The Topo (Finland) map in Lokimaps uses the National Land Survey of Finland's official topographic cartography. The main authoritative reference is MML's 2025 topographic map legend, which explains symbols at scales from 1:10,000 to 1:250,000 in Finnish, Swedish, and English.
This page explains how the main symbol families fit together. Keep the official legend open when you need to identify the exact line, fill, or point symbol on the map.
Detail changes as you zoomDetail changes as you zoom
The map is not one drawing enlarged and reduced. MML's raster topographic map series uses products prepared for different scales. Smaller roads, individual buildings, auxiliary contours, vegetation details, and minor place names appear only at closer zoom levels. At wider views, features are simplified or omitted to keep the map readable.
If an important feature is missing, zoom in before concluding that it is absent. If the same feature looks different after zooming, interpret the symbol used at the current scale.
At the closest app zoom levels, Lokimaps enlarges the most detailed available raster tile. Lines and text become larger, but no new survey detail appears. A sharp-looking enlarged symbol is still limited by the source scale.
Contours and landformsContours and landforms
Brown contour lines join points of equal elevation. Closely spaced lines indicate a steep slope, while wide spacing indicates gentler terrain. Index contours are emphasized to help count elevation, ordinary contours fill the intervals between them, and auxiliary contours may show smaller landforms at the most detailed scales. The vertical interval changes by scale, so use labelled heights and the official legend instead of assuming one fixed interval.
Additional terrain symbols identify cliffs, steep slopes, exposed bedrock, boulders, rocky ground, sand, gravel or extraction areas, and measured height points. A closed contour can describe a hill or a depression, depending on its markings and the surrounding elevations. Shading or a rock symbol does not by itself tell you whether a place is passable.
Forest, open ground, fields, and wetlandsForest, open ground, fields, and wetlands
Background colours and patterns distinguish broad land-cover types, including forest, fields, gardens, meadows, open ground, brush, and developed areas. At closer scales, the legend also differentiates coniferous, deciduous, mixed, and scrub vegetation.
Wetlands have their own blue patterns. The symbols distinguish combinations such as open or forested marsh and easier or more difficult terrain, as well as paludified ground. Treat these as mapped land-cover classifications, not a live statement about water depth, ice strength, seasonal flooding, or safe passage.
Roads, tracks, paths, and crossingsRoads, tracks, paths, and crossings
Road symbols distinguish motorways and different road classes from smaller roads, access drives, tractor tracks, and paths. Width or prominence on the map expresses the mapped class, not a guarantee that a vehicle may use it. Barriers, gates, tunnels, bridges, ferries, winter roads, bicycle paths, duckboards, and railway features use separate symbols.
For route planning, check the exact official symbol when a line could be a road, track, path, power line, administrative boundary, or watercourse. Access rights, closures, maintenance, snow, and surface condition are not encoded comprehensively in the topographic map.
Water and shoreline featuresWater and shoreline features
Blue features include lakes and sea areas, rivers, streams, ditches, springs, wells, rapids, dams, and flow direction. Shoreline styles can distinguish a surveyed edge from a diffuse or uncertain shore, a flood area, or land exposed by a receding shoreline, called reliction in the official legend. Small rocks, water holes, basins, docks, reeds, and channels have separate point or area symbols.
Some coastal context, boat routes, buoys, and depth information can appear on the topographic map. It is not a nautical chart. For travel on the water, switch to an appropriate nautical chart and use approved, current navigation material.
Buildings, structures, and landmarksBuildings, structures, and landmarks
Building colours and shapes distinguish residential buildings, holiday homes, commercial and public buildings, and other structures. The legend also covers churches and cemeteries, towers, chimneys, masts, wind turbines, observation towers, monuments, ski lifts, fences, gates, campfire sites, and historic industrial features such as tar pits.
A symbol normally indicates the mapped feature type, not whether a facility is open, maintained, publicly accessible, or still present. Check current local information for shelters, crossings, services, and restricted sites.
Boundaries and protected areasBoundaries and protected areas
Different line styles identify national, regional, municipal, protected-area, and special-area boundaries. A boundary line can overlap a road, shore, or other linear feature, so inspect the pattern and nearby labels carefully.
The official MML legend also includes cadastral symbols. In Lokimaps, detailed property boundaries belong to the separate Property borders (Finland) layer and appear only when that layer is enabled. They are not part of the Topo base map alone.
A practical reading orderA practical reading order
When planning a route, read the map in layers:
- Use contours, cliffs, rock, and wetlands to understand the terrain.
- Identify the exact road, track, path, bridge, or ferry symbols.
- Check watercourses, shorelines, and likely crossing points.
- Look for buildings and landmarks that can confirm your position.
- Inspect protected or special-area boundaries and verify current access rules separately.
- Zoom in and compare the unfamiliar symbol with the full official MML legend.
MML's official legend warns that information in the underlying topographic database is updated at intervals of 5 to 10 years and that one map sheet can combine information from different years. Map data and cartography are updated over time. MML publishes service notices about topographic-map changes, so the current official legend takes precedence over older printed keys or screenshots.
