H-GAC will provide a one-time copy of STAR*Map to the school's library or GIS lab for academic usage free of charge. Further updates would require the educational organization to purchase STAR*Map either via a one-time purchase or the annual subscription option. Any educational organization who receives a copy of the STAR*Map (paid or otherwise) does not have the right to share the STAR*Map database with any third party or other educational organization, and should restrict users from downloading the database. Students should contact their library or GIS lab to gain access to the STAR*Map database. Education organizations are required to abide by all STAR*Map licensing restrictions.

Star*Map may not be shared or resold outside your organization.
There is a field in the roads layer called "Road_Class" that you can use to symbolize the roads on the map. It is the field that we use to differentiate the different types of roads on a map. It is a very useful tool to display roads on your maps.
