What problem Bytom is tackling within LUMASEC? How to re-use large area 2 km 2 devastated by coal-mines industry that is situated in very important part of Bytom? It's located around nodes of highway A 1 and regional beltway High differentiation of property ownership municipality owns little part of properties large cost of land preparation for business needs contaminated soil caused by the industry hudge amount of deposits Very few investors interested only in narrow zones along main roads

LUMASEC POLYGON

Local Support Group and Lumasec Output Local Suport Group: property ownership, investors, local government, local community participants, managing authority, researchers in urban and regional economics and land use planning. Sets of foundations that will help to work out future spatial development plan Tools and indicators for monitoring of land use development process Model of cooperation between local stakeholders Recommendations for local, regional levels

Planning Problems local perception of the problem UNPLANNED REACTIONS INADVERENT CAUSE Unforeseen side effects of our past decisions BYTOM LUMASEC POLYGON ACCIDENTAL CAUSE Unforeseen cause nature, weather, earthquake TRIAL and ERROR SOLUTION Nobody knows right solution Every solutions seems temporal EMERGENT SOLUTION The solution is changing the problem Problem is returning in different form INTENTIONAL CAUSE Conflcting interests and plans that work, conspiracies MECHANICAL CAUSE Perfect procedures Our own errors COMPROMISE SOLUTIONS There are some solutions, not just good or bad but only better or worse for different people OPTIMAL SOLUTION There is one best solution that we've got to find and work on PLANNED ACTIONS

BYTOM Spatial Data Infrastucture - GIS Bytom has got well established Data Management System keeping records of lands and buildings and geodetic managing inputs to the mains (geometric changes, ownership structure, land use management). It's leading municipality on field of LIS/GIS. Spatial data are published via portal City's Internet Plan That system was used so far by planner as a place where they store and analyze planning, landuse management related data (register of plans, building permits) … but it missed to used for planning more directly LSG proposed to create Planning Support System that can help to work on spatial development plans and become a tool of monitoring of land use development process

GIS Based Planning Support System for Bytom

Community. Viz participatory decision support tool for planners

Community. Viz – Bytom Lumasec Area alternatitve landuse scenarios side by side

Community Viz participatory decision support tool for planners An GIS-based tool designed to facilitate discussion among stakeholders about local or regional development An application have an appeal of computer game It can be used effectively by both expert and non-expert audiences, decision makers and stakeholders themselves and not only by computer (GIS) specialists - modellers An interactive and iterative approach to modelling allows users to create and explore different possible scenarios of the future for their city, region, so it actively involves users in both the creation and evaluation of scenarios It can use effectively Spatial Data infrastructure, it's open to external data as well as external analytical models

Community Viz participatory decision support tool for planners An integrated GIS model becomes a common evaluation languge of the social, economic, and environmental consequences of scenario choices on custom-built approach clearly illustrates “on the fly” the relationships between choices and consequences deals effectively with both quantitative and qualitative, spatial, non-spatial data deals openly with the uncertainties, making assumption visible rather than obscuring them can be readily customized without proffesional programming skills to reflect and highlight the values and beliefs of the user.

Community Viz participatory decision support tool for planners The purpose of PSS is to encourage thinking about landuse development and it's consequences to create a meaningful and relevant experience for users to represent decision-making as the complex and necessarily value-laden task holistic understanding of problems and their complexity What if? possible futures rather than predicting the future on a base of current trends (we not find solution or optimize but inform about responses to user decisions) Successful scenario, is developed by the user in iterative process of reviewing results, changing input assumptions, data and re-evaluating results.
