Neither google maps nor satellite map did fit gps coords when I was last time in China 2009. I wondered if that was on purpose. Haven't used Open Street map then, perhaps that's an option today.
@Criggie i did that last time.
I've downloaded as much as fit on my external drive. Before I flew I had an allnighter trying to get a server working, running some hackish/botched set of scripts to mimick wikimedia cms accessing the content.
It was a seriously bad idea. Went to bed less than an hour before I had to get up to get to the airport, then couldn't sleep on the plane. In China it all fell apart.
@Batman I've tried to get past the great firewall in an internet cafe in 2008. Used ssh to get onto my desktop at my German university. Used lynx and wget to get wikipedia and news. That worried the resident snitch of the cafe profoundly. He got quite agitated and texted a lot, with quite a lot of people coming and watching me.
