Florida Marine Tracks / ISLA Mapping

Florida Marine Tracks / ISLA Mapping Florida Marine Tracks LLC (FMT), a Navico Inc. Using FMT requires great attention to detail. It is not for recommended amateurs or novice shallow water boaters.

ISLA Mapping provides thousands of miles of precisely drawn marine navigation tracks on the most detailed and accurate map available anywhere along with unsurpassed super hi-resolution color aerial imagery for GPS chart plotters. mapping partner provides detailed marine cartography available on SDHC and micro chips for all of Florida for use in Navico chart plotters including Simrad, Lowrance, and

B&G units. FMT is unique among the current market of available mapping chips in that it provides 1) the highest quality and most recent ortho-rectified aerial color photography available in the market and it is specially enhanced for brightness and color helpful for use on the water , 2) thousands of miles precisely drawn detailed navigation tracks that were run at low tide suitable for flats and bay boats and other watercraft that can run in the shallows, and 3) a base map that is corrected to provide the current exact location of navigation aids including Daymarkers, Buoys, Signs as well as other mapping vector components that are missing on other products such as numerous signs, posts, concrete abutments and even many PVC stakes. By way of comparison, no competitor currently offers 1) imagery that comes even remotely close the overall quality that FMT provides, 2) detailed navigation tracks, or 3) navigation aides corrected for actual positions. It was developed and tested over many years and designed exclusively for smaller and shallow running flats and bay boats that draft 13.5" or less at rest. The quality of the FMT imagery is unsurpassed and in its raw state offers resolution at as high as 6 inches and in one area as high as 3 inches. All of Everglades National Park is covered at 6” and most of the rest of S. FL covered at 1’ or better. These high quality images provide resolution at a level that surpasses the ability of the most recent chart plotters to fully interpret as most units can read imagery down to approximately 3 feet. Thus, as the units become more capable in this regard we expect the photos FMT provides will become even clearer and that is why we elected to provide the imagery at its full resolution on the chips. The accuracy of the inshore location of the navigational aides is unsurpassed and we endeavored to correct them to the accuracy of 1’ so if you see a marker or a sign on the map you can rest assured it is exactly at that location (and if not, there was one there very recently). If you are frustrated with your dingy, fuzzy, dated, black and white, and missing chart plotter imagery you are sure to be much happier running with FMT. If you seek some direction on how to get from point A to point B and want a plethora of alternatives at a glance you will really appreciate FMT as it is extremely comprehensive. If you wish you could rely more on your chart plotter to get more situational awareness of the shallows around you in the back country to find new fishing areas, FMT provides this detailed insight as you can see much of what of what is around you in the water in the imagery. FMT even provides all of the Everglades National Park markers noted and placed on the map in their exact locations and a lot of PVC stakes too to help in navigating. If you are new to an area and have no idea where to run, you can run with FMT like a local pro. There are tons of proven shortcuts and tight runs but they do require great attention to detail to negotiate. FMT is not for the faint of heart but for those with a penchant for exploring challenging areas, it will successfully guide you in the shallows. Just ask any of our experienced FMT users. FMT chips currently run only on the Navico line of chart plotters but we hope to include other manufacturers soon.

ISLA has added approximately 2,000 new customers over the last year many of whom are also new to Florida. By the end of this year, we are on track to having delivered about 16,000 charts into the market over approximately the last decade. Interest in our unique charts continues to magnify in an exponential way. We have a wide range of users from recreational boaters, to travelling weekend warriors, to lobster and scallop hunters, and hundreds of the best professional charter captains. About half of our users are Garmin converts and that pattern has remained consistent over the years. We continue to convert about 1,000 Garmin users every year who tell us they are switching because their Garmin map fails them. We get it. Years ago, it failed us as well and essentially that experience we had with the Garmin charts and the failure of Garmin to even acknowledge a single shortcoming in their chart when we called them for help was the genesis of the ISLA charts. We had no intention at that time of making any maps. We asked them to fix it. They told us their map was the best in the market as it was, we were the only guys complaining about it, and if we could show them something better they might entertain further discussion about it. That was the beginning of FMT years ago.

