3 inch imagery resolution for Washington, DC by Jacques Tardie.
From the post:
We updated our basemap in Washington, DC with aerial imagery at 3 inch (7.5 cm) resolution. The source data is openly licensed by DC.gov, thanks to the District’s open data initiative.
If you aren’t familiar with Mapbox, there is no time like the present!
If you are interested in the just the 3 inch resolution aerial imagery, see: http://opendata.dc.gov/datasets?keyword=imagery.
