+1. Point Clouds
+2. Digital Surface Models
+3. Textured Digital Surface Models
+4. Orthorectified Imagery
+5. Classified Point Clouds
+6. Digital Elevation Models
+7. etc.
+
+Sadly, it does not do all of this yet. So far, it does step 1: Point Clouds. But outputs 2-4 are on their way shortly, so stay tuned.
