04 / SOURCES & DOWNLOADS

Built on public knowledge.

The provenance, files and decisions behind the national atlas.

01

GURS · Digital elevation model 5 m

The primary terrain source. All four DMV0050 quadrant archives, acquired through the public JGP service. Original model produced in 2011–2014; the portal package is labelled 2007–2016.

02

Javni geodetski podatki

Public download portal. Path: Državni topografski sistem → Digitalni model višin → DMV 0050. Archives DMV0050_SZ, SV, JZ and JV.ZIP.

03

GURS · Register zemljepisnih imen

Official geographical names. Snapshot package dated 7 November 2026, listed under CC BY 4.0 on OPSI. Used only as provisional nearby summit labels; no height values are taken from its text-size field.

04

OPSI · Data reuse and attribution

The public elevation dataset is listed under Creative Commons Attribution 4.0. GURS source attribution is retained on the map and in the documentation.

05

Water-sweep prominence algorithm

Dumitrescu & Diac: An Efficient Algorithm for Computing Mountain Prominence in Almost Linear Time. The paper describes terrain connectivity, union-find and boundary classification.

06

Earlier Slovenian prominence work

Miha Čekada, Določanje izrazitosti vrhov, Planinski vestnik, March 2016, pp. 47–50. An earlier LiDAR-based study of Slovenian two-thousanders. Background reference; not imported as our result.

07

OpenStreetMap & Leaflet

OpenStreetMap supplies the street basemap; Leaflet supplies the interactive map. Our relief, contours and summit coordinates are derived from GURS data. OSM attribution and tile usage rules apply.

08

CLSS · Newer LiDAR for the next validation

Slovenia’s 2023–2025 survey offers a newer 0.5 m terrain model. This is a future comparison source, not an input to the current catalogue.

09

GURS · Statistical regions and national outline

Twelve official statistical-region polygons from RPE, snapshot 1 November 2026, CC BY 4.0. Full geometry determines memberships; their union defines the Slovenian output outline.

10

GMBA · Mountain Inventory v2.0

Standard basic (leaf) mountain areas, CC BY 4.0. These are generalized research boundaries; exact source names remain in metadata. Slovenian names include editorial translations, and Pohorje is included in the northeastern prealps unit.

11

GMBA · Licence and research method

Open-data licence for the Global Mountain Biodiversity Assessment inventory. No mountain area is inferred for unmatched points; they remain under Other hills.

Same inputs. Inspectable output.

Project concept and development. Terrain, geographical names, region boundaries and basemap retain their own source credits and licences.

From a conversation to a landscape.

This atlas began with a question shared by two hikers and programmers: could public elevation data reveal the hills and mountains around us, including the unnamed ones?

We chose Gorenjska as a first study area, used a generous rectangular window, and preserved room around it for connecting terrain. We then extended the exact same 5 m approach nationwide and added statistical regions, mountain areas and an optional 100 m external border strip. The catalogue remains a research result tied to its data and definition.

  • 08 Nov 2026 · Source inspectionChecked the 100 m archive and selected the finer 5 m model.
  • 08 Nov 2026 · Algorithm and testsImplemented native-grid sweeps, conservative boundary bounds, plateau handling and an independent oracle.
  • November 2026 · National runLoaded 823.8 million samples; generated the catalogue and resolution comparison.
  • Next · Validation and expansionReview names, compare newer LiDAR and add broader cross-border terrain to resolve more saddles.
