  • Data Sharing – a Case of Shared Databases and Community Use of On-Line GIS Support Systems

    Data management is becoming increasingly simple and complex at the same time. The challenge is to effectively use the increasing number of tools available to manage increasing amounts of environmental information for purposes of data capture, analysis, display, sharing and storage. Government is no longer the main collector and provider of data. Community groups possess vast amounts of data ...

  • Developing an Effective Sanitary Sewer Management Plan Utilizing Innovative GIS Solutions

    As California’s wastewater collection system infrastructure begins to age, the need to proactively manage this valuable asset becomes increasingly important. The first step in this process is to have a reliable reporting system for Sanitary Sewer Overflow (SSOs). Although there are some data systems to record spills and various spill-reporting requirements have been developed, inconsistent ...

  • Analysis of seismic vulnerability using remote sensing and GIS techniques

    This paper presents a framework to integrate several sources of spatial information to derive a map of seismic vulnerability for the city of Arica, Chile, which has been historically affected by this natural hazard. The proposed method is based on generating a geographical database with different variables that are related to human activity, considering factors of potential reduction and increase ...
