Using The Maps/Garmin Software / Re: lost tracks
« on: December 05, 2019, 08:22:09 AM »
Glad you figured it out.

I'm awake, but I really don't use Basecamp for anything these days. I always preferred Mapsource for managing tracks and waypoints, but the newer Garmin devices are a bit more complicated to use with it since they store data across a bunch of different .gpx files.

Personally, I always save .gpx files of all my important data, either as copies of the files from the device itself or compilations that I export from Basecamp or Mapsource. I would not trust Basecamp with all my data.

I wasn't 100% sure how Basecamp handles all this, so I didn't respond. I'm not surpirised that nobody else responded either, this forum is primarily for support of the maps on this site.

But you are right.... this forum is a sleepy place and so is GPSReview and GPSPassion. Happy 2020!  ;D

GPSr Units / Re: Garmin GPSMap 76CSx
« on: November 29, 2019, 09:11:28 AM »
BTW, since you're going to Spain... are you familiar with TwoNav? They are based in Spain and make some pretty cool dedicated GPS units and apps for all platforms. I am thinking about buying one of their handheld GPS units to replace my broken Garmin Montana. The map formats are not compatible with Garmin - which is fine with me, since I make my own maps anyway. But TwoNav supports several open-source formats and is not "locked down" in the same way as Garmin devices. There are lots of maps available for the EU, and openstreetmap and TomTom for the US. Their CompeGPS Land software for Mac/Windows is also very nice and lets you import/export maps in a variety of formats.

https://www.twonav.com/en/

They are having a Black Friday sale through the weekend, am trying to decide whether to pull the trigger on their Trail2 handheld. :) Anyway, you might check them out, as they should have excellent map options for Spain. If you look in the outlet section of their website, they have some older devices at very nice prices - even under $200.

The 76csx is the same hardware as the 60csx, which is one of Garmin's most popular models ever. The only difference is that the 76 floats and the antenna is located inside the case. I still have my 60csx, but don't use it anymore. I think the screen resolution is too low and processor too slow for a modern device, but others still seem to be happy with it.

Why do you think that Garmin doesn't make maps for it anymore? AFAIK, it will work with any of Garmin's maps as long as you have the newest firmware installed on it. Just about any of the maps on this site should also work on it - give it a try. It is not compatible with raster imagery however - such as Birdseye or "Custom Maps" (.kmz files).

So, I think it's really up to you as to whether ~20 year old technology is acceptable. Try loading some maps on it and using it before your trip.

Map Making Support / Re: looking for a way to make an overlay

Looks good!  8)

Sad story about the author of the Javawa software, he had a stroke a couple years ago and although he recovered, he says he just can't write software anymore. It's really too bad, because his stuff is great.

BTW, if you have a Mac that's capable of running older operating systems, you might want to set it up for dual booting. There are a variety of ways to do this, like using an external SSD with the older system on it. I have over $5000 of specialized legacy software that I don't use much, but still need. I can boot my 2012 Mini Server into Mountain Lion when I need it.

These two simple programs can convert a .gpx file into a Garmin .img file overlay, maybe they can do what you want? The first one is free:

http://www.javawa.nl/imgfromgpx_en.html
https://www.gpx2img.com

If you want to do something fancier, there's Mapwel, but it isn't free

https://www.mapwel.net

Or you could use cgpsmapper and a variety of other free tools, but that is more complicated. Sorry, I don't use the OSM tools.

Haha... Garmin is still living in the 1990's in some respects. With 2020 just around the corner, they really need to get beyond FAT32. Their own City Navigator EU map will no longer fit into a 4gb file and has to be broken into two pieces. And there are a number of things about their map format itself that really should be modernized. But as long as they can keep it working, there's not much incentive to make big changes - especially when they would lose compatibility with their old devices.

Anyway... you should be aware that there's another serious limitation that can bite you when installing multipe maps. Your device has a map segment limit - segments are the smaller tiles that make up the whole map.

https://support.garmin.com/en-US/?faq=Sf7jHKwP2V53j6MoP8AeH8

If you install more than 3000 segments, you will have problems with some of the maps. The results are not consistent, and depend on the exact maps you install. There are no standard sizes for segments, they could cover a whole state or just one county. But, typically speaking, you will hit the map segment limit by the time you fill up a 4gb SD card. So "bigger is better" is not really true when choosing SD cards for a Garmin GPS. An 8gb or 16gb card will give you more space than you can actually use for garmin maps.

There are several ways to check your segment count IIRC. Javawa's free device manager program should do it, and is also handy for other things

Wow! Garmin actually updated Basecamp? If so... good for them! Took them a long time, but at least they fiinally fixed this major problem.

General Discussion / Re: Convert a Garmin img file to GPX

There's no simple way to permanently install this kind of map on your computer. However, you can simply copy the entire contents of your Montana to a USB flash drive. Basecamp will treat that flash drive exactly the same as the real GPS. Or if you computer has an SD card slot, you could copy the Montana to that.