Because our chart product is highly unique and very different from the other charting products in the market and because it solved the boating and navigational issues for our users in such a substantive way, most were very surprised when they first started using it. FMT gets people talking. FMT’s popularity has not grown just because it has highly detailed Tracks. Although the Tracks are highly popular, FMT is really a combination of the Tracks with the High-Resolution Images and the accuracy of the other unique fine details we provide such as PVC stakes, local buoys and signs and posts. Our imagery is regarded as the best available image data set for Florida in the world. No other GPS chart has image quality and consistency close to what we provide because all of our imagery is completely unique being hand adjusted for quality/professional presentation, color, brightness, and contrast. When all of that detail comes to life for the first time on a boater’s console after that boater has used the general reference map products for so long, it can become personal. Many say FMT was the best money they ever spent and their boating and navigational issues are finally solved. They enthusiastically sell FMT charts to their boating friends. We are very appreciative of our users who also appreciate the work we do; they are our best advertising.

With so many new users coming into the FMT family of boaters in the last few years, we are fielding an increasing number of questions every month from users who are curious about the genesis of ISLA and how we do what we do. FMT changed the boating and fishing experience of so many in such a meaningful and personal way they are calling us to inquire how we did it. We are happy to tell the story but it is quite a long story to tell..

To this end, over the years, ISLA has done a few Podcasts which summarize the ISLA/FMT story and they are linked on our website ISLAmapping.com in the Press/Video section. The most comprehensive and insightful podcast was hosted by Dave Le Gear who runs the popular FlatsNation.com website where he has a number of podcast recordings that are relevant to all inshore boaters among a lot of other interesting articles, cool gear and photos. If you are an ISLA/FMT user, you owe it to yourself to check out FlatsNation.com.

If you are interested to learn more about ISLA, the entire story can be listened to at the link below on Dave’s site. It runs for more than 3 hours so if you are inclined to hear the story, it’s intriguing listening on a long car ride. https://www.youtube.com/watch?v=7JirK5KbxOo

We have wrapped up our trip to the Pine Island area. Over 3 consecutive days we ran nearly 400 miles covering water from south Estero Bay to south Venice. I estimate about 1750 edits have been made to the chart consisting primarily of daymarker, buoy and sign changes. Lots of buoys were moved or added. Lots of signs were added or moved. All of the missing daymarkers were added back and some moved a little from their former locations. Many of the hurricane obstacles were removed. A plethora of pvc stakes were added primarily near sensitive seagrass areas. We found only a few track changes. The track at Blind Pass changed a lot due to the shifting bar and the track at Milton Pass which was around since the last hurricane is now totally closed off and back to a full beach so that track is being removed.
Milton Pass is no more reported closed off by natural means about 90 days ago.

The updates are scheduled to start shipping next Tuesday. All updates must be ordered at the website store where it says Update my Chart. Detailed directions are posted there for updates. Don’t know how old your chip is to complete your order? Call the shipping hotline # for the answer.

It looks official. Milton Pass is Closed. We just updated Our NFL chart with the post storm imagery showing the new pass and the route through. It appears the area was heavily dredged and filled back in (until the next big storm). But the locals say the area closed back up naturally and filled all the way in about April of this year. This track will be removed next week along with about 2,000 other edits on the chart to a large variety of map features in the Pine Island area.

This week we have run more than 200 miles from the Estero Bay Area to the north end of Pine Island checking stakes, markers and buoys, and obstacles. Most of the hurricane obstacles are now gone and will be removed. Virtually all of the missing markers have been replaced and lots of signs moved around. Some of the replaced markers were put back exactly where they used to be and some moved. Numerous buoys have moved and/or were added with many added by the county along the beach in the Gulf from Redfish Pass all the way to Bonita Springs. Some new stakes popped up in the sound as well. The rest of the week we will run north towards charlotte harbor, Boca grand and Lemon Bay.

The sale was just announced. If its not immediately reflected on our website it will be this week or you can call our shipping hotline to have the price immediately adjusted according to the advertised pricing.

ISLA will be in the Pine Island/Sanibel area rerunning the areas between Lemon Bay and Estero Bay next week. We will be endeavoring to check all of the replaced markers, signs and buoys and completed construction. If there is a specific spot or issue you believe we should address on our chart please let us know the exact coordinates so we can take a look.

Running a Raymarine Axiom inside Marquesas. The touch only design is not optimal for our chart but we managed it ok. Would have been much easier with Pro2 axiom which is not touch only and has a k**b to zoom.
Our gps took us to several permit spots.
