Club Motorsports 2023 v0.5

Club Motorsports is a private road course for cars and motorbikes located near Tamworth, New Hampshire. It features around 250 feet of elevation change over its 2.5 mile (4.023 km), 15-turn car circuit, as well as an 8-turn karting layout. Excavation of land for the main circuit began around 2010, with paving beginning in 2016. The circuit hosts track days, kart races, and other motorsports events. The owners of the track plan to build out the facilities to include climate-controlled garages and trackside condos.

This model was developed with the assistance of computer-aided photogrammetry. The latest publicly available aerial LiDAR (elevation) data is from 2015, before the track was paved and when there were piles of gravel or dirt obscuring the track surface. The client and I worked together over many days and hours of flight time in Fall of 2023 to capture over 3,000 high-quality, consistent-lighting drone photos, which I then processed through photogrammetry software (RealityCapture) and post-processed in point cloud cleanup and analysis software (CloudCompare) to form an accurate, high-resolution road surface mesh, which I then used to model the track. We encountered and overcame a number of challenges during this process, including accuracy enhancement of the photogrammetry mesh through use of GCPs (ground control points), with their elevations and lat/long based off of the uncovered areas of the public 2015 scan.

The model is still in development, and I am aware of a few missing components. In the download I have provided a file (Buglist.txt) detailing the bugs and missing features in this and previous versions. This list includes the following items that are missing from this model as of v0.4:

• The terrain's map texture is white, which means there isn't any variation in the detail textures
• No buildings or some other objects

All of these features are planned to be released in future updates.

@YelFerrari for commissioning the track model and providing literally thousands of photos of the track for reference;
@Leonardo Ratafiá for donating two camera sets he created for this track;
The USGS for making available high-quality aerial-captured LiDAR data;
All other contributions, monetary or otherwise, to this project.


If you'd like to help out with development in terms of monetary contributions, I've provided my PayPal link at the top of the page. All donations sent to that link that have a description relating primarily to this track (e.g. "for Club Motorsports") will reduce the price for the client to get the next version released.

If you can't afford or are otherwise unable to donate, but would still like to help out, the best thing you can do is to post constructive feedback on the model in the Discussion tab of this post.
