Scale tracks easily

Download an app that let's you measure distance on a map, I don't think google let's you anymore, at least on phones and tablets. Measure a straight area that is 600m or .19m depending on what unit you use and screen capture that. Use this picture for your reference, set your straight where you marked the distance and go from there and you should have a properly scaled track.

600 meters are .37 miles. That .19 mile figure is most likely the track length, which is being measured from half the straight.

Personally, I use a ruler and an Excel file that converts millimeters on screen to kilometers on the map.

You're right, I didn't even think to do that simple bit of math in my head. It's not that big of a deal, just use metric measurements then. The option is thee for everyone to use.
 
I am having a huge problem with scale. I have an image of a track I want to do, I know how long the real life track is, but I don't know how to scale it properly once I import the photo?

Until PD provides a scale tool that we can use after we started, I found the easiest way for me is to go to Google Earth on my PC, bring up the track map, use the ruler tool and measure the out to out of the track, then when bringing in the reference image compare that measurement to the grid and compensate for the home straight which is unfortunately bigger than a air craft carrier, if I have to.

The app has a scale, but when I attempted to place the image close enough to match the scale it didn't match. I needed 2000m, but it was a bit over 6000m. Too bad we couldn't just trace a track then type in how long it is at the end before we transfer it.

I put 200m reference squares and a 1000 m. Reference line or square beside the track image. Match those with the grid on the course maker app and you can get within 1 metre on the final product.

That is a pretty good way of solving this problem, but also a lot of extra work to the user.
 
With the original GT circuits I find a good image of the track, bring that image into Autocad and create a polyline tracing the shape through the center, then scale it up to it's proper scale, using the 600 meter pit area as a reference, I draw a vertical bar to the side at the length, then when importing into the creator align and scale that bar over the bar that represents to pit area. While in this process I can see if the pit section or other track areas conflicts are going to occur then make adjustments.

With real world tracks I'm usually using kml/gpx files instead of images.

How do you get the gpx data from a real track? I assume you don't physically drive them all in real life lol
 
I need to know how to do that create path thingy on google earth. Maybe my phones app isnt up to date. Thatd help a lot.
