NOAA Integrated Ocean and Coastal Mapping provides 2.5km by 2.5km digital orthophoto mosaics with a 1-meter ground resolution. The mosaics are three-band, 8-bit GeoTIFFs covering Pensacola Bay and surrounding areas from Big Lagoon to Navaree Beach. NOAA's Coastal Mapping Program produced this data from aerial imagery captured on February 6-7, 2010.
Use Cases
- Analyze shoreline change over time by comparing the 1-meter resolution orthophoto mosaics with later imagery.
- Map coastal habitats like bays, islands, and tributaries using the uniform color-balanced GeoTIFF tiles.
- Perform land cover classification on the three-band, 8-bit imagery covering the project area from Big Lagoon to Navaree Beach.
- Validate or update nautical charts using the aerotriangulated and orthorectified mosaic tiles of Pensacola Bay.
- Support urban planning by assessing development near Escambia Bay and East Bay with the 1:30,000 nominal scale imagery.
Strengths
- Provides orthorectified mosaics with a nominal ground resolution of 1 meter.
- Coverage spans a defined project area from Big Lagoon to Navaree Beach, including multiple bays and islands.
- Data is processed as three-band, 8-bit GeoTIFFs with pyramids for efficient visualization.
Limitations
- Imagery is from a single acquisition date in February 2010, offering no temporal series.
- Specific technical details like row count, file size, and exact geographic bounds are not provided.
- The source film was captured at a scale of 1:30,000, which may limit detail for very fine feature analysis.
Provenance
- Source

- Collection Method
- Aerial imagery captured with a WILD camera on February 6-7, 2010, processed through aerotriangulation and orthorectification.
