Cross-MSDI Relationships

The Structures and Addresses database relates to the following other MSDI framework themes:

• Transportation—Structure/address points are often developed in conjunction with, and possibly based on, road centerline datasets with address range attributes.

• Administrative Boundaries—The addressing authorities in Montana are mostly county governments, with some cities, towns and tribal governments assigning addresses within their administrative boundaries. As such, administrative boundaries often depict the addressing authority boundary.

• Geographic Names—The structure/address point feature class contains NAME and GNIS_ID attributes. In cases where a structure or addressed landmark has a name contained in the GNIS, that name and associated GNIS feature identifier are included. Examples include Police and Fire stations, schools, churches, courthouses, and others.

• Orthoimagery—Current orthoimagery are a critical base layer for creating and maintaining structure and address points. Often, points can be located more accurately with imagery than with GPS.

• Cadastral—The structure/address point feature class contains a PARCELID attribute and the OwnerParcel feature class is often referenced for creating and maintaining structure points. In fact, many of the non-local government provided structures data were developed using cadastral data.

• Address Geocoding Web Service—The address geocoding web service is based on a composite address locator
