The process of including subjects in the NSDI is happening in accordance with the diagram shown. Thus, the NSDI Act defines who and how becomes a NSDI subject, and the same Act establishes the Register of NSDI Subjects and the Register of NSDI Spatial Data Sources. The Register of NSDI Subjects gathers basic information about the subject as well as reported sources. The Register of NSDI Spatial Data Sources is a list of reported sources, with general information about them. The sources are described in more detail in the NSDI Metadata Catalog, which is an integral part of the NSDI Geoportal.
In addition to the Guidelines for filling in the Registers, the forms of the Registers the subjects fill in have been updated and then they submit them to the State Geodetic Administration. The form for the Register of NSDI Subjects is available at the link form Register of Subjects, and the form for the Register of NSDI Spatial Data Sources is available at the link form Register of Spatial Data Sources. On the NSDI website access to the Guidelines and forms can be found in the NSDI Documents category.
