Data Quality Information:


Attribute accuracy:
Attribute accuracy report:
Attaining 80% precision.  Trail surface length and average, minimum and maximum slope were calculated based on a TIN developed from the coverage dpg_topo.

Quantitative attribute accuracy assessment:
Attribute accuracy value: LENGTH_FEE
Attribute accuracy explanation:
This is the length of each trail segment in U.S. survey feet.  This is an precise number calculated using an ARCVIEW script called XTOOLS.

Quantitative attribute accuracy assessment:
Attribute accuracy value: LENGTH
Attribute accuracy explanation:
This is the length of each trail segment in U.S. survey feet but it differs slightly form the LENGTH_FEE field.  When the trails shapefile was converted to a coverage, it changed a field that was originally in miles to feet.  The miles were rounded to the nearest thousandth and when they were converted to feet it may have added some discrepancy between the LENGTH and the LENGTH_FEE fields.

Quantitative attribute accuracy assessment:
Attribute accuracy value: WIDTH
Attribute accuracy explanation:
This is the trail width in U.S. survey feet as measured by ocular estimation in the field.

Quantitative attribute accuracy assessment:
Attribute accuracy value: BUILDDATE
Attribute accuracy explanation:
This is the most recent known Date that a trail was either built or resurfaced.  Many of the trails do not have an exact BUILDDATE associated with them.  These are the records which are blank.

Quantitative attribute accuracy assessment:
Attribute accuracy value: ORIGCOST
Attribute accuracy explanation:
This is the cost associated with the most recent build or resurface.  Many records are not populated.

Quantitative attribute accuracy assessment:
Attribute accuracy value: AVG_SLOPE
Attribute accuracy explanation:
This is the average slope of each trail segment based on the elevation data from a TIN which was derived from the dpg_topo coverage.  It was calculated using an Avenue script called Surface Tools which can be found on the ESRI website.  It is only as precise as the TIN but it does provide some idea of the topography encompassed by the trail segment.

Quantitative attribute accuracy assessment:
Attribute accuracy value: MIN_SLOPE
Attribute accuracy explanation:
This is the minimum slope of each trail segment based on the elevation data from a TIN which was derived from the dpg_topo coverage.  It was calculated using an Avenue script called Surface Tools which can be found on the ESRI website.  It is only as precise as the TIN but it does provide some idea of the topography encompassed by the trail segment.

Quantitative attribute accuracy assessment:
Attribute accuracy value: MAX_SLOPE
Attribute accuracy explanation:
This is the maximum slope of each trail segment based on the elevation data from a TIN which was derived from the dpg_topo coverage.  It was calculated using an Avenue script called Surface Tools which can be found on the ESRI website.  It is only as precise as the TIN but it does provide some idea of the topography encompassed by the trail segment.

Quantitative attribute accuracy assessment:
Attribute accuracy value: TRAILID
Attribute accuracy explanation:
This is the unique alpha numeric identification used in an effort to better relate this attribute table with the work order database.

Positional accuracy:
Horizontal positional accuracy:
Horizontal positional accuracy report:
Of all the trail sgements, approximately 25% were taken from the field using GPS.  All GPS files were differentially corrected using Trimble Pathfinder Office 2.8.  They were corrected to have a horizontal accuracy so that features are within one meter of their actual location (sub-meter accuracy).  The remaining 75% of the trail segments were digitized "on-screen" using the 1998 DuPage County aerial imagery as a background.

Vertical positional accuracy:
Vertical positional accuracy report:
No Vertical data was collected.
