Abstract:
The 2000 Digital Terrain Model (DTM) Points layer contains 3D points with a known northing, easting, and elevation; for all of Summit County. This is an update to the 1994 DTM mass points data, originally compiled by Woolpert LLP from 1994 aerial photography. Kucera International, Inc. updated and error corrected DTM mass points data in areas of change indicated from aerial photography taken in April 2000. Delivery format was in ESRI ARC Generate ASCII text files tiled into 16 areas covering Summit County. Each ARC Generate file was converted to a "Z aware" point shapefile and appended, using ESRI ArcGIS 8.3 SP2, by Summit County GIS, to create this county-wide layer. This layer is part of a DTM dataset containing breakline and spot elevation data to be used together in the creation of accurate 3D surface representations (TIN, contours).
Purpose:
To provide the taxpayers and agencies of Summit County a 3D surface layer at a scale and accuracy useful for property appraisal, planning, and terrain analysis. These DTM data were also necessary to orthorectify the 2000 aerial photography and adjust distorted topographic data features derived from the photography. This dataset was compiled to National Map Accuracy Standards for a map scale of 1"=100' (1:1200) for those purposes. The suitability of this dataset for any other uses is not guaranteed and the user assumes all risk for such uses. Summit County, Ohio, assumes no legal responsibility for works derived from this dataset.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Attributes are accurate as determined from the source aerial photography and survey data from which they were compiled. The Surface Type attribute was calculated from the line definition in the original DTM Generate ASCII files. No field verification was performed.
Logical_Consistency_Report: Topology rules were not tested against this dataset.
Completeness_Report:
The completeness of the dataset reflects ground features interpretable from aerial photography and survey data at the time of photography: 1994, except in areas of change, which is 2000.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Dataset was compiled to National Map Accuracy Standards for 1"=100' (1:1200) scale maps from aerial photography; scale of negatives are 1"=800' for 1994 photography and 1"=660' for 2000 photography.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Dataset was compiled to National Map Accuracy Standards for two-foot contours.
