I have Garmin's AUS & NZ Topo lite v5 for my GPS. Here is some Topo comparisons which I got from another site which look very close to what it's like on my GPS.
It's really good because I don't need street routing and the smaller size means that the Etrex does quicker screen refreshes and shorter search times. But it has everything else as expected of Garmin Topo - I also have 'Contours Australia @ 5m' DVD when it was given out for free years ago.
These neatly overlay the Topo map and work well in further enhancing the 3d effect when topo shading begins to fade out on maximum screen zooms. If you use the Garmin co-ords for the summit, then yes. I usually am not at the true summit when at the Garmin-summit. On the other hand, OSM summits are pretty darn good.
I will generally be on the true summit, or at least very close to, when I'm on the mapped summit point. Did you see if the same error occurrs with the new map? I'll attach an averaged waypoint at the end, if that helps. The 50-500m margin of error seems a bit large to me. I've walked along the same track separate days and they are all roughly on top of each other. This is from three days, five tracks, and over a week separation.
I have a variance of around 10m, which fits in with the link you sent me: 10m variation in my track would equal a margin of error of 5m, of course, it's a small sample size so the margin of error could be twice that. Even doubled, it's still an order of magnitude less than 100m. Of course, in canyons and forests quality decreases, but clear mountain summits and ridgelines should not have that problem. I don't think that guy included GLONASS in his calcs, which should theoretically improve accuracy even more. I have also tried waypoint averaging. This example was for ten minutes while I had a quick lunch break. I was in the true saddle, the lowest point between the two knolls on the ridgeline.
300m error this time. Zone-5 wrote: Also the 10m accuracy is a myth, try 50m and it's a radius measure so in reality it's 100m margin of error. Unless you wait the five to ten minutes to average each way-point, don't believe the accuracy hype from the manufacturers! I don't know if that is exactly right, from what I have read most GPSr are a lot more accurate than 100m. I couldn't find the section in that website you shared that discussed accuracy but from what I can gather it works something like this. '.What does it mean if the receiver states an accuracy of 4 m?
This readout refers to the so-called 50% CEP (Circular Error Probable). This means that 50% of all measurements are within a radius of 4 m. On the other hand, 50% of all measured positions are outside of this radius. Furthermore, 95% of all measured positions are within a circle of twice this radius and 98.9% of all positions are within a circle of 2.55 the radius. In the given example, nearly all positions are within circle with a radius of 10 m.

The determined position is in the worst case accurate to 10 m' If you're interested in calculating the accuracy of your own unit to both CEP (50%) and 2DRMS (95%) this is a good. My own observations on the accuracy of my GPS correlate pretty closely to the numbers in that tutorial, maybe dropping to 15m in a worst case scenario (but most of the time sitting between 3 and 10m). Most of the modern units also get an accurate fix a lot quicker than 5-10 minutes too, even if performing a cold start.
I don't know about your etrex H as it is an older model but my etrex 30 only takes a minute or maybe 3 or so minutes from a cold start.

Yes, it is old, and no longer updated, and basic info, but you can test out some topo maps on your GPS. The other thing you can do is make some custom raster maps but you have to calibrate them yourself, and it can be time consuming. In VIC there are good maps from the NRE has great maps that you can download, but you have to calibrate them yourself.
Both the eTrex 20 & 30 can do these custom maps. There are free tools out there to both calibrate the maps and break the images up in to tiles that the device can handle properly.

I can't find any info on Garmin's site about the V5 'full' maps. Lite: Full: Lite has 40m contours, full has 10m contours. I'd already checked Garmin's site and came up with the same page as your link to the 'full' one above. The thing is though that the 'full' one has the same Garmin Part Number as my V4 topo so that's why I thought it was still only the V4 available.
I'll shoot Garmin an email. Phyllocladus aspleniifolius Posts: 570 Joined: Tue 28 Oct, 2014 5:31 pm Region: Other Country Gender: Male. Watertank wrote:Does the Topo Lite V5 work with Basecamp - that is can I see the maps on my computer? It isn't clear for me from the Garmin website.
It says 'The download is installed directly to a device or microSD/SD card and is not accessible on the computer.' It is a bit unclear, but you can view it using basecamp, if your device/microSD card is connected by USB and recognised by the PC. What they mean is that it cannot be installed directly to basecamp like the DVD version. Once you have it downloaded and installed on the device/microSD if you have problems, try using JaVaWa Device Manager to see what is going on. Remember to close down JaVaWa before trying to open the map in Basecamp.
