So, having signed up three days ago I took special care to note down the names of nearby streets as I passed them. I've corrected over 10 street names in my area, although there were several streets missing from OSM. I'm not sure my cheap GPS is sufficient to map them, as it is only accurate to 0.0001°, and when I tried to measure a short footpath it located one endpoint 14m from the nearest road. Is this GPS simply too inaccurate?
