Re: [CentOS] USB GPS
Anyone ever used the iGPS-500 under CentOS 5? Any recommendations on a USB-based GPS that just works? I use the Garmin GPSMAP 60CSx on CentOS. This is a very good device (but more for offroad activities). When you connect the USB cable it is identified as a /dev/ttyUSB0 device that you can use with GPSBabel. You need to give the proper permissions for your user on this device (I had an udev rule for Fedora, but on CentOS I did not yet too time to set it up again). From the GPS unit itself you can activate an 'USB mass storage' mode which will make the internal SD card appear as an USB mass storage (like an USB stick). This is very handy if you want to retrieve automatically generated track files in GPX format or update the maps (although I recommend using a card reader for that: much much faster). A bit OT but still making sense in this answer: you may be interested by the excellent community developed maps of OpenStreetMap (http://www.openstreetmap.org/ , licenses and production mechanisms similar to Wikipedia), which can be downloaded in Garmin format: http://wiki.openstreetmap.org/wiki/OSM_Map_On_Garmin/Download (or the Garmin maps can be generated using http://wiki.openstreetmap.org/index.php/Mkgmap) Most of the above probably applies to all other recent Garmin devices but you should double check. You can also have a look at the GPS review from OpenStreetMap users here: http://wiki.openstreetmap.org/wiki/GPS_Reviews (but you won't find much information on supported OSes, esp. CentOS) ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I use my GPS to collect data on reptiles and amphibians, dump the data to gpx, pass it through http://www.gpsvisualizer.com/elevation to fix the elevation (which can sometimes be considerably off in the unit, especially with tree cover), and provide georeference data when I submit the data to the nafha database. I don't do any mapping with the computer, unless you count finding spots that look interesting in google earth and uploading them to the unit for me to then find out in the field. Lot of people just like me, too. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I do not have personal experience but I hear the Garmin models work
well. I have a serial port Garmin model that works well with gpsbabel,
and I believe the setup for USB is similar.
http://www.gpsbabel.org/os/Linux_Hotplug.html
has instructions for fedora - I'm guessing the fc{5,6,7,8} instructions
are what would work in CentOS.
