decimetersnivå

Decimetersnivå is a term used in Swedish technical and scientific contexts to describe data, measurements, or resolutions that are on the decimeter scale. A decimeter equals 0.1 meters, so decimetersnivå denotes a granularity or precision of approximately one-tenth of a meter. The concept sits between meter-level detail and centimeter-level detail and is commonly employed when finer detail than a meter is needed but finer precision than centimeters is not required.

In practice, decimetersnivå is most visible in spatial data and modeling. It is often used for gridded datasets such as digital elevation models or surface models where the grid cell size is 0.1 m, enabling moderate detail in terrain representation, surface contours, and small-surface features. It is also relevant in point-cloud processing, where data can be aggregated or resampled to a 0.1 m resolution to balance detail with file size and processing demands.

Data acquisition methods that can support decimeter-level resolution include LiDAR surveys, UAV-based photogrammetry, and high-precision GNSS measurements, though actual positional accuracy depends on data quality and processing workflows. Decimetersnivå is typically chosen when workflow efficiency, processing capacity, or project scope makes centimeter-level detail unnecessary, while meter-level data would be too coarse for the intended analyses.

Limitations include larger file sizes than coarser resolutions and potential alignment or interpolation errors when integrating datasets from different sources. See also decimeter, spatial resolution, digital elevation model, LiDAR.
