I'm looking for somewhere I can get aerial map files for exclusive offline use. Essentially I need aerial files (JP2K, GeoTIFF, etc.) that can be purchased or acquired and hosted on a private offline server.

I have used NAIP aerial files in a past and they have worked great but they don't have coverage in the area I am interested in. I need the files to have at least the equivalent resolution as NAIP. It also can't be a subscription service it needs to be a one time payment to acquire the files that I need.

Preferred resolution is equivalent to NAIP so 1-meter ground sample distance (GSD), I would like the files to be <5 years old but that can be a little flexible, and the area of interest is Aberdeen Proving Grounds outside of Baltimore.

    Could you expand on which area you need, which resolution would be preferred, how old the data can be and what channels you are interested in?

  • Thanks for the reply Erik, I've expanded my question but am not sure what you mean by channels?

    Channels = color bands (Red, Green, Blue, Near IR, etc)

  • NAIP should have wall to wall coverage in the US. What areas do you need coverage?

The State of Maryland has leaf-off orthoimagery available for download for no cost that is refreshed on a regular cycle. See https://imap.maryland.gov/Pages/imagery-download.aspx for more information. It will be higher resolution than NAIP. \

  • Lots of other states do as well... Dec 11, 2018 at 20:54
