U svrhu bolje procjene iskoristivosti za konkretni zadatak korisnici digitalnih modela reljefa moraju biti svjesni glavnih karakteristika. U ovome se radu navode i uspoređuju karakteristike sedam ...javno dostupnih globalnih digitalnih modela reljefa na širem ozemlju Republike Hrvatske. Izabrani modeli su ASTER, SRTM, SRTM30+, ACE2, GMTED2010, GTOPO30 i ETOPO1. Za svaki od digitalnih modela reljefa navode se najvažnije karakteristike: metoda izrade, razlučivost, horizontalni i visinski datum i procijenjena točnost.
Osim toga, za šire područje Republike Hrvatske određene su i analizirane razlike između digitalnih modela reljefa u identičnim točkama, nakon što su modeli prethodno usklađeni u istu razlučivost. Određene razlike dale su informaciju o međusobnom slaganju između modela, otkrivanju područja velikih neslaganja te procjenu prisutnosti grubih i sustavnih pogrešaka. Razlike upućuju na postojanje znatnih razlika između različitih globalnih modela reljefa. Uzroci nastajanja razlika između digitalnih modela su mnogobrojni te je pri korištenju modela potrebno spoznati relevantnost utjecaja pogrešaka modela reljefa na konačne rezultate pojedine znanstvene ili stručne zadaće.
Digitalni podatki ('Digital Data') is the thirteenth volume in the series GIS v Sloveniji (GIS in Slovenia). The goal of this volume is to present the wide variety of research findings on ...geographical information systems in Slovenia in recent years. Digital data is one of the main pillars of geographical information systems, and so this volume describes opportunities to put such data to use. Recently lidar scanning technology has increased the precision and diversity of analysis. The volume clearly presents project results and research in areas such as geography, hydrology, protection against natural disasters, archaeology, transport, settlement, remote sensing, and others. Readers will discover new features regarding GIS applicability and learn about interesting findings in these areas.
Digitalni prostor ('Digital Space') is the twelfth volume in the series GIS v Sloveniji (GIS in Slovenia). The goal of this volume is to present the wide variety of research findings on geographical ...information systems in Slovenia in recent years. Thanks to the development of technology and a wide selection of digital data, GIS users can explore digital space from several aspects. The volume clearly presents project results and research in areas such as geography, hydrology, protection against natural disasters, history, literary studies, regulation of traffic and mobility, agriculture, archaeology, remote sensing, and the energy industry. Readers will find new features regarding GIS applicability and learn about interesting findings in these areas.
Modeli geomorfometrijskih parametara i drenažne mreže imaju široku primjenu u mnogim znanstvenim i civilnim granama i aktivnostima. Izrađuju se iz podataka o Zemljinoj površini koji su najčešće ...objavljeni u obliku digitalnih modela reljefa (DMR).
Glavni je cilj ovoga rada izraditi modele nagiba, smjera nagiba i drenažnih mreža za kontinentalno područje Republike Hrvatske korištenjem najdetaljnijega globalnog digitalnog modela reljefa. Izrađeni modeli su opisani, uspoređeni i analizirani te daju uvid u morfološke oblike i strukture topografske površine. Kvaliteta modela provjerena je na postojećim neovisnim podacima. Osim toga, s obzirom na to da su modeli izrađeni korištenjem različitih globalnih digitalnih modela reljefa, analizirane su razlike između izlaznih modela. Modeli drenažne mreže dodatno su analizirani ovisno o korištenim algoritmima (jednosmjerni i višesmjerni protok) i graničnim vrijednostima. Analiza osjetljivosti i utjecaja ulaznih parametara i modela na izrađene modele bit će korisna za izradu pouzdanijih budućih modela drenažnih mreža za druga lokalna i regionalna područja.
