How well have the observations been checked?
Land Cover for WyomingBased on informal field checking, the accuracy of the land cover data is 79.6%. The accuracy is not based on a formal quantative assessment. Field checking was performed by personnel from agencies such as the BLM, Forest Service, Fish and Wildlife Service, Natural Resource Conservation Service, Wyoming Game and Fish Department, and the Nature Conservancy, on a volunteer basis.

LiDAR Digital Ground Model (DGM) ElevationAll data products produced from the 'bare-earth' elevation data and described by this metadata are digital tabular, digital TIN or digital raster data. They contain no additional attributes beyond the elevation value assigned to each spatial coordinate location. The ASCII file version of the data contains no header, but is stored as unique identifier, easting, northing, elevation.Related Questions

However, to provide a complete global coverage, estimation of SSTs at all pixels that are cloud covered may occasionally reduce the accuracy of SST at these pixels. The accuracy of the DHW depends on both SST and the SST climatology used for deriving DHW.Related Questions

Since the primary error source in synthetic aperture radar data is speckle, which has the characteristics of random noise, combining data through averaging reduces the error by the square root of the number of data takes used. In the case of SRTM the number of data takes could range from a minimum of one (in a very few cases) up to as many as ten or more.Related Questions

Mount Rushmore National Memorial: Accuracy Assessment FAQ Me...The attributes for the accuracy assessment were recorded in the field in July and August, 1996. Vegetation associations were identified based on thefield key and plant identification. If additional communities were found within a 50 meter radius of the plot center, they were recorded as well. During the analysis, it was concluded that some attributes were in error and changed to match the mapped attributes. This was done by examination of the aerial photographs under stereoscopic view.Related Questions
What observations do you do ?
Wirral Hospital Trust - Frequently Asked QuestionsWe do what are known as baseline observations such as temperature, heart beat, breathing rates and blood pressure. These are recorded so that we can assess whether there is any deviation from the normal values. We listen for any noises that the baby makes whilst breathing. Obviously babies can cry!! But sometimes they can make a "grunting "type noise which can indicate that the baby has some distress with their breathing.
