Data_Set_Credit: Tompkins County ITS GIS Division. Building data outside the City of Ithaca originally vectorized by Hitachi Software. Original orthoimagery (Color Infrared) from the NYS Office of Cyber Security & Critical Infrastructure Coordination, 2002. City of Ithaca data originally produced by NYSEG and subsequently updated by the City of Ithaca Planning Department.
Native_Data_Set_Environment: Microsoft Windows Desktop 7 Professional Service Pack 1; ESRI ArcGIS 10.2.0.3348

Data_Quality_Information

Logical_Consistency_Report: All polygons in this dataset is part of an ArcGIS geodatabase and consistency is maintained using ArcGIS map topology and geodatabase topology rules, then exported to a shapefile. Error checking is performed in the source data set. Please keep in mind that this dataset is not field checked and as with any features extraction process there are going to be polygons that looked like buildings on an aerial photo but are not in the field.
Completeness_Report: Complete for the entire county.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report: Varies, depending on source of building footprint. The accuracy of the data set ranges from the accuracy of the 1991 Tompkins County Planimetric Base Map series data in the City to the accuracy of the 2002 aerial photos and later sources.

Process_Step:
Process_Description: In June of 2005, Tompkins County ITS GIS Division entered into a contractual service agreement with Hitachi Software to provide building footprint data from 2002 infrared Ortho Imagery using the Hitachi HouseDiff method. See <http://www.hgiis.com/services/serv_housediff.html> for more info on HouseDiff. The result of this contract was a shapefile of building footprints with 44,711 features received by Tompkins County on August 3, 2005. As spelled out in the contract Tompkins County had 30 days after receipt to review the building footprints for errors and to provide feedback to Hitachi Software before the deadline. This deadline was extended to September 30, 2005 via a letter from Hitachi Software received by Tompkins County on September 2, 2005. The two parties agreed that feedback would be provided in the form of a point shapefile consisting of two fields; "status" and "comment." The values for the "status" field are denoted in the enumerated domain values for the "status" field under the Entity Attribute section of the feedback point metadata. Comments were also added when necessary. The data was derived via manual inspection of each image tile from the countywide orthoimagery dataset with the exception of those tiles covering the City of Ithaca. Photographs were used by the Tompkins County review team to detect differences in shape and to help with missing buildings where applicable. The building dataset was processed by Hitachi on a parcel-by-parcel basis using 2002 County tax parcel data and original 1991-1995 Planimetric Building footprint data. Feedback (point shapefile) was sent to Hitachi, and a final building footprint dataset with changes from the feedback process was received on October 5, 2005. These buildings were manually inspected by grid to make sure that the buildings correlating to each feedback point were processed. The resulting data file was copied and merged with the buildings covering the City of Ithaca that are from the original 1991-1995 Planimetric building footprint data.
