Project Rainbow I - Geographical Information Systems (GIS) and building stock survey

The main objective of the project is to utilize current tools for earthquake risk mitigation. In order to reach this goal a thorough microzonation of the urban area in the forefront of a damaging seismic event has to be conducted including the identification of the local building stock’s vulnerability and social preparedness.
 
In this context, the analytical investigation of buildings or derived structural systems being representative for the local building stock becomes an essential part of the study.
 
The main purpose of this project will be to apply as much of the theoretical background taught during the lessons of WS 2010/11 and SS 2011. Besides, assistance to the project progress and outcomes will be discussed in biweekly consultations (see announcement on board Marienstr. 13B, ground floor).

The project will be related to the home country of the participants, so far data are available.  Tasks to be performed in this project are:


 
1 General - Data Collection
 

  • Allocation of typical building types and their distribution
  • Importance of each construction method and their distribution over the investigation area
  • Relation to the investigation structure of this project
  • Standard procedures and specification for hazard assessment 

   
 
2 GIS - mapping of natural hazards and risk relevant data layer

  • overview about data collection
  • this is an example to give an overview over your data
