In order to accommodate the needs of cultural resource managers and gain the most benefit from integrating cultural resource data, the cultural resource spatial data standards address two aspects of cultural resource data: the lineage of the data (feature level metadata), and the physical parameters of the spatial data.
- Metadata records necessary information that describes where the data originated, how it originated, who created it and other critical information needed to asses the data utility for any one specific task
- Physical parameters of the data include items such as coordinate systems, datums, levels of accuracy, etc., that insure that the data can be shared and combined correctly with other data sources
- Because cultural resource specialists have been collecting spatial data for their resources for many years, using many different methods, documenting how each point, line or polygon was created becomes important when combining cultural resource spatial data together for a single park, region or program
- Although the cultural resource spatial data standards focus primarily on feature level metadata, the standards do address several key data parameters such as the need to create spatial data (points, lines or polygons), specifying levels of data accuracy, and specifying a coordinate system and datum that spatial data should be created in
