USGS High Resolution Orthoimagery for DuPage County, Illinois: 16TDM020275_201203_0x1500m_4B_1
Dataset Identification:
Resource Abstract:
"This file is a digital geospatial Environmental Systems Research Institute (Esri) ArcGIS polygon feature class of the tile
index for Cook, DuPage, Grundy, Kane, Kendall, Lake, McHenry, and Will County, Illinois. Each tile is 2,500' on a side, and
covers an area of 6,250,000 square feet or 143 acres. There are a total of 18,905 tiles, and each tile represents the boundary
or extent of each ortho image. This dataset includes a coordinate based tile identification number, a delivery area number,
and a project tile category. The delivery area numbers and project tile attributes are a proprietary classification that are
unique to this project. This dataset is stored within an ArcGIS 10.1 geodatabase. This dataset is projected using the Transverse
Mercator map projection. The grid coordinate system used is the Illinois State Plane Coordinate System, East Zone (Zone Number
Zone 3776, FIPS 1201), NAD 83 NSRS2007 (horizontal datum), with ground coordinates expressed in U.S. Survey Feet." An orthoimage
is remotely sensed image data in which displacement of features in the image caused by terrain relief and sensor orientation
have been mathematically removed. Orthoimagery combines the image characteristics of a photograph with the geometric qualities
of a map. There is no image overlap between adjacent files. Data received at Earth Resources Observation and Science Center
(EROS) were reprojected from: Projection: NAD_1983_HARN_StatePlane_Illinois_East_FIPS_1201 Resolution: 6 inch Type: 4 Band
to: Standard Product Projection: NAD_1983_UTM_Zone_16N Standard Product Resolution: 0.1500 m Rows: 10000 Columns: 10000 and
resampled to align to the U.S. National Grid (USNG) using The National Map. The naming convention is based on the U.S. National
Grid (USNG), taking the coordinates of the SW corner of the orthoimage. The metadata were imported and updated for display
through The National Map at http://nationalmap.gov/viewer.html Chip-level metadata are provided in HTML and XML format. Data
were compressed utilizing IAS software. The compression was JPEG2000 Lossy Compressed. The file format created was .jp2.

purpose:
"This data set was created to serve as part of a standard database for virtually all geospatial applications in Cook County,
and is intended to support general location, planning, and cartography projects, as well as general inventory and asset management,
Census analysis and mapping, and geocoding by address. The intended purpose of this Tile Index is to aid in the location of
the relevant ortho image that corresponds spatially with a particular polygon in the Tile Index." A digital orthoimage is
a geometrically accurate photographic record of landscape conditions at the time of the corresponding aerial photography.
As such, High Resolution Orthoimagery is useful for a variety of applications, such as environmental monitoring, facility
engineering/maintenance, city/county planning, property line review, etc. The digital orthoimage can be used alone or as a
raster basemap for corresponding vector line mapping. The detailed focus of High Resolution Orthoimagery provides emergency
responders critical information in determining the best evacuation routes, alternative routes and safe access to aid. High
Resolution Orthoimagery assists law enforcement personnel in determining the best locations to place surveillance cameras
in high-traffic urban areas and popular attractions. The data assists Federal, State and local emergency responders in planning
for homeland security efforts. This data also supports The National Map.

AbsoluteExternalPositionalAccuracy
name Of Measure Horizontal Positional Accuracy Report
evaluation Method Description
The relative accuracy is assembled by comparing rectified images generated from adjacent strips of imagery. The absolute accuracy
is assessed by measuring the ground control points in the rectified image against the actual surveyed co-ordinate position.
The testing is for overall accuracy. This data has been produced to be fully compliant with the National Map Accuracy Standards
(NMAS) for mapping at this scale.
AbsoluteExternalPositionalAccuracy
name Of Measure Vertical Positional Accuracy Report
evaluation Method Description
There is no vertical accuracy component to orthophotography.
