Free Downloadable Satellite Charts (No Gimmicks!)
Last Updated: 02/19/2021

Here are the Satellite Charts I have made/collected for the areas we have visited in the Western Pacific, plus a few other chart sets that other people have done.  Be sure to read all the cautions and 'how to's' down below.  (Thanks to all those cruisers who have shared their Satellite charts with me that have been included in these sets).  Note, charts made before 2020 are KAP files, those 2020 and newer are mbtiles.

For WHY you want/need Satellite charts:  SSCA Presentation on Navigation Alternatives

These are ZIP files.  To save to your local hard drive, right-click on each file and select "Save As", and save to your Charts directory, then unzip them.  Instructions on how to "install" the charts for the most popular charting programs are below.

About Satellite Charts           Useful? Buy Us A Beer

DISCLAIMER DISCLAMER--these are homemade charts off Google Earth and other Satellite pictures. Don't trust your boat to these charts without lots of other corroborating evidence (other charts, your own eyes, depthsounders, etc).

The Satellite chart pictures are in general very accurate--usually more accurate than even the latest available charts we have in Tonga and Fiji and etc.

However, we know of a least 3 real issues possible with these 'home-made' charts.

1. Always always always do a cross reference between known waypoints before you trust any of these home-made charts.  And always back up this new-fangled technology with 'Mark I Eyeballs'

2. Any Satellite view sometimes has remote reefs 'missing' or painted out. Not sure why this is, but don't assume an empty expanse on a Satellite chart is really empty. Try to find S Minerva Reef, Rose Atoll, and Fonua One One (Tonga, S Vavau Group) on a GE chart. So again, always be cross-referencing with a regular chart when using these charts.

Note:  If you are using Google Earth, and the chart has clouds in it, or is "painted out" or lacks the normal Google Earth detail, it's worth taking a minute to check GoogleEarth again--they are continually updating the imagery.  Recommended:  Also try using SASPlanet and looking at alternative image collections (Ge2KAP now works with SASPlanet too)

3. In areas with small patch reefs, I have noticed that sometimes clouds form right over reeflets and small island. You think--"Oh, that's just a cloud.", but there's a good possibility of something solid underneath that cloud. (the reef warms the water and causes the small cloud, which obscures the reef in the sat pic). Always be suspicious of clouds.

Most of these charts were made with GE2KAP/Sat2Chart, a free utility available on the internet. Hundreds and hundreds of hours went into development of this tool. If you find them useful, go to the website and Paypal the author, Paul Higgins (a cruiser too) $10 or $20 to thank him for his incredible contribution to 'off the beaten path' cruising.

To Use with Maxsea 10.3.2.1

Put the chart folders where ever you want them to be. For example:

 C:\Charts\GoogleEarth\Fiji

To load the charts into Maxsea, click File / Open (NOT Open Chart)

Navigate to the folder where the charts are. Click on ANY KAP file (the individual chart files inside the folder), and click the Open button. Maxsea will load all the chart files in that folder. For multiple folders (ie Fiji, Vavau, etc), repeat for each folder.

These charts will now show up in a DIFFERENT window than the C-MAP (CM93) chart window that you are used to. To switch between windows, click Window on the main menu, and then either Raster or CM92Ed2.

Note that in Maxsea, these two windows are de-coupled. The routes will always show up in both windows, but the current view (ie zoomed in or zoomed out, etc) and the layer files are maintained independently. You can have a layer turned on for CM93 and not turned on for Raster and vice versa. You can be really zoomed in in Raster and zoomed out in CM93.

The only way I have found to remove chart loading in Maxsea is to shut down Maxsea, rename the folder to something else (temporarily), and start Maxsea back up.  Not finding the folder, it forgets about it permanently.

To use with Maxsea Time Zero

You are completely out of luck!  Furuno's Maxsea Time Zero product calls these 'legacy' charts.  They would much rather you buy charts from then than get them free off the internet.  You cannot use these charts with Maxsea Time Zero.  Their help files essentially say, you can keep your legacy version of Maxsea (or other charting program) installed along with Time Zero.

To use with OpenCPN

1. Copy this chart folder to someplace where you can find it again (My Documents\ or C:\Charts\ or whatever), and make sure it is unzipped

2. In the OpenCPN program, click the Wrench Icon, and click the Charts Tab

3. (v3.02 and below): In the upper part of the window, browse to where you put the Charts in step 1 above), and select one of the folders. You should see the full folder path in the box just below, something like this:

C:\Charts\GoogleEarth\GoogleEarth-Fiji\

(v3.1 and above):  Use the browse button to navigate to the folder and click the add button.

For lots more info on using OpenCPN, see our presentation we gave to SSCA in 2015

5. Click on the Add Selection button, and the folder, AND ALL SUB-FOLDERS will be added to the 'Active Chart Directories' box below. Do this for whatever charts you will plan to use in the near future.  If you end up with a multi-level folder structure (ie "Micronesia" and then a folder for each zip file, OpenCPN will find any chart in the tree, but Maxsea will only find the charts in the one folder you point it to).

6. Click OK, and OpenCPN will rebuild its list with your new charts included.

7. If you have 'chart quilting' turned on in OpenCPN, Play with the light blue bars at the bottom of the screen to see which level of chart you can choose.

To zoom in and out, the easiest way is with the + and - keys on your keyboard.
