I was involved with the development of the very first version of RoadTracker from GeoEye for FeatureAnalyst (I provided the GeoEye engineers assistance in developing their plugin for FeatureAnalyst).
This month – they released version 2.0 of their awesome plugin. I am sure they have added some great new features – unfortunately I dont have a license to ArcGIS to be able to take it for a spin.
According to the press-release:
The upgraded application, functional on any road surface type using either panchromatic or multi-spectral imagery, accelerates the collection of roads and other linear features from satellite or aerial imagery by up to a factor of four. This tool also includes automatic feature attribution and other smart editing capabilities that greatly improve speed, accuracy and workflow when collecting map-quality linear features.
Here is a video I created using the first version of RoadTracker: www.youtube.com/watch?v=86TVj88BaLE
