Geomorfologický informační systém – případy užití

Abstract

The Geomorphologic Information System (GmIS) is a special type of Geographic Information System (GIS), which can be helpful to geomorphologist in various situations in research. The fundamental functionality of GmIS is to collect, store and maintain relevant geomorphologic data in a geomorphologic database. It also has to offer special analytical tools for geomorphologic analysis. It should allow the user to generate specific geomorphologic information and create (carto)graphic, statistical and other outputs. This article presents a concept of GmIS. Further it specifies and describes situations in whose the GmIS can be helpful to a geomorphologist (use cases). These are e.g.: creation of digital terrain model and derived surfaces, creation of elementary forms, terrain mapping and processing of its results, computing of morphometric characteristic of elementary forms, creation of higher levels of morphologic forms, delimitation of watersheds, morphometric characteristic of watersheds, support of geomorphic network creation, etc.
