Quite impressed with the detail on the mapping I got from them, plotting routes and putting in waypoints using basecamp is good. Should all be good to go when I get home and get my Montana
I just used the Generic Routable, has any one used the Generic Routable (new style) and is it much better

Looking around at my broad interest in "where maps originate" I came across this method of downloading OSM:
Free maps for Garmin from OpenStreetMap
While it is fundamentally based on OSM it also incorporates topographical data from other sources, as described in the website.

Not all of the currently available OSM is in this site, because it seems to be based on a version of crowd-funding to get a map installed into the site:
Free maps for Garmin from OpenStreetMap - More maps

I suppose it doesn't cost a lot and the website owner is doing some of the computer based work that is otherwise necessary.

Just like the buses in the UK, it seems that this type of software arrives in pairs.
Here's another website that provides an alternative access to OSM maps and these are also complete with overlaid contours, as an option.
Home (talkytoaster.homeip.net)

Based in the UK, the website owner naturally specialises in maps for the UK et al:
FREE British Isles and Ireland Maps Home (talkytoaster)
but offers to provide OSM maps for elsewhere in the world, at a price http://talkytoaster.info/payment-faq.htm

Maybe there is a market for providing OSM maps to those who don't want to do it for themselves?

I have downloaded BaseCamp on my Windows 10 PC and downloaded the OSM as per the initial post. This is in a folder on a microSD card in a 'Garmin' folder and works fine on both my GPS (an old eTrex) and my laptop.

Rather than quit when I was ahead (!) I have also downloaded MapSource since my old eTrex does not work with BaseCamp. (I followed guidance on Wikipedia which advised that, once BaseCamp is on the laptop, it is then possible to download MapSource, which as proved the be the case).

I have run the osm_generic_windows.exe file which has created a Garmin/maps/OSM Generic Routable folder with 67 items in it, 64 of which are numeric .img files (e.g. 63240931.img). The others are two small .mdx and .tdb files and an uninstall.exe application.

When I open MapSource it shows no map available. How do I get the map to show up?

Cheers

I posted this in another section and people recommended that I repost it here.

===============

I use a Garmin nuvi 2567lm GPS device and take it with me wherever I travel. It's a car GPS. But I also use it when riding a motorcycle. I place it in a handlebar mounted waterproof pouch. Garmin offers regular map updates which I install every now and then.

While preparing for my trip to Sri Lanka I couldn't find a Garmin provided map for the country. I searched online and found other companies selling Garmin compatible maps for Sri Lanka. I also came across a website called garmin.openstreetmap.nl which claimed to offer free maps for Garmin GPS devices. These maps are based off data provided by OpenStreetMap, a "community of mappers that contribute and maintain data about roads, trails, cafés, railway stations, and much more, all over the world."

I had heard of the OpenStreetMap project before, but didn't pay much attention to it because Garmin was providing the maps I needed. But left with little option, I decided to try out this web site and see if the maps were any good.

To get a map you need to choose the country on the web site and download it. I left the map type to the default (generic routable), picked Sri Lanka as the country and the map on the web page below highlighted sections that covered Sri Lanka.



I then clicked the download link and was asked to select the type of file.



I picked the windows executable as I use the Windows version of Basecamp software to manage my GPS. I ran the executable and installed the map on my computer. The anti-virus software on my computer complained, but I crossed my fingers and ignored the warning.

Next I plugged in my GPS to my computer, started Basecamp and proceeded to install the map on the memory card of the GPS . I went through the wizard and the file "OSM generic routable(LKA_20-01-2016).img" was copied onto the SD card in the Map folder.

I set this map as the current map in Basecamp and zoomed into Colombo city. All the major roads seemed to be there.



I zoomed in a little more and found that the map had a significant amount of detail in it. Pleased with myself, I proceeded to add way points for my ride around Sri Lanka and created a route.

After reaching Sri Lanka and renting a motorcycle, I strapped the GPS to the handlebar and was surprised to find the map blank. Surprisingly, the GPS was guiding me along roads asking me to turn left and right at intersections. It was as if the map was somewhere in the GPS but I couldn't see the roads. After some fiddling around I figured that multiple maps were active on the device and the OpenStreetMap was hiding under Garmin's map which didn't have any data for Sri Lanka.

I deactivated all maps except the Sri Lanka OpenStreetMap map and the roads showed up on the GPS. I spent two days following the route I had planned and the OpenStreetMap map worked like a charm. The map was completely routable just like Garmin's maps and I could safely take detours and have the GPS route me back on track without any problem.

garmin.openstreetmap.nl gets two thumbs up from me.

.exe means an executable file which means it is a "mini programme" of some kind (the sort of thing that anti-virus programs tell you to steer clear from and never download them or execute them!!)
In this case, OSM executable will load the downloaded maps into a computer that is running/compatible with MS windows - step by step is in the post above.

The original post of 2012 remains valid with relevant updates flagged up within this thread - certainly the technology does not stand still.

ps
I have added a note to my earlier post about guidance in using basecamp (and am about to add another, but this is starting to very much move away from the original purpose of this thread - as pointed out earlier).

Hi Dave, really appreciate your help here ok.

Ok, i have done all these stages as per your guy on last post but cant see any maps on basecamp. Are they supposed to go in to BC by themselves because they have a combined 'installer' programme ...????
