BACKLINEtourFinDR – 3D ski touring maps by BACKLINE

3D ski touring map Italy

The BACKLINEtourFinDR helps you prepare ski tours at home – free in the browser, without an account and without an app. It does not clear any tour and replaces neither the avalanche bulletin nor the assessment on site.

Features at a glance
  • Slope angle and north-facing slopesYellow 30–34°, orange 35–39°, red 40° and more. North-facing slopes (N, NE, NW) from 30° can be highlighted in blue. Calculated – no danger assessment.
  • Measure distance with elevation profileDraw a free line into the terrain: length, ascent and descent as approximate values and the calculated terrain slope along the line – deliberately without walking time and without GPX.
  • Protection zonesNo open protection zone data for Italy – the map shows no zones; that does not mean there are none. Follow the signs on site.
  • Summits, huts, routes and car parks6,635 summits, 2,621 huts, 1,183 bivouacs, optional ski touring routes (for orientation only) and around 77,000 car parks from OpenStreetMap (incomplete, unchecked).

Accuracy of the terrain model: Calculated from a terrain model of about 30 m – steep steps and gullies are often missing or look flatter; the slope can be steeper than shown. No clearance.

“Share” and “Copy link” keep the chosen map view, the layers switched on, the north-slope highlight and a line you drew yourself.

Protection zones: no data1

1 No open protection zone data for Italy – the map shows no zones; that does not mean there are none. Follow the signs on site.

How to use: drag to move, mouse wheel or two fingers to zoom, right mouse button or two fingers up/down to tilt. Tap a zone or car park for details. “Measure distance” draws a line with an elevation profile.

What the map shows

Forest, roads, tracks and paths

Forest (green), roads, farm and forest tracks and paths from OpenStreetMap (via OpenFreeMap). Paths and tracks appear from a medium zoom level. The lines show the mapped course, not whether a path is tracked, cleared or passable in winter.

Lifts and car parks

Cable cars, gondolas, chairlifts and drag lifts from a medium zoom level, with names when zoomed in – only their position, not whether a lift is running. 77,465 car parks within the Alpine part of the map (blue “P”). Car parks: publicly accessible entries from OpenStreetMap (private, customer and residents' car parks and garages left out) – incomplete and not official. Check access, fees, parking rules and winter clearing on site.

Huts and bivouacs

2,621 huts and 1,183 bivouacs or self-catering huts within the map, with names when zoomed in. Huts and bivouacs: entries from OpenStreetMap – incomplete, not official. Check with the operator or the Alpine club in advance whether a hut is open or has an open winter room.

Summit names and wildlife feeding sites

6,635 named summits from 1,000 m with the elevation recorded in OpenStreetMap; when zooming out, the main summits remain. 37 wildlife feeding sites recorded in OpenStreetMap – these entries are very incomplete; missing points do not mean there is no feeding site.

Slope angle and north-facing slopes

Yellow marks slopes of 30 to 34°, orange 35 to 39° and red 40° and more. Slope angle calculated from a public terrain model. For this region the data provider only has coarser elevation models (EU-DEM or SRTM, about 30 m) – much coarser than the 10 m model in Austria. Steep steps, gullies and cornices are often missing or look flatter; the actual slope can be considerably steeper. No clearance and no assessment of avalanche danger. Blue: north-facing slopes (N, NE, NW) of 30° and more, calculated from the terrain model.

Measure distance and elevation profile

With “Measure distance” you tap points along your planned line on the map. Below it the elevation profile appears with length, ascent and descent in metres, highest point and the steepest calculated terrain slope. Elevations come straight from the terrain model, without the map's 3D exaggeration. The profile is coloured by the slope of the terrain at each point (30–34°, 35–39°, 40° and more), not by the gradient of the line – a flat traverse through a steep slope therefore shows as steep. Slopes above and beside the line are not assessed. There is deliberately no walking time, because it depends on the conditions, no download and no saving. The values are guidance for preparation, not a clearance.

Wildlife rest and protection areas

For the Alps of Italy we have not found open data on wildlife rest or protection areas that we may show on a website with advertising. The map therefore shows no zones – that does not mean there are none. Protected areas and closures are signposted on site; national parks, nature parks and municipalities provide information. Protection zones in our 3D maps: Austria only Tyrol and Vorarlberg, Germany the DAV forest and wildlife protection areas in Bavaria (without the statutory wildlife protection areas of the district offices), Switzerland the wildlife rest zones of the cantons with freely usable data. For Italy, France and the other Austrian states we have not found open data we may show.

Ski touring routes (optional)

Two separate layers, both switched off when the map opens and only visible when zoomed in: 10,696 ski touring routes from swisstopo, created with the Swiss Alpine Club SAC, in Switzerland and the neighbouring border areas (turquoise) – according to swisstopo checked for wildlife compatibility by the cantonal hunting authorities and updated every year; according to the dataset, some border routes come from DAV, ÖAV and AVS, the Petzl Foundation / Skitourenguru or topo.verlag. Plus 1,797 ski touring routes from OpenStreetMap in the Alpine area (pink) – entries by volunteers, unchecked and incomplete. Tap a route for name, destination, source and disclaimer; “Analyse in elevation profile & slope check” hands the line to the elevation profile with calculated terrain slope. No walking times and no GPX download.

All route lines serve solely as a digital frame of orientation while preparing at home. They are neither an official route clearance nor a recommendation by BACKLINE. In high mountains in winter there are no fixed paths – avalanche conditions, snowpack and visibility on site decide where the track actually goes. Missing lines do not mean a tour is impossible or not allowed there; existing lines do not mean a route is passable or allowed.

Avalanche conditions

The map shows no danger levels. You find the current official bulletins on our avalanche bulletin map (page in German, bulletins available in English). Read the complete original bulletin of the warning service before every tour.

In high mountains in winter there are no fixed paths – avalanche conditions, snowpack and visibility on site decide where the track actually goes.

For Italy there is no nationwide topographic map and no current aerial image that we may show free of charge on a website with advertising. The winter relief therefore shows the terrain with towns, lakes, forest and paths from OpenStreetMap; the satellite image dates from 2016 and is coarser than an aerial photo.
