Maps for my Garmin GPS

Updated 12-15-2007

There are some areas that I wanted downloadable maps for, but what was available commercially didn't have the detail that I needed.  Then I ran across the Keen People web site and it had a tutorial on how to make your own downloadable GPS maps for the Garmin units.  Below are my first Map attempts.  You will need Garmin's Mapsource  or the Shareware program, sendMap, to download these maps in your GPS.  Only Garmin GPS units that support downloadable maps will work.  These maps have been loaded on a Vista, Legend and 60cs (they look great in color!) without any problem.  Read about how to install these maps before you consider downloading them.  Here's the readme file. Garmin has no affiliation with these maps nor has any commercial data been used to create them.

All of my map sets may be installed in the same directory without conflict.

As far as what I map...I map places that I have been to frequently enough to justify and do not have a decent map for my GPS.

Now for the disclaimer:  You take any and all responsibility for any damage, Earth quakes or locus swarms caused by the use of these maps.  These maps are for entertainment use only.  Never rely on one navigational aid.  If you don't know how to use a compass and map, please learn that first and carry both with you.

Here's one map set that contains all of the maps below plus others that are not available individually.  The maps in this combined set are the most up-to-date. Not all of the maps contained in the set are displayed on this page

NOTICE: Due to the hurricanes of 2004 Ft. DeSoto has changed considerably.   As soon as I'm able I will attempt to map the new shoreline with GPS tracks.  I expect Egmont Key has shifted its shore also.

Egmont Key Preserve with trails and major historical features labeled.  Ft DeSoto needs the bike trail added, but is generally complete.

I visited this preserve in 2003 and was impressed at all of the quarry lakes and trails. It was my first attempt at map making.  It held up well when I went back with the map and followed some trails and walked the coastline of a few lakes.  

Of course, the lake sizes change quite a bit after heavy rains and during drought periods.

NOTE: This does not include the Weeki Wachee River, yet anyway

Here's the Weeki Wachee Preserve map as of 4-20-2004.  There are 2,150 points making it up.

This map was was an act of desperation. I was on a quest to finish the Going For Distance Geocache and this preserve was huge.  From the parking area it's 2 miles until you get to the real trails.  I couldn't find any maps that covered the bike trails, so armed with my Weeki Wachee Preserve experience I mapped it. I'm in the process of upgrading all of the lakes to higher resolution boundaries.  The quarry roads to the East are in the map but are not part of the preserve (not shown in the small image).  The quarry area is eventually going to be used for water storage and it isn't part of the Balm-Boyette trails.

NOTE: Most, but not all of the trails have been confirmed.

This is the Balm-Boyette Preserve map as of 4-20-2004.  There are 2,263 points making it up.

Weeden Island is one of the few nearly natural parts of Pinellas County that remains.  It has a series of boardwalks, a nature center and a canoe/kayak launch.  The latter is the start of a four hour kayak trail that tunnels through Mangroves from Papy's Bayou to Tampa Bay and continues around much of the island.  Parking and restrooms and water fountains are available.

This map was born out of the need for a detailed river map for some eventual canoeing or kayaking.  Additionally, I wanted to be able to add oyster an sand bars, etc.  I also have five Geocaches hidden in the area covered by this map. 

The The map now covers the Homosassa and Little Homosassa Rivers from the main spring to the Gulf.  Some detail and the background will be added.  I also hope to add some of the channel markers as soon as I get a clear day and some good numbers.

This is a complex map with about 10' resolution.  It's a little sluggish on the older units like the eTrex especially if you're zoomed way out.   It kicks butt on the newer units like the 60cs.  Even at the slower redraw speeds, it worth it if you need the detail.

The Hurricanes of 2004 may have altered some of the islands.  The Terra Server data used for these maps was taken before the storms.

The version in the combined map set contains more data than this version.

This is a beautiful river with minimal development on it.  After I got the kayak I decided that this would be one of my destinations and a better map than I had was needed.  I'll be refining this as time goes on with the goal of connecting it to the Homosassa Map.  For now, it takes you from the boat launce parking lot to the Gulf with plenty of side trips.
