NGU Superficial Deposits of Norway - best of
The Superficial Deposits of Norway (best of) is a database giving full coverage of the superficial deposits throughout Norway. High resolution data at scales of 1:20 000 to 1:50 000 exists for only about 30% of the country, mostly in areas where superficial deposits are of significant economic importance. The deposits are classified according to their genesis and thickness. For most of the data collated at a scale greater than 1:250 000 derived information such as groundwater potential and infiltration capacity have been added as attributes.

Løsmassene er en fundamental naturressurs på linje med vann og luft. De utgjør selve grunnlaget for plante- og dyreliv, og dermed for landbruk og bosetting. Løsmassedata er et nødvendig hjelpemiddel for å oppnå fornuftig arealdisponering og en best mulig forvaltning av løsmassene. Datasettet kan anvendes som underlag i overordnet areal- og miljøplanlegging, sårbarhetsanalyser, vurdering av grunnforhold, grunnvannspotensiale og infiltrasjonsmuligheter.

Data Quality

1G-E:geometricHarmonization=yes
1G-E:thematicHarmonization=yes
The data set is based on printed Quaternary maps. The data set "best of" cover the whole country, but in different scales. The field mapping work is most often carried out on base maps in scale 1.50.000 and generalized and aggregated afterwards for presentation in smaller scale printouts (for each county). Several of the manuscripts represent transparent foils from these printed maps. The maps where scanned and vectorised in Microstation and then exported to ArcGIS format, where several attributes (derived themes) are added to the data set according to the Norwegian feature catalogue SOSI. The data set contains at the moment only superficial deposit polygons and boundary lines, but will later on also contain structure lines and point symbols. Derived themes like infiltration capacity and ground water potential are also included, suitable as best practice information and guidance for the customer.

Løsmassedata i målestokkområdet 1:250.000 er beregnet for å gi en regional oversikt. I kommunal planlegging er det behov for mer detaljerte løsmassedata (N50 og større).
