Can you school me up on this? How did you download just Texas? Through one of the mirror sites listed on the OSM page? It looks like the entire OSM database is 32 gigs--more than I want to load on my PC or my GPS.
Select OSM maps
here guys.
You first
select the tiles on the map which is the coverage area you want to download. If you want the entire world and have large memory card go for it. I chose US, Canada and part of northern Mexico. Since the file is so large, you will be placed in a waiting list or "que" until the server has created your IMG or image file. How do you know when your custom map request is ready?
OSM will
send you an email that will tell you that your map has been built according to the squares you selected, and will provide you with 5 links. There are
only two likely to be on interest to you, one will be the map itself, and one will be if you use MapSource. If you use BaseCamp or don't need the map on your computer, then all you need to download is the map itself.
The map for your Garmin sat nav will be the link containing the IMG format file, which will be zipped. Download it. Note where you are downloading it to so you can find it once it is downloaded.
The link for the software file for the MapSource are also clearly labelled in the email. The link is valid for I believe a little over 40 hours, so don't delay in downloading the file!
Make sure and prepare a SD or micro SD card for your map ... you will load the map onto the memory card, and then insert the memory card in to your sat nav. Firstly on the blank memory card create a directory (folder) and name it "
Garmin". Second unzip the file directly into that Garmin directory. The card is then good to go ... place it in your sat nav and select the map to use it.
For those dudes using still using MapSource - install the software for Mapsource by double clicking on it. The next time you open MapSource the OSM map set will be "selectable" on the drop down map selection box at the top of the page.
I hope this helps. OSM is truly a wonderful Open-Source tool for traveling....on a motorcycle which is our case. You can
totally replace all Garmin map updates if you decide to go the OSM route. Quite a few Advrider globe trotters use the OSM approach with much success. You can also annotate the maps if you encounter any strange mapping anomalies for others to benefit from in future map updates.
