SPATIAL DECISION PROCESS
Slide 4 / 27InViTo: an interactive visualization tool for supporting planning processes
INPUT 2012 - Seventh International Conference on Informatics and Urban and Regional Planning – Cagliari 10-12 May 2012
Task
Large scale planning and decision making processes supported by interactive tool.
Assumption
ICT provides nowadays a large amount and typologies of tools which offer the
possibility to visualize numerous data and relate them to specific features.
Thus, in this research, no new software has been created. Existing software have
been investigated in order to find the best fitting to multidisciplinary processes.
AVAILABLE TECHNOLOGIES AND NEEDS
Slide 5 / 27InViTo: an interactive visualization tool for supporting planning processes
INPUT 2012 - Seventh International Conference on Informatics and Urban and Regional Planning – Cagliari 10-12 May 2012
What did I look for?
A single tool to manage and display data and variables with the possibility of
obtaining customized output graphs.
Capability of relating choices and proposals to their effect on territory
transformations and possibility of visualizing outputs in real-time in order to
support workshops an focus groups.
Construction of a replicable and easy fitting method.
AVAILABLE TECHNOLOGIES AND NEEDS

Rhinoceros® (Rhino) is a stand-alone,
commercial NURBS-based 3-D modeling tool,
developed by Robert McNeel & Associates.
The software is commonly used for industrial design
and architecture.
Grasshopper™ is a graphical algorithm editor tightly
integrated with Rhino’s 3-D modeling tools. Shapes are
created using generative algorithms that can contain
different types of input including numeric, textual, audio-
visual applications.

Usually Rhinoceros and its plug-in
Grasshopper are used for industrial and
architectural design at the building or
furniture scale.

INPUT 2012 - Seventh International Conference on Informatics and Urban and Regional Planning – Cagliari 10-12 May 2012
Generative: grasshopper plug-in allows to generate shapes
without standard CAD environment modelling. Shapes are
described by a sequence of processing steps.
Parametric: mathematical functions and relationships
among them define shapes and their behaviours.
Dynamic: outputs change in real time according to user
choices following the rules of assessment method.
Easy to customize: using common scripting languages
(Python, C# or VisualBasic).
WHY RHINOCEROS AND GRASSHOPPER?

Scale factor: a software, commonly used at building scale
(or lower), are adapted to a large area planning process.
GIS: potentiality offered by script codes are used to
combine Grasshopper with ESRI GIS shapes and data.
Assessment Methods: the dynamics of various assessment
models such as multi-criteria analysis, surveys, conjoint
analysis are reproduced in order to visualize outputs.
Participatory Processes: the instrument represents a useful
tool for participatory planning.

THE STRUCTURE OF THE INSTRUMENT
A script allows the model to import geo-referenced data in
order to generate specific shapes for each indicator.

INPUT 2012 - Seventh International Conference on Informatics and Urban and Regional Planning – Cagliari 10-12 May 2012
THE STRUCTURE OF THE INSTRUMENT
Each element can be associated to a
mathematical function (e.g. based on
distance) that describe its behaviour. The
function can be manually implemented or
read from external file.

Turin Pilot Application: the instrument has been tested on the Northern
metropolitan area of Turin. The effects of new infrastructure projects
on redevelopment areas has been investigated in order to provide guidelines for
new projects on the area.
CircUse: In.Vi.To. has been set to evaluate possible land use for abandoned
brownfield in the town of Asti.
CoDe24: using ANP assessment method, main bottlenecks and critical areas
have been investigated. In.Vi.To. reproduces the assessment dynamic and
releases outputs according to ANP method.
COST TU1002: in the COST Action TU1002 about accessibility instruments,
In.Vi.To. has been tested in the town of Turin to evaluate level of accessibility to
public trasport.
COST TU0801: in the COST Action TU0801 about semantic enrichment of 3D
city models for sustainable urban development In.Vi.To is been testing in the
Skopje case study
