Mobile County, Alabama requires accurate data to effectively plan and manage county infrastructure. This dataset was developed to support those efforts for Mobile County. The Mobile County project area is approximately 1402 square miles. The project scope of work required the acquisition and processing of digital imagery in support of the development of digital color orthophotography at a six inch pixel resolution. Digital imagery acquisition was completed between 13th March through 25th March, 2014.  All deliverables were required to meet or exceed ASPRS Class II Standards for 1”=100’ or 1" = 200' scale planimetric mapping.

In 2020-2021, the following planimetric features were updated in 2D by The Atlantic Group:

Bridges
Buildings
Paved Parking Areas
Edges of Paved Roads
Railroads
Sidewalks - outside edges for incorporated areas; centerline for unincorporated areas
Swamps
Waterbodies

Updates were performed by comparing the current features with three inch resolution ortho-rectified aerial imagery collected in 2019 for the eastern half of the County and in 2020 for the western half of the County. Digital imagery acquisition was completed between 16th January through 13th February, 2019, and 4th February through 7th March, 2020. Imagery for the planimetric updates was shared by the Mobile County Revenue Commission.
