Data drives the critical decisions we make every day. The Iowa Department of Transportation has long been a leader in the collection of transportation data, including things like traffic volumes, lane width, and sufficiency ratings. Many custom data systems have been developed by or for us that use the latitude and longitude of the centerlines of every public roadway to give a common linear reference point to tie together many types of data.
These systems, most notably the Geographic Information Management System (GIMS), provided access to a variety of information, but were sometimes complex to use and required a desktop application to access the data.
