Garmin 500 - Google/Bing Maps Incorrect Plots???

Former Member over 11 years ago

Hi

When I look at the plot of my rides using any of the map software in Garmin Connect the plots are always a few hundred metres from the routes I took so never shows on the actual roads I traveled. The satellite option is spot on but the maps are not, is this something I have to live with or is there a solution???

Using a Garmin 500 and based in china currently.

Cheers

Might be just how accurate the maps are for your area. The maps for Garmin Connect are provided by Google, Bing and OpenStreetMap. At least that's the case for me here in the USA. Do you see the same issue with each one? (There's a dropdown to select which map provider you want).

I think its due to the Chinese government - they require that any maps are offset, to make them inaccurate.
Plenty of websites reporting this, eg http://home.wangjianshuo.com/archives/20081109_all_maps_in_china_are_transformed.htm

Have you tried OpenStreetMap? I don't think it is affected by Chinese laws.

Have same issue with Bing & Google maps but OpenStreetMap does not load so had assumed they did not have China covered?? Will try again.

Thanks for replies...

I don't doubt what Craig_Wallace said. Russia back during cold war times was so concerned about 'security' that they published inaccurate road maps just to confuse potential invaders.

OpenStreetMap does cover China. The OpenStreetMap option in Garmin Connect uses Mapquest Open, it looks like it is pretty good for China, at least for the cities. eg Beijing: http://mapq.st/17n9Xtt

Maybe it is somehow blocked by your internet connection, eg a firewall. Does this website work for you: http://open.mapquest.com/
