    Geomatics-enabled Interdisciplinary Approach Based on Geospatial Data Processing for Hydrogeological Risk-analysis
    (Wydawnictwa AGH, 2024) Di Stefano, Francesco; Chiappini, Stefano; Sanità, Marsia; Pierdicca, Roberto; Malinverni, Eva Savina
    Hydrogeological risks that are associated with rivers have emerged as a significant concern worldwide, impacting both natural ecosystems and human settlements. This contribution presents an interdisciplinary project that leverages many technologies for data-acquisition and modeling to comprehensively analyze and manage risks in riverine environments. The project integrates geomatics, geological, and hydrological techniques to provide a holistic understanding of river dynamics and their associated hazards. As a central component of this project, geomatics plays a pivotal role in instrumental field surveying through the deployment of photogrammetry and LiDAR instruments. Remote-sensing data from satellite imagery further enriches the project’s temporal analysis capabilities. By analyzing this data over time, researchers can monitor changes in river patterns, land use, and climate-related variables, this helps identify trends and potential triggers for hydrological events. To manage and integrate the vast amount of geospatial information that is generated, a geodatabase within a geographic information system (GIS) has been established. It enables efficient data storage, retrieval, and analysis, fostering collaboration among multidisciplinary researcher teams. This system offers tools for risk-assessment, modeling, and scenario planning, these allow for proactive measures for mitigating hydrological risks.

    Zastosowanie narzędzi CASE do projektowania baz danych systemów informacji geograficznej
    (Wydawnictwa AGH, 2006) Dębińska, Ewa ; Cichociński, Piotr 
    The base for the effective use of the Geographic Information Systems (GIS) is a correctly constructed database allowing quick and swift browsing of the data. Because of GIS specifies, it is necessary that such a database, apart from descriptive data of the objects, also stores information referring to their location and shape. Then such a database, containing geographical information, that distinguishes it from among another databases, can be named a geodatabase. The introduction of the geodatabase model allowed the application of the methods of designing relational databases, including CASE tools, also for geographic information. Apart from theoretical considerations, the paper presents an example of the data model for the evaluation of real estate, containing the definitions of necessary object classes and their relationships.
