Intended Use: For map display

Lineage: Created in December 2011 from dist_hist_footprints and dist_hist_SHPO_points

Supplemental Information: This data was built from access database of National Register structures from Arizona State Historic Preservation Office. The records from the SHPO database were geocoded. This point layer was extensively research in the spring and summer of 2009. Additional districts and geometry added in 2010-2011, and additional data researched and reorganized. Original maps, National Register Historic District documents' property lists, and change of status letters were used to verify the location and status of each record. The geometry of the footprints were originally derived from multiple sources. Manually digitized from 2008 aerial photography, conversion of layered pdf's to dwg's that were rubber sheeted to align with the 2008 aerials, pgdb or dwg's from the consultant, or raster to vector conversion of scanned hard copy maps for Sam Hughes N.R. District.

Use [HDReg_Status] field to determine if a structure is contributing to a National Register Historic District ("Contributor"). Use [ILReg_Status] field to determine if a structure is Individually Listed on the National Register of Historic Places ("Listed") or is Eligible to be listed ("Eligible"). Use [Reg_Status] field to determine the National Register status of a structure.

District. Status derived from dist_hist_SHPO_points. Use [Contributi] field to determine if a strcuture is a contributing to a National Register Historic District ("Yes"). Use [On_Register] field to determine if a structure is Individually Listed on the Register ("On_Reg") or is Eligible to be listed ("Eligible") Dec 2009 - loaded shapefile into EDITSDE geodatabase

(from original dist_hist_SHPO_point layer): This data was built from access database of National Register structures from Arizona State Historic Preservation Office. The records from the SHPO database were geocoded. This point layer was extensively research in the spring and summer of 2009. Original maps and National Register District documents property lists, and change of status letters were used to verify the location and status of each record. There are a number of records that could require additional research, the site survey form, to determine the location and or status. These records are identified in the [Status_QC] field with the attribute of "QQQ". Use [Reg_Status] field to determine the National Register status of a structure.
