The resolvability of features for a given map scale. Scale effects resolution. In a larger scale map, the resolution of features more closely matches real-world features because the extent of reduction from ground to map is less. Map resolution may refer to a "minimum mapping unit" or the accuracy at which a given map scale can depict the location and shape of map features. ESRI, 1994; Lund 1995
One meaning of the term 'resolution is the process of separating something into its constituent parts. The term is used in this project to refer to the scale of maps and field search units, and to the balance of cost and detail (i.e., the identification of constituent parts) that accompanies maps and units of different scale. For instance, as the scale of a map or the size of a surveyed land parcel becomes larger, finer-scale environmental detail becomes lost. As a result, the gross environmental associations that can be measured may obscure finer-scale " environmental/archaeological resource present" associations. The use of maps and units of high resolution are often precluded, however, by cost and the absence of maps at that level of resolution. High resolution models are necessary when the goal is to predict the precise locations of archaeological resources.
