Loose masses, already linked to every property.
NGU's loose masses map shows the extent of the loose mass types that cover bedrock: moraine, glaciofluvial deposits, marine clay, fluvial deposits, glaciolacustrine sediments, peat, aeolian deposits and more. Most of these loose masses formed during and after the last ice age.
What the dataset contains
Loose masses in Placepoint
NGU's loose masses map shows the extent of the loose mass types that cover bedrock: moraine, glaciofluvial deposits, marine clay, fluvial deposits, glaciolacustrine sediments, peat, aeolian deposits and more. Most of these loose masses formed during and after the last ice age. Geodata AS distributes the dataset to Placepoint. The dataset only shows which soil type dominates in the top few metres of the ground surface. Thicker layers of other soil types may lie deeper and should be checked with specific ground investigations.
For a developer, the loose mass type is one of the most important single variables in plot valuation: bearing capacity, ease of excavation, drainage and potential quick clay risk below the marine border all depend on the dominant soil type. The dataset is also the basis for derived risk layers such as Possibility of marine clay and Radon susceptibility. Read it together with Bedrock, Marine border and NADAG – ground investigations (registered ground investigations). Part of Placepoint's map layers for Geology.

Datasets often read together
Bedrock, derived maps, NiN
Derived bedrock maps from NGU for Natur i Norge: forecast for lime content in the bedrock and the extent of ultramafic rocks.
About the datasetBedrock N250
The map data is mainly based on the national printed bedrock geology map series at a scale of 1:250,000, and has since been harmonised across map sheet boundaries and updated with newer map data.
About the datasetBedrock N50
The maps are built on a combined interpretation of field observations, geophysical data, digital elevation models and aerial photos, along with analyses of collected samples.
About the datasetMining rights
Areas covered by mining rights for state-owned minerals under the Minerals Act: exploration rights (UN) and extraction rights (UT).
About the datasetDrill cores
NGU's drill core archive: places where drill cores have been taken for bedrock, natural stone, metals and industrial minerals.
About the datasetGeochemistry
NGU's national geochemical database: field samples of loose masses, stream sediments and water with analysed elements, and measurement points with geochemical measurements.
About the datasetHow often are loose masses updated?
Monthly. The frequency follows the source and is shown on the dataset in Placepoint.
Where does the data come from?
From Geodata AS. We collect and quality-check the data and place it on the correct property, with source and date on every field.
How do I see loose masses on a property?
Look up the address in Fusion and turn on the Geology map layer. The dataset is there as its own layer, and the details appear in the property panel when you click on the map.
Can I get the dataset programmatically?
Yes. The same data is available in Placepoint API and in Placepoint AI through MCP, so you can bring it into your own systems and agents.
