Data_Set_Credit: Tompkins County ITS GIS Division. Building data outside the
City of Ithaca 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 XP Version 5.1 (Build 2600) Service Pack 2;
ESRI ArcCatalog 9.1.0.722
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 featureclass or shapefile for the entire County.
However, keep in mind that the City of Ithaca portion of this
dataset was not part of the Hitachi HouseDiff process which acquired
footprints from 2002 aerial photos.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report: Varies, depending on source of building footprint. The
accuracy of the data set range from the accuracy of the 1991
Tompkins County Planimetric Base Map series data in the City
to the accuracy of the 2002 aerial photos.
Lineage:
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.
