Well you should ofcourse never soly rely on a gps, because batteries can get empty or the thing gets lost or whatever. Preparation and a 20 bucks standard highway map will help you get along quite nicely. This is what I do anyway because getting a general overview of an area from a 4" screen and slow processor is no sinecure.
Just browsing around New Zealand doesn’t give me a feel that coverage is very good, but I could be wrong as New Zealand is way less crowded then Western Europe. Your future contributions for NZ are very welcome ofcourse
hi Lambertus. Glad to have found such site discussing about garmin maps.
i have a garmin 255 and wanted to install the map of cyprus. have noticed in my unit that only the major roads are available.
how can i install openstreet maps on my unit?
This weeks update is delayed due to tool problems. I’m reconfiguring to work around it, then do a regular update followed soon (hopefully) with an update using the same data but with the transliterator results from greencaps included.
Edit: the new update is online. Looking at a sample in China it seems that using the name:zh_py tag is working very well! Next update will hopefully contain Russian, Polan, Romanian and maybe some other transliterations using greencaps’s tool as well.
Great Job guys. I am continuing to edit my area, and have covered a lot of territory for just myself working on it. Lambertus, I have a question. On your GPS unit, what is your accuracy reading when you are mapping. Mine is 9-14 fee always and was just wondering if this was sufficient.
sphyg: good job, have you become addicted already?
Under normal conditions, placed on my bicycle mount and clear sky view the GPS displays the inaccuracy as 4-6 m. It gets worse in dense built-up areas or heavy tree cover. Keep moving in straight lines as much as possible helps the algorithms to estimate where you are.
9-14m is sufficient enough, especially if you are in unmapped countryside areas. A line that is possibly 10m off is better then no line at all.
It has come to my attention that some map building requests don’t succeed (resulting in only an osm_routable_tiles.zip). This is probably due to an too-complex tile in the Netherlands (there might be other tiles too). I’ve reported this and hope a fix will be available soon.
I think sphyg had a typo (fee) and he, like me, resides in one of those less advanced parts of the planet where they still use “statute” units rather than metric. 9 to 14 feet is pretty good. Sphyg, are you using an external antenna? WAAS?
I am addicted. My wife is hating me for it. You misunderstood me. Mine is feet. 9-14 feet would be 3-4 meters, not 10. So I am assuming that I am getting a good enough reading for reliable maps. Our measurment are, I belive, 3 feet = 1 Meter
Yes, you’re right. I am using statute. I can switch it to metric to see what I am reading, and if its 4-6 meters then I know I am doing well! I just changed it as a matter of fact, and I am 7M accurate, INSIDE MY HOUSE! So I will change it back to ft as I know I am doing good enough! WAAS is enabled, but no external antenna. I do it mostly on my bike, so would an external help. May look into getting one if it improves accuracy a lot.
I’ve been using a 60CSX with and without an antenna. With an antenna and good observing conditions the EPE number improves (from 15 feet to 7 feet for example) and the signal strength bars are all at full height, but there doesn’t appear to be a significant improvement in tracklog accuracy. I generally don’ t use WAAS, because, the few times I did, I didn’t see any improvement in accuracy.
Two side by side comparisons between an Oregon 300 and the 60CSX in good observing conditions didn’t show any significant difference in accuracy. I’m looking forward to testing both under difficult observing conditions (canyons), but that won’t be for a few months. The 60CSX must be really susceptible to multipath error if signals are limited, because my canyon tracklogs without an antenna can be spot on when I have a good view of the sky, and off by a mile when I don’t.
thank you for your maps, they are really great!
Today i tried to download a new version of the maps. But the installer for roadtrip, mapsourse and the map for Garmin devices were missing. A second and a third request didn’t solve the problem.
