Definition: Mapping unit

Category: Land Use/Land Cover

The mapping unit is the smallest area measured and mapped during the surveying. The size of this unit is first of all determined by the user requirement, in our case the scale of the map to be produced, or better to say the precision and accuracy required to identify the smallest objects to be mapped.  Secondly, the size of the unit depends on geometric precision or the spatial resolution determined by the data collection technique or the tool, which should be selected accordingly. http://ec.europa.eu/eurostat/ramon/statmanuals/files/KS-34-00-407-__-I-EN.pdf#page=84
