Narrative:

I was on final approach to runway 28. I thought I had clearance to land. I had reported 'on final' as instructed. At about 1/2 mi from the threshold I noticed a low wing single engine aircraft departing runway 10. I estimate he passed overhead by 500 ft. After touchdown I saw that there was a small twin engine aircraft 'on the numbers' of runway 10. This aircraft exited the runway. I contacted ground control after clearing the runway and they instructed me to contact the tower by phone. When I called the tower they told me that I did not have a clearance to land and that they would contact me again after talking with the other pilots. As of this time (pm:00 local) they have not contacted me.
