I have briefly looked at the adding a legend. As far as I could see in the google maps api V3 there isn't a standard element which would work as a key. it could probably be added relatively easily with a div overlaid on top of the google maps layer, but I am not sure if it is necessary. > > I am unsure about how it is best to use the colors.

I don't know of any standards either. Quickly doing a Google search seems to give a lot of examples which go from blue to red to white. Perhaps this would be easier to interpret. Looking at a gps trace from cycling through a town with my current system seemed slightly confusing to me. > > > I also added a feature where you can click on the path and it will pop > > up a box showing the speed at that point, this saves having a key. > > Great! What about showing pace as well? This can replace adding a legend. Adding pace would be straightforward. While looking through the API I found that you can set up the little info boxes so that only one appears at a time. I am unsure if this would be desirable behaviour or not. On the plus side it would save having to close a load of boxes if you look at the info at lots of different points. On the downside it prevents people from having multiple ones open at a time to compare, which could be more useful if more things like pace and heartrate are added. I favour keeping the current approach since it gives more control to the user. Also the current implementation assumes metric units which is not good since you can choose US units in the preferences which should be followed. What I am currently not certain about is what units the data from the activity.tracks distance field uses. If your gps is configured as metric then it gives the distance in km. If this is not the case do you know if this is still in km? > > > Currently there is no gui, you can switch between global and per workout > > at line 112/113 (it is set to per workout in the patch).
