Planning support systems for fiscally sustainable planning
No full textLocal government's need for accurate assessments and projections of the fiscal consequences of development is well established and persistent. This analysis demonstrates the use of a geographic information science-based planning support system to project residential growth and the fiscal consequences of development. The cornerstone of the analysis is a spatial index of urban form which captures clustering and dispersion of the built environment. A regression model indicates the spatial index to be a statistically significant determinant of expenditures on policing services in the study area. Modeled future growth was spatially and temporally disaggregated to indicate future residential growth at different planning horizons. Spatial indices were calculated for these planning horizons and incorporated into the econometric model for ceteris paribus evaluation of the effect of change in urban form on public service expenditures. Results demonstrate planning informed by PSS modeling has the potential to realize savings on public service expenditures
The Italian landscape of Geomatics for the faculties of Agriculture: novelties from those who get used to play second fiddle
No full textGoing along with our previous intervention Would Google Earth be a proper GIS? (Marcheggiani
2011), had during last LeGIO-workshop held in Leuven (Belgium) in November 2011 our intention is
to take advantage of the incoming 8th European GIS Education Seminar to attest the arguments we
displayed. A step further has been the involvement of GIS-teachers from the broader Italian context.
With this in mind a survey has been conducted considering the whole Geomatics background for the
Agriculture faculties in Italy. A special attention has been paid to potential kernels of new ways of GIS
and Geomatics teaching emerging by teachers and scholars. To do this a questionnaire has been
devised to test students background and to collect their opinions. The survey wants to be a gaze on the
ways in which GIS is taught in Italy today
Urban CO2 Planning: A Decision Support System
No full textPatterns of urban development affect flows of material and energy within urban settlements and exchanges with their surroundings. In recent years the quantitative estimation of the components of the so-called urban metabolism has increasingly attracted the attention of researchers from different fields. To contribute to this effort we developed a modelling framework for estimating carbon exchanges in relation to alternative land-use scenarios. The framework bundles three components: (i) a Cellular Automata model for the simulation of the urban land-use dynamics; (ii) a transportation model for estimating the variation of the transportation network load and (iii) the ACASA (Advanced Canopy-Atmosphere-Soil Algorithm) model tightly coupled with the mesoscale weather forecasting model WRF. We present and discuss the results of an example application on the City of Florence
Introduction to ‘Planning Support Systems for Sustainable Urban Development’
No full textPlanning Support Systems (PSS) are geo-information-technology-based instruments that are dedicated to supporting those involved in planning in the performance of their specific tasks (Batty 1995; Klosterman 1997). The term PSS appeared on the planning scene in the mid-1980s thanks to its progenitor, Britton Harris, although the concept of building instruments dedicated to the support of planning activities dates back much further. In this first introductory chapter a brief demarcation of the concept of PSS will be provided, besides a concise overview of the content of this book on "Planning Support Systems for Sustainable Urban Development"
The IMAGE studio: a tool for comparative internal migration analysis and modelling
No full textThis paper presents a 'studio' that will facilitate the spatial analysis and modelling of internal migration in any country. The studio is being used in a research project trying to confront the MAUP challenge for comparative analysis of internal migration in different countries by reporting on the de-velopment of a tool that generates a series of indicators relating to spatial patterns of migration for a set of Basic Spatial Units (BSUs) and aggrega-tions thereof. More specifically, the paper reports on the framework and components of the studio, its user interface and some initial experiments that explore how the frictional effect of distance on migration changes as BSUs are aggregated into larger regions in a stepwise manner, using data for the United Kingdom
Measuring location in residential location choice: An empirical study on the canton of Zurich
No full textA web-based fuzzy CA model for urban growth simulation
No full textCellular automata (CA) as an emerging technology has been adapted increasingly by geographers and planners to simulate the spatial and temporal processes of urban growth. While the literature reports many applications of cellular automata models for urban studies, in practice, the operation of the models and the calibration of the parameters in use were only known to the modellers. This is largely due to the constraint that most CA models were developed based on desktop computer programs, either by incorporating the model within a desktop GIS environment, or developing the model independent of a desktop GIS. Consequently, there is little input from the user to test or visualise the actual operation or evaluate the applicability of the model under different conditions. This chapter presents a methodology to implement a fuzzy constrained urban CA model within a web-based GIS environment using Gold Coast City in Southeast Queensland, Australia as a case study to simulate its spatio-temporal processes of urban growth. With the web-based CA model, users can visualise and test the operation of the model; they can modify or calibrate the model’s parameters and evaluate its simulation accuracies, or even feed the model with ‘what-if’ conditions to generate alternative outcomes. This web-based modelling platform provides a useful channel to foster public participation in urban planning and management
