NGU Depositi superficiali della Norvegia
Il database dei depositi superficiali della Norvegia rappresenta l'intera copertura dei depositi superficiali della Norvegia. I dati ad alta risoluzione (scale da 1:25k fino a 1:50k) esistono solo per il 30% del territorio; prevalentemente sono coperte le aree in cui i depositi superficiali hanno un rilevante significato economico. I depositi sono classificati in base alla loro genesi e al loto spessore. Per molti dei dati (dati a larga scala come 1:250.000) sono stati derivati attributi relativi ad informazioni quali, il poteziale dell'acquifero e la capacità di infiltrazione.

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:percentCoverage=100;
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.

Constraints
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).
I depositi superficiali alla scala 1:250.000 forniscono solo una panoramica regionale. Per pianificazioni territoriali a scala comunale occorrono dati di maggior dettagli (scale 1:50.000 e/o maggiori).
