Integrated Surface Database (ISD) is global database compiled by the National Oceanic and Atmospheric Administration (NOAA) and the National Centers for Environmental Information (NCEI) comprising hourly and synoptic surface observations compiled globally from ~35,500 weather stations; it is updated, automatically, hourly.
Aerial photography, land cover data, and digital elevation models all provide coverage data. Generally, a coverage can be multi-dimensional, such as 1-D sensor timeseries, 2-D satellite images, 3-D x/y/t image time series or x/y/z geo tomograms , or 4-D x/y/z/t climate and ocean data.
The CLUI also organizes exhibitions, research projects, and public programs. The Center's programs and projects cover many types of land uses in the US, including those related to agriculture, energy, industry, mining, communication, waste management, water resources, transportation, commerce, housing, recreation, and defense and preparedness.
