Parametric (Geo)Design for Test Planning

Christoph Schaller
2019 GI_FORUM - Journal for Geographic Information Science  
This needs to be addressed in planning processes, as quality-oriented and sustainable internal densification is required.  ...  This paper presents a process model based on Geodesign that integrates GIS and Parametric Design, so that effects on internal densification caused by changes to building regulations can be quantified and  ...  Throughout the process, data is stored and analysed using the relational database management system PostgreSQL 9.1 with the PostGIS 2.1 extension for handling spatial data.  ...

Andrea Alonso, Andrés Monzón, Yang Wang
2017 Sustainability  
The data presented in this paper resulted from the work carried out by the authors during the project in collaboration with the rest of the consortium.  ...  Very few studies have used LUTI models to analyse anti-sprawl policies, and these few studies are more related to TOD developments [15] , than to re-densification processes.  ...  The external scenarios include a number of variables in relation to demographic and economic growth, transport data and land use development.  ...
