Updated Imagery Examples FMT for S. Florida

By popular demand :cool: , some updated samples below currently available on the latest S. FL chip by Florida Marine Tracks running on the Navico line. These are photos taken by a cell phone of the S. FL chip running on a Simrad Evo 12. They are very representative but they really do look clearer and more crisp on the units themselves as opposed to a photo of the screen. A similar example set for N. FL will be posted soon. Both S. FL and N. FL have been well received and this imagery shown below along with N. FL is still not fully complete and is being further improved for brightness and contrast/color and is scheduled to be fully complete this year.
Also, by popular demand, FMT is currently sourcing 2015 imagery just like this for Louisiana and it should be available in 2016 as a stand alone product. Track development and marker corrections have already begun in LA.

The RED is all of the current Track development.

One thing I always wish I would see whenever I look at any of the satellite map images is a date (even just the month/year) the image was created, especially in places where the sands/shoals shift.
Either way, some really nice maps!
Its easier said than done as there are about 20,500 images covering FL the way we have it sliced up. In most cases, imagery for a region is from the same mo./yr but sometimes for certain spots we take some images from a different date to insert. We have FL broken up in to about 50 Regions. When you move across the map it generally looks seamless on FMT because we focus to try to make that happen but the GPS has no ability to read the dates on images that are in the view screen and change automatically. If you zoom out to see all of the Everglades it looks like one photo but the dates of some of the numerous images comprising that total area are different. We replace some images with others to get the best read and clarity we can find. For instance the entrance to Rogers River in 10000 islands is a different date from most of the rest of the river itself as it was the best image. The photos of Flamingo Marina and north into the everglades swamps are probably a year older than the images of Snake Bight adjacent to it.
The FMT imagery is all relatively recent with a lot of it being within approximately 12 to 24 months. Compare to Garmin or Navionics which has very dated poor quality lower res images that are about 10 yrs old, no substantive tracks, markers locations that are all off from actual positions, and no State Park markers or signs. FMT imagery is so detailed at 6" to 1' that only 1/2 of FL takes up about 25 GB of space on a chip. The resolution available to view is higher than the current technology available in the gps machines will actually display but as the technology improves to read even higher res, so will the appearance of those images in the updated machines and that is why it was programmed like that.
