Import to BTB from Google Earth

Discussion in 'Bob's Track Builder' started by Brian Johnson, Jan 28, 2015.

  1. Are there any tutorials on how to import data into BTB for the road and terrain from Google Earth? I am on the current version of BTB, but I am very new to any of the point cloud stuff and don't really know what to do.

  4. There are some tutorials for importing a KML file somewhere here in the forum. Short answer is that you generate a KMZ file for the track in Google Earth, use http://www.nearby.org.uk/elevation-kml.php to fill in the altitudes & convert to KML, and import. Don't use too many points when drawing the KML. Fine-tune the import over a background image by adjusting nodes.

    For using point-cloud data, see http://www.racedepartment.com/threads/working-with-aerial-lidar.96590/ and a database of tracks covered by aerial lidar is described in http://www.racedepartment.com/threads/emerys-public-lidar-database.97718/

    These will have to do until Brendon releases his recently demonstrated direct import of Google Earth terrain.
