    Digital Elevation Model is a description of the relief in the form of a model, where the height of the relief is given for each node of the square grid. The model represents a Digital Relief Model of Slovenia and Digital Elevation Model with grid size 5 x 5 m (DMV 5). Digital Relief Model of Slovenia was established using various geodetic data, using the method of weighted aggregation from resources with some geomorphological corrections. It was made in 2001-2005 and is available as a model in a square grid with a cell size 12.5 m, 25 m and 100 m (DMV 12.5, DMV 25 and DMV 100). DMV 5 was created in 2006 and was regularly maintained until 2014 using cyclic aerial survey of Slovenia (CAS). Some additional data sources were used to produce the model as well. The data of both models are available as ASCII files (y, x, H), for example: 401000.0 112000.0 251.71 401025.0 112000.0 241.03 401050.0 112000.0 230.51 401075.0 112000.0 219.88 401100.0 112000.0 208.31 401125.0 112000.0 195.45

    The database contains data about SLOvenian Absolute Model of Geoid from the year 2000 (SLOAMG2000). It is an astro-gravimetrical model, determined by a combined method. It is calculated by the least squares collocation method, using the "remove-restore" techniques. It refers to the GRS80 ellipsoid. The global geopotencial model EGM96 is used for the calculation. It is given in the form of a grid. The geoid model is used for the transformation of the ellipsoid heights (GNSS technology) into the normal-orthometric heights (above sea level) and vice versa. Heights above the sea level refers to the Slovenian height system SVS2000 with Trieste datum. The ondulation of geoid in Slovenia range from 44,140 to 48,724 m, with an average value of 46,453 m. Note: values are given only within the boundaries of Slovenia.

  • Lasersko skeniranje je eden od načinov zajema podatkov v prostoru, katerega rezultat je oblak tri-dimenzionalnih točk. Uporablja se tudi izraz LiDAR (ang.: Light Detecting And Ranging). Laserski skener oddaja svetlobne pulze in zaznava njihove odboje od predmetov v prostoru. Položaj objektov v prostoru se določa na podlagi znanega položaja laserskega skenerja, ki registrira prostorske smeri in meri dolžine poti odbitih žarkov. Rezultat laserskega skeniranja je oblak točk, ki imajo določen položaj v prostoru. Z obdelavo tega oblaka dobimo uporabnejše podatke: georeferenciran in klasificiran oblak točk (GKOT), različni digitalni modeli višin in podobno. Hkrati z laserskim skeniranjem je možno zajemati tudi aerofotografije s čimer lahko vsaki točki v oblaku priredimo tudi barvo in izdelamo (popolni) ortofoto. V okviru Cikličnega laserskega skeniranja Slovenije 2023-25 so na voljo različni izdelki: - GKOT - georeferenciran in klasificiran oblak točk - DMR - digitalni model reliefa - DMP - digitalni model površin - nDMP - normaliziran digitalni model površin - POF - popolni ortofoto - POFI - infrardeči popolni ortofoto
