Full credit for the spatial aspect of this data set should be given to MARIS.
Attribute values were validated via cross-checks with exisiting data resources including photographs, maps, imagery, and scientific reports.
All line work is checked for topological integrity and to ensure that polygons are fully enclosed, no duplicate lines or points exists, line segments are composed of sequentially numbered coordinate pairs, intersecting lines are separated by a node, and no dangling lines exist. Topological checks and strucuturing are performed using the ArcInfo software. Data dictionary specification are automatically implemented via the ESRI Info database management software. Data collected from external data providers are randomly verified.
The data are complete with respect to the data publication date and scale.
Feature locations were were validated via cross-checks with exisiting data resources including photographs, maps, imagery, and scientific reports.

Imagery used to align the vector placement of highways. NAIP from 2007 - 2009 was used in creation of original linework. Imagery was 2007 NAIP - 1 meter, 2009 NAIP - 1 meter ortho-rectified.
MS Coordinating Council for Remote Sensing and Geographic Information Systems (MCCRSGIS) 2006 2 foot resolution leaf-off imagery was also used for alignment of highways.
The highway database was collected by heads-up digitization over aerial photography. Aerial Photography sources are MDEM and NAIP. Digital and hard copy sources are listed in Source Information "Other Sources".
