- The transportation information included
as part of the BaseMap has changed significantly. Previous
BaseMap information was offered as Arc/INFO coverages or
export files (.e00). With the new release files are offered
as ArcView shapefiles. Roads are no longer provided as separate
coverages for each road system; they are now presented as
a single shapefile containing all road systems. When available,
up to four road names, including 911 name, have been added
for each public road (no longer just trunk highways). Routes
which were previously offered for only the trunk highway
system, are now built for the entire road network. Finally,
FGDC-compliant metadata is provided for each individual
feature data set, rather than a general metadata file for
the entire BaseMap.
