Narrative:

A VFR flight from shelbyville, tn, to tupelo, ms, I entered a tower controled airspace without first making contact. During my planning stage I used a new to me internet service and downloaded my chart. I did not realize that it was in a WAC format. I have been used to using sectionals. I did not notice the tower at destination. To compound the mistake I used the frequencys in my VFR GPS to make my calls at the destination airport. The tower has been in place for 3 yrs and was not in my GPS database. The error was caused by improper flight planning on my part. I contacted the tower immediately upon landing. I have since thoroughly reviewed all phases of flight planning and chart reading and will never make this mistake again.
