contrast etc.

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.
