Datasettet inneholder antatt utstrekning for kjent grunnforurensning i Lillestrøm kommune. Dataene har ulikt opphav, og det må tas høyde for ukjent/dårlig nøyaktighet på avgrensningen av flatene. Datasettet dekker ikke hele kommunen. Ved bruk i planlegging må datasettet anses som et supplement til nasjonale grunnforurensningsdata.

Datasettet inneholder lokalt registrerte kulturminner i Lillestrøm kommune, og er et viktig supplement til kulturminner fra Riksantikvaren (Askeladden). Dataene er registrert som en del av arbeidet med kommunens kulturminnevernplan i 1997 (Skedsmo). De foreligger som Esri filgeodatabase, shapefil og SOSI-fil i UTM sone 32

Kjeller Vindteknikk has on assignment from NVE made a national feasibility study of the available wind resources, both onshore and offshore. The map product has a horisontal resolution of 1x1km, and gives annual avarage at 50, 80 and 120m above the ground. The maps are available as downloadable PDF-files. In addition to available wind resources, maps of terrain complexity and risk for icing has been developed. Terrain complexity maps are an indicator on the vulnerability of turbolent air flows in an area. Turbolent air flows can be a challenge for wind turbines and will normally contribute to reduced power production and increased wearing on the wind turbines. Icing on turbine blades can be a problem in exposed areas, especially at higher altitudes, and contributes to reduction in power efficiency and power production.

The dataset includes a description of port facilities that are inspected by the Norwegian Coastal Administration pursuant to what is known as the ISPS code. This deals with port security against external threats/terrorist attacks: http://www.imo.org/ourwork/security/instruments/pages/ispscode.aspx The objects in the dataset are described with ISPS status, what type of traffic uses the port facility, and a number of circumstances such as ownership, authority, etc.
