State of Mississippi, orthophotography, imagery, raster, Mississippi, USA
The collection of aerial imagery and production of orthoimagery were executed to capture the existing ground conditions at a specific point in time for the purpose of GIS analysis.
Orthoimagery typically provides an accurate base for digitally representing geographic features upon which a GIS is built. The Mississippi Department of Environmental Quality is the lead public agency in the State of Mississippi for spatial data and GIS. The intent of MDEQ is to facilitate the cost-effective development and use of spatial data, GIS, and related technologies in organizations throughout the state.
In the Fall of 2023, the Mississippi Department of Environmental Quality (MDEQ) and Mississippi Geographic Information, LLC (MGI), contracted with SURDEX Corporation to acquire and produce full color (4-band) 6-inch GSD high resolution digital orthoimagery. The aerial imagery was acquired during the acceptable leaf-off flight season of early 2024 (01/13/2024-03/12/2024).
The Mississippi 2024 Orthoimagery project is the second year of three to update the orthoimagery for the entire state of Mississippi with 6-inch resolution imagery. The project is divided into three collection phases: In 2023, SURDEX acquired 16,087 square miles in the central third of the state that included 25 counties with 6-inch high resolution imagery. The area included the following Counties: Attala (736), Choctaw (418), Clarke (693), Hinds (877), Holmes
(764), Humphreys (431), Issaquena (439), Jasper (678), Kemper (767), Lauderdale (715),
Leake (585), Lowndes (517), Madison (742), Neshoba (572), Newton (579), Noxubee (700),
Oktibbeha (461), Rankin (806), Scott (610), Sharkey (435), Smith (637), Warren (618),
Washington (761), Winston (610), and Yazoo (934) Counties, Mississippi. In 2024, SURDEX acquired 16,081 square miles in the northern third of the state that included 30 counties with 6- inch high resolution imagery. The area included the following Counties: Alcorn (400), Benton (407), Bolivar (877), Calhoun (587), Carroll (628), Chickasaw (502), Clay (410), Coahoma
(552), DeSoto (476), Grenada (422), Itawamba (533), Lafayette (632), Lee (450), Leflore (593),
Marshall (706), Monroe (765), Montgomery (407), Panola (685), Pontotoc (498), Prentiss (415),

(424), Tunica (455), Union (416), Webster (421), and Yalobusha (467) Counties, Mississippi. In 2025, the remaining southern third of the state that includes 27 counties will be completed with 6-inch high resolution imagery. The Mississippi Orthoimagery Program will encompass the entire land area of the State of Mississippi over 3 years. The State boundary is buffered by 2,500'.
