Karttaselain is a mapping app that brings Finland’s topographic maps, aerial photos, urban plans and basic marine and property data into a single, offline-capable package. It is designed for hikers, boaters, landowners and field professionals who need reliable location data on the go, combining national survey maps with GPS tracking, GPX import/export and a map feedback tool. The free tier provides detailed topography, ski and hiking trail points, aerial imagery and basic depth and property outlines, while optional Plus features extend marine, property and planning data.
Karttaselain delivers official topographic maps from the National Land Survey alongside aerial imagery that covers all of Finland and detailed urban maps with street names and numbers. The app also includes basic depth charts for small lakes and a property map with periodically updated boundaries and codes. Navigation tools include accurate GPS location, track recording, speed display, map rotation to direction of travel, a compass and a directional line showing distance to a selected target. Users can save places and routes, import and export GPX files, open locations from other apps and send map feedback to help improve the data.
The Plus subscription expands the dataset and workflow: enhanced depth charts and Transport Infrastructure Agency marine maps provide more comprehensive contours for boating and fishing, and the continuously updated property map enables property searches and area data. Additional Plus features include hillshade and forest orthophotos, secure waypoint and route storage linked to your Karttaselain account, automatic synchronization between web and mobile, route planning and area calculation for drawn regions, convenient offline map downloads and support for tracking devices such as dog GPS or personal trackers. A 14-day free trial is available and subscription options include two months for EUR 9.99 or 12 months for EUR 39.99, usable on up to four devices; multi-user business licenses and customer service are offered for account and technical support.
The interface focuses on clear map reading and straightforward navigation controls. Map rotation, compass readouts and an optional directional guide make it easy to orient in the field, while GPX import/export and keyword-based place management streamline trip preparation and record keeping. Plus subscribers benefit from slope shading and forest orthophotos that improve terrain understanding for route choice and planning. The app is developed with community input and regular updates add data layers and refinements based on user feedback.
Karttaselain is a practical, data-rich mapping tool for users who need authoritative maps and flexible offline functionality. Whether you rely on the free maps for everyday navigation or require the advanced marine, property and planning tools in the Plus tier, the app aims to consolidate multiple map sources into one accessible mobile experience.
