Interactive group modelling (MapTable)


MapTables can be used for interactive design processes with stakeholders, and can assist in visualising potential problems and solutions. This tool page focuses on explaining the MapTable concept and software, including spatial databases and models that can predict impacts of designs of construction works for these projects.


The purpose of MapTable is to help identify and quickly evaluate design alternatives in an interactive setting, for instance during a meeting or workshop. The concept was designed for an interactive setting, where multiple stakeholders with different backgrounds jointly brainstorm to come up with alternative solutions and out-of-the-box ideas. In such a setting, quick evaluation of alternatives can support the interactive design process and decision-making on an integrated solution. During a meeting or workshop all participants are encouraged to take part in the design process to achieve the best possible alternative. It serves as a useful communication tool for involving stakeholders.

The MapTable concept is applicable in a wide range of projects. The concept, as it was developed, aims at projects related to hydrodynamics, morphology and ecology and their interrelations. An interactive tool developed for the MapTable concept can visualise geographic changes in, for example, a coastal zone, an estuary or a river bed. Within a very short time (a few minutes at most), a first estimate of the effects on various design aspects is delivered. New insights or ideas can thus be quickly evaluated and results presented on the spot. The interactive tool is based on simple but robust models that allow for quick evaluation of different design alternatives. Making use of simple models is both an advantage (quick, interactive) and a drawback (less accurate). Results of a session are preferably verified with more detailed models and further analysis before final decisions are made.

To apply the MapTable concept one requires three basic inputs:
a) a set of routines (i.e. Matlab routines);
b) a database of local conditions and
c) a predictive model.

Together it forms a tool application. It needs to be well prepared, linked and tested before it can be used in an interactive design session. This tool page is developed for decision-makers and discussion leaders to support the use of the MapTable concept in their projects. Therefore we assume that a tool application is available and can be used directly in an interactive session. Tips and tricks for developers to modify an existing tool application or develop a new tool application are provided briefly hereafter.

Building with Nature interest

Within a Building with Nature development it is always a challenge to bring different parties and knowledge fields together, to develop new ideas in cooperation with multiple stakeholders with various backgrounds and to synthesise group ideas. The BwN approach aims to come up with eco-friendly and eco-dynamic developments and designs. Stakeholders are invited to become part of the design process, where visualisations can assist to clarify the BwN concepts, stimulate communication and gain attention from additional stakeholders as well as the broader public.

Project phases

The MapTable concept can in principle be applied in all project phases:
I. Initiation phase: to develop and evaluate alternative visions on a project area.
II. Planning & design phase: to develop and evaluate alternative solutions for a well defined problem.
III. Construction phase: to evaluate alternative construction methods.
IV. Operation & Maintenance phase: to evaluate alternative maintenance methods.

However, a specific tool can be designed for a specific project phase and might therefore not be directly applicable in a different phase.
