The free web map application called Maankamara includes features such as precise elevation data hillshading, superficial deposits and bedrock maps and aerial photographs. Maankamara replaces GTK's old Geokartta application.
GTK has implemented a multidirectional hillshading technique for the new application. The elevation data increases the value of the superficial deposits maps and makes them easier to interpret. The National Land Survey of Finland provided the base maps and aerial photographs for the Maankamara application. The basic elevation models and laser scanning basic data was also produced by the Land Survey of Finland, but was processed and visualized by GTK.
The superficial deposits maps are available at scales of 1:1 000 000, 1:200 000, 1:50 000 and 1:20 000. The bedrock maps are available at scales of 1:1 000 000 and 1:200 000. GTK's Maankamara application maps can already display elevation differences within an accuracy of 0.3 metres. The accuracy of maps available for the entire Finland is currently 1.4 metres.
The map application offers the best possible geological mapping data from each area and can be smoothly scaled. You can improve the readability and clarity of the map view by adjusting the transparency of the map themes.
