Having the mapping data installed on your GPS device is both a limitation and also a blessing, depending on your point of view, because you need to have the GPS connected via USB to your laptop in order to use those maps with Basecamp. As many maps as you can stuff onto your SD card Using the maps with Basecamp OPEN MAP FOR GARMIN SERIESBoth the 64 and 66 GPSMap series seem to accept this happily, though your mileage may vary with older models. This lets you keep the file names on the device unique and still carry as much coverage as your SD card allows. Instead of sticking with the original gmapsupp.img moniker I now use a format of gmapsupp_type_country.img where type is the type of map I’ve chosen, usually OSM, and country is the region contained, e.g. Well, it turns out you can, just be creative with the names that you give them. If only you could have several files called gmapsupp.img on your device at the same time! This was a lengthy process since each time my selection would have to be built in the background by the server, resulting in a bit of a wait for the email message telling me that my custom order was ready for download. OPEN MAP FOR GARMIN INSTALLThe other download options will let you install maps to your computer and then selectively copy them to your GPS, but that’s unnecessarily complicated and involves Map Manager, another Garmin utility which will probably be discontinued at some point.īefore I realised that you can have multiple regions on a single SD card I often performed a manual selection of OSM tiles to match whatever I was planning, instead of downloading the pre-built countries. OPEN MAP FOR GARMIN ZIP FILEChoose the osm_generic_gmapsupp.zip download option to be given a single ZIP file containing gmapsupp.img, which is the OSM map for your given region and can be dropped straight onto your Garmin device.If you haven’t added any additional tiles then click on the Download map now! link to the taken to a new page with several download options.Don’t do this now, there’s a better way to get what you need. If you’re OK with this selection then chances are you can download the data straight away, but if you want to tweak the selection by adding more tiles then you can do so after ticking the check-box above the map. Optional: A little way down the page, a map made up of many tiles will show you (geo)graphically what you’ve chosen.For example, if you need France then click on the Europe box and scroll down to France. Pick a country to download using one of the six drop-down boxes.I mostly stick with Generic Routable (new style) for most applications From the radio buttons at the top, choose the type of file you want.There are other installation options too, but the simplest approach is to download an image that your GPS can use, and copy that straight to the GPS. Getting hold of Garmin compatible OSM data couldn’t be simpler, just choose the region you want, download the file, move it to your device. Fortunately, somebody had the bright idea of placing such a tool on a server, and periodically compiling whole countries worth of OSM data into Garmin compatible map files. These tools were often command-line only and required some skill to use (looking at you, mkgmap) which kept them out of the hands of many people. Until OpenStreetMap came along.īuilt on the Wiki principle, OpenStreetMap “is a map of the world, created by people like you and free to use under an open licence” and it wasn’t long before people developed tools for embedding OSM data into their own applications and devices. But all of these had one thing in common: they were online and couldn’t be used on other platforms. OPEN MAP FOR GARMIN OFFLINEEach had a different take on what mapping should mean Google were among the first to offer satellite overlays, Memorymap sold a companion app for offline use, Bing gave us isometric “bird’s eye” views – the first pseudo-3d experience. We saw a plethora of different providers cropping up, from Google Maps to Memorymap, Streetmap, Bing, and our own venerable Ordnance Survey. OpenStreetMap in Basecampįast-forward a couple of years and online maps gained popularity as browser technology evolved, allowing seamless panning and zooming of downloaded tiles. Periodic upgrades were typically paid for as well, making ownership of useful digital maps an expensive business. OPEN MAP FOR GARMIN PORTABLEBack in the not-too-distant past, your only option for getting any kind of offline map onto your portable GPS device was to purchase one from the manufacturer, which would then be unlocked for use on that device and nowhere else.
