Data Preparation Original # Records in D10 = 6,546 (100%) Step 1: Data Processing
Tabular Information Problems (28% reduction) Narrowing Acceptable parameters (additional
21% reduction) Step 2: Linkage to GIS (additional 17%
reduction) GIS Mapping Route ≠ ODOT Highway Number
Final Data set totals 2,184 records (33% of total)