Now, on the Macintosh you could use Disk Utility to make a disk image of the Montana and that would also be treated exactly the same as the real Montana. Windows does not have a comparable program, but you could use a RAM Disk program.

Have a look at this: http://www.javawa.nl/virtualdevice.html

The same site also has some other excellent free software that every Garmin owner should have - specifically Javawa Device Manager and GMTK.

It's pretty hard to help when you don't say *how* you tried installing the maps. ;)

But if you're using the Windows version of Basecamp/MapInstall, then that is the problem. It doesn't work anymore with most of the maps on this site. And Garmin has discontinued Basecamp, so this will never be fixed.

See this thread for possible work-arounds/solutions: https://forums.gpsfiledepot.com/index.php?topic=4539.0

But, to cut to the chase.... use Mapsource instead of Basecamp with your 60csx. That is the software it was designed to use, and it still works.

Current basecamp 4.7.0 will not show an elevation graph on a route prepared on a DEM enhanced map (Talky toaster).

What does "DEM enhanced" mean? Garmin has never revealed their DEM format, and it has been a mystery to third party mapmakers for many years. Within the past couple years, somebody has finally "cracked" the format and come up with rudimentary tools for putting DEM into third party maps. I looked at this about a year ago and it appeared very complicated and also limited as to the format and resolution of the DEM, so I didn't try implementing it in my own maps.

Are you sure that TalkyToaster is really including Garmin-compatible DEM in their maps? The message  "this map has no elevation data" implies that the map does not really contain Garmin-compatible DEM. Regardless, I'd say that you do "have to put up with these restrictions".  :(  Garmin has discontinued Basecamp and there will be no further updates. "It is what it is".

And Garmin added a final insult to third party mapmakers. Old-style registry-format maps will no loger work correctly - they look fine in Basecamp but the data is not transferred to the GPS. This problem affects almost all the Windows versions of maps on this site (the Mac versions are not affected however, as they use a different format).

So.... "thanks, Garmin".  >:(

There are several GPS apps for both Android and iOS where the map data is stored on your phone, so they will work without any data connection or cell service. If you want live traffic information, you'd need a data connection for that, but it would use very little data. TomTom and HERE are two of the most popular apps.

https://www.tomtom.com/en_us/drive/gps-navigation/go-mobile/
https://play.google.com/store/apps/details?id=com.here.app.maps&hl=en_US

I don't think these will work on your car screen however, unless it's something new. AFAIK, Android requires you to use Google Maps or Waze.

Garmin has discontinued their StreetPilot app, I think they are worried that it took away from sales of their dedicated GPS devices. But it wasn't compatible with your car screen anyway.

I'm sure that built-in navigation systems are big profit centers for automakers, so they are not going to be very motivated to offer alternatives that let you use other software on their screens.

Doubt that you'll find the answer here, these forums are for the support of the free maps at GPSFiledepot. Not sure where else to ask, 5 or 10 years ago there would have been lots of places, but today the same sites are mostly ghost towns. LaptopGPSWorld is the only site I can think of, but I wouldn't hold out too much hope...

General Discussion / Re: Create LIDAR overlay
« on: October 19, 2019, 02:50:27 AM »
Note this is NOT the resolution I used for the map I posted above where my measurements indicated about 1 pixel per meter.

FWIW, resolution is usually expressed as [units] per pixel - such as "meters per pixel" and not "pixels per meter".  :)

In case you don't already know, here's how to find 1-meter LIDAR. Go to the National Map download page

https://viewer.nationalmap.gov/basic/

Drag/zoom the map to the location that interests you
Choose "Elevation Products" (NOT elevation source)
Check the box next to 1-meter DEM
Click Find Products
If any 1-meter LIDAR is available for the area you're viewing, it will be listed

Why were you not able to transfer it? Connect the GPS to your computer and open the Garmin folder. If necessary, create a folder named CustomMaps. Copy the Google Earth .kmz file to that folder.

You must use .jpg images for the .kmz, it will not work with .png images. Make sure that the image you created is no larger than 1024 x 1024 pixels. Also, only use letters and numbers in the filename. There's an old bug where a file named my_map.kmz would not work but mymap.kmz does work. This may have been fixed though, not sure.

I assume you already know where to find the LIDAR imagery, since you're already using it? If it has 1-meter resolution, then each map tile can be about 1km x 1km (1024m x 1024m). You can use 100 of these tiles at the same time.

For more versatility, you would download the actual DEM files from the USGS, then use some software to render them in whatever style you like. Sounds like MojaveMan has some ideas for this. I use GlobalMapper, which makes all of this trivial, and it can directly create the Garmin custom maps. It is expensive software however.

Again, look at the other thread i linked to: https://forums.gpsfiledepot.com/index.php?topic=4556.0

As discussed there, qGIS and mapc2mapc are useful tools for this. qGIS is free, open source software Mapc2mapc is not free however. g-raster is also mentioned in that thread, and is another tool that is worth a look. Again, it is not free.
