Digital Elevation Model (DEM) eli digitaalinen korkeusmalli on maanpinnan korkeuseroja kuvaava kolmiulotteinen tietomalli. Malli esitet\u00e4\u00e4n usein ruudukkomuotoisena rasterina, jossa jokaisella solulla on yksi korkeusarvo.<\/p>\n\n\n\n

DEM-malleja k\u00e4ytet\u00e4\u00e4n laajasti paikkatietoanalyysiss\u00e4, kaupunkisuunnittelussa, ymp\u00e4rist\u00f6arvioinneissa, tulvariskien kartoituksessa, infrastruktuurisuunnittelussa sek\u00e4 visuaalisissa simulaatioissa. Niiden avulla voidaan tehd\u00e4 esimerkiksi rinne- ja valuma-alueanalyysej\u00e4, n\u00e4kyvyyslaskelmia sek\u00e4 maisemamalleja.<\/p>\n\n\n\n

Korkeusmallit tuotetaan tyypillisesti kaukokartoitusmenetelmill\u00e4, kuten laserkeilauksella (LiDAR), fotogrammetrialla tai tutkamittauksella. DEM-tietoa voidaan yhdist\u00e4\u00e4 paikkatietoj\u00e4rjestelmiin (GIS), jolloin se tukee p\u00e4\u00e4t\u00f6ksentekoa ja tarkempaa maastotiedon hallintaa.<\/p>\n\n\n\n
