There are two active Landsat satellites (Landsat 7 and Landsat 8), which make nearly direct overhead passes of Lake Okeechobee every 16 days at approximately 11:45 a.m. Their orbits are evenly staggered so that one of the satellites passes every 8 days, taking an image of the entire lake. Seven days after each overhead pass, each Landsat satellite also images the western portion of the lake. Those images usually will not be included here. Landsat 7 has a broken instrument which causes black lines to appear on the imagery.
The Terra, Aqua and Suomi satellites take lower resolution imagery of the entire planet each day. Terra typically makes its highest daylight "imagery" pass over Lake Okeechobee from North to South between 11:00 am and 1:00 pm. daily. Aqua and Suomi typically make their highest daylight passes over Lake Okeechobee from South to North between 2:00 pm and 3:30 pm daily. The angle of these satellites in relation to Lake Okeechobee varies greatly each day on the “imagery pass”. Thus, the quality of the imagery will vary, as will the amount of haze and sunlight reflection. Because Aqua and Suomi pass later in the afternoon, fewer of those images are included on this page due to afternoon thunderstorms blocking the view of the lake.
Landsat 7 and 8 images (30m resolution) will be posted here periodically depending on quality, availability and presence of algae. The second link below will actively retreive the past 7 days of images (250m resolution) from the Terra, Aqua and Suomi satellites directly from the NASA image servers.
