General Discussion / Re: New Maps for Canada, US and Mexico
« Last post by sockmonkey on August 11, 2022, 05:03:30 PM »

It is fairly simple, though there is a specific process to follow.  It looks like you are interested in the CA-WestProvTopo.  I'm going to assume you are using Windows.  I'm not sure what version you downloaded already, but you you need to download the MAC version.  Yes, it is zipped but it is in standard zip format not 7z, as that's an allowed format to upload.  With whatever tool you use unzip that file and you should have a folder.  In that folder it is named CA-WestProvTopo you should have two folders inside that named, WestProvTopo and WestProvRouteable, both of these will end in .gmapi  Depending on your archive utility you will need to open that folder you desire one or two times until the end is just gmap.  (If you see Product1, etc you've gone too far and back up one step).

Go to C\ProgramData and make sure show hidden items is enabled.  You may see a folder named Garmin with a folder within named Maps, if not create them and you should end up with C\ProgramData\Garmin\Maps   Copy the folder ending in gmap to the Maps folder, now open Basecamp and this map should now be in your drop down on the toolbar and select it.

Now transferring to you GPS.  Since you are not necessarily interested in the whole mapset I suggest your install Garmin Mapsource https://www8.garmin.com/support/download_details.jsp?id=209). if you don't already have it.  I find it easier than basecamp to select smaller areas to install to the gps, not just my maps but also Garmins own maps or any other compatible maps for that matter.  Hope this helps!

First of the Canadian Topo maps is up.  This one includes the provinces of British Columbia, Alberta and Saskatchewan.

Hope I can get an answer here, hope its simple.

I dowloaded this map to my desktop, shows as a 7z zip file. I want to put it into Garmin Basecamp and load it onto my Montana 610.

I'm not getting it to load. Maybe I need an extra step to unzip it or something. Someone who knows the steps help me out please.

Don't really need Alberta and Saskatchewan, if there's a smaller file of BC and Vancouver Island

I've read the great tutorial about using Basecamp to  load maps to GPS receivers [https://www.gpsfiledepot.com/tutorials/how-to-load-maps-on-my-garmin-gps-unit].  In my case, using Montana 650T with SD card and US Topo 100K in ROM, the process behaves differently than indicated in the tutorial.  Especially annoying are:
1. When I add a new map, no matter what I choose, ALL the maps get re-written (painfully slowly). MapInstall goes through as many cycles of "Building MapSet"  as there are old maps plus the new one.  So "Leave as Is" selection seems to be ignored
2. The carefully_chosen_filenames.img of the existing maps are rewritten with defaults e.g. CO & UT GarmTopo24K.img (1.321GB) becomes  TOPO US 24K Southwest.img (1.321GB)

Or is this the typical experience?  Everything gets rewritten??

Version info:
Basecamp Windows 4.7.4
Latest Montana software version 7.60

Am planning to expand the map to a much larger area later this summer.

The new, expanded map is now available! This is the new coverage area - over twice the size of the original map, more than 600 gb with almost 22 million map tiles!  8)

Here's Shenandoah, Virginia in 3d


3d view of the Catskills


This is how it looks on a phone.

You can view the 3d map in 2d North-up mode if you prefer - just click the compass to toggle between 2d/3d. But there's a separate 2d version of the same map without the elevation data if you aren't interested in 3d views, it loads much faster (note that 3d maps appear in blue text in the map menu)

Here's the 2d map of Martha's Vineyard, for example.


I would like to continue expanding this map to cover an even larger area in the future. I still have over 200gb free disk space on the server but need to find the best use for it. Ultimately, I'll need to lease additional disk space to support future expansion.

It's not practical to create a map this large in one piece, so I divide it into smaller blocks of 100gb to 150gb of uncompressed 32-bit floating point DEM data. After processing this, I end up with blocks of a few hundred thousand .png map tiles which are ~1/4 the size of the source files. Then there is a companion set of .png tiles that contain the elevation data in Mapbox RGB format. The elevation tiles only use about half the space of the map tiles.

Before creating the RGB tiles, the geoTIFF DEM source file must be processed with Mapbox rasterio, which is a rather complex command-line program


This encodes the DEM data as a .tif raster image which can be exported as .png map tiles. It took awhile to figure out exactly how to do all of this, Mapbox does not really support creating your own RGB DEM, they expect you to use their own pre-packaged DEM. But their DEM is about 5-meter resolution and I wanted 1-meter DEM. Using their own content can also result in usage charges but it's free to use their API with your own data. But you're pretty much on your own, I could find very little information about how to implement all of this locally but eventually figured it out through trial and error.

I create all the the tiles with Globalmapper using the option to only export fully-covered tiles, this prevents gaps between different blocks of data when I merge them with the full map. Finally, I zip the tiles, upload them to the server and unzip.

There are so many steps to the process and so many different files, I had to create a spreadsheet to track my progress!
Using The Maps/Garmin Software / Re: Problem loading file on Garmin Oregon 450

You could try Mapsource, Garmin's older software. It was discontinued long ago but still available. Since you already have Basecamp, it should be easy - Mapsource should see the map that you have already installed. See this


And this


Using The Maps/Garmin Software / Problem loading file on Garmin Oregon 450
« Last post by ExploreNature on July 22, 2022, 06:08:12 AM »
Hi, my first post ever on your site.  Just joined.  I'm looking for free topo maps for kayaking.  I have an old Orgeon 450 I haven't used in years.
I downloaded the topo map of interest BUT....
When I connect my 450 to the PC, and open Garmin Basecamp which I just downloaded, I follow the instructions and run into a wall. 

I select Internal Storage, right click and select "Install map on Oregon 450", garmin Map Install opens automatically, it has already identified the Oregon as the device, it says "No unlocked maps were found for this device.", but "Continue" which is the next step is greyed out and if I click it, nothing happens.

Any ideas?  Thanks a lot for any help.

OK, just tried this on my DriveTrack and it lets me download Birdseye to the computer even though I no longer have an active subscription (same as always). When I try to send to the GPS, this is what I get - again, same as always.

But when I click the link to subscribe, this is what I get. Nice job Garmin. I was disillusioned about them before, but this is a new low.  >:(
