    Watch for emails!

  • Click to edit Master title styleClick to edit Master title styleLicensing Reminders

    • License covers all current and past DRAPP imagery that you are using.

    • Term begins as soon as the license is signed and continues as long as you are using a DRAPP imagery dataset. Letter of Intent solidifies commitment for the current project and specifies funding contribution (not the license agreement).

    • Latest/current imagery: • Can be used for your internal business needs

    • Can be served up as a basemap in your webmaps

    • Can be provided to a contractor that is officially working for you and has signed an agreement stating they will only use the imagery for your project.

    • Can NOT be given away (DRCOG’s resellers sell the tiles and WMS)

    • Past imagery: • All of the above except tiles can be given away (to anyone including your

    contractors) with no written agreement

    • You may never sell the imagery because DRCOG does via our resellers.
