A spatio-temporal building exposure database and information life-cycle management solution

Summary

This is a prototype implementation of an information life-cycle management solution, based on a relational spatio-temporal database model. Two fictious application scenarios focusing on the modelling of residential building stocks and their changes during different phases of the disaster risk management cycle are provided to show the capabilities of the solution in the context of disaster risk management.

Dependencies

PostgreSQL 9.2 or higher PostGIS 2.0 or higher

Installation

Create empty database

$ createdb sensum_db -h localhost -U postgres

Add main database model

$ psql -h localhost -U postgres -d sensum_db -f main_db.sql;

Add multi-temporal support to the database model

$ psql -h localhost -U postgres -d sensum_db -f add_temporal_support.sql;

Add multi-resolution support to the database model

$ psql -h localhost -U postgres -d sensum_db -f add_resolution_support.sql;

Add sample taxonomies to the database model

$ psql -h localhost -U postgres -d sensum_db -f add_taxonomies.sql;

Scenarios

Load scenario data

$ psql -h localhost -U postgres -d sensum_db -f scenario_2_data.sql;

Run scenario

$ psql -h localhost -U postgres -d sensum_db -f scenario_2.sql;

Explore scenario with example queries or by looking at the run scenario scripts

scenario_2_queries.sql

Make sure to clean scenario data and history before running a new scenario
