Working Group 3.2 - Technical Aspects of SIM
POLICY ISSUES
New tools, techniques and policies are required to baseline and integrate the
social, economic and environmental factors associated with spatially managing
urban areas in general and cities/megacities in particular. Inter alia, to
monitor growth and change across the urban environment and to forecast areas of
risk – all within shorter timeframes than previously accepted. Moreover, they
must be flexible enough to meet traditional needs such as land development,
tenure and value applications, but be designed to be interoperable and integrate
within the city wide SDI as it evolves. There is a need to have access to
spatial data from wide range of sources, to integrated spatial information from
the SDI and thus leading to a more joined-up, proactive decision making allowing
the prioritising of scarce resources to tackle the most sensitive and risk prone
areas. Within the list of sub-titles includes:
- Technical Aspects
- Data collection, recording and updating, low-cost methods and tools
for environmental monitoring,
- Renewable and innovative technologies for data collection
(photogrammetry, LiDAR, crowd sourcing, PDAs, cell-phones, etc.),
- Visualization of information,
- Standardization of information and metadata,
- 2D, 3D, 4D spatial data recording and management to support the
legal integration of informalities, the decision making, the
risk-assessment and disaster management in areas with informal
settlements,
- Integration and update of spatial data-bases regarding ownership
rights, value of real estate property, and state applied regulations and
restrictions on the use rights, tools, and Land Information Systems
These technical aspects will be dealt in relation to legal, social, economic,
educational, and policy implications

Working Group 3.3 - D Cadastre (Joint Working Group with
Commission 7)
The increasing complexity of infrastructures and densely built-up areas
requires a proper registration of the legal status (private and public), which
only can be provided to a limited extent by the existing 2D-cadastral
registrations. Despite all research and progress in practise, no country in the
world has a true 3D-Cadastre, the functionality is always limited in some
manner; e.g. only registering of volumetric parcels in the public registers, but
not included in a 3D cadastral map, or limited to a specific type of object with
ad hoc semi-3D solutions; e.g. for buildings or infrastructure. The main
objective of the working group is to establish an operational framework for
3D-Cadastres. The operational aspect addresses the following issues:
- A common understanding of the terms and issues involved. Concepts should
be refined and agreed based on the ISO 19152 Land Administration Domain
Model.
- A description of issues that have to be considered (and to what level)
before whatever form of 3D-cadastres can be implemented. These will provide
'best practices' for the legal, institutional and technical aspects.
Topics to be dealt within the activity of the working group are:
- 3D-Cadastre: models, SDI and time
- 3D-Cadastre and the usability
Options for realization of a 3D cadastre model will include:
- Minimalistic 3D cadastre (no cables, pipelines etc.)
- Topographic 3D cadastre
- Polyhedral vs. Non-polyhedral Legal 3D cadastre
- Topological Legal 3D cadastre
