After a few months of trial and error, I finally figure out the basic of aerial mapping. Blessed with good weather two days ago, I took out my Skywalker 1900, APM 2 equip with Canon S100 to a near by oil palm estate own by a friend. The Skywalker with my current param track extremely well even in strong cross wind condition.
The total flight time is about 30 minutes from take off to landing covering 320 Ha of land at 300 meter altitude. The cross line distance is 140 M and the camera CHDK set to release shuttle every three seconds.
One interested things I discover is the GPS location shown in the mission planner is about 160 m away from the google map.
From the total of 500 plus images taken, I trim down to 89 image and put it through Autopanogiga. ( mine is trial version so water marks appear ) and the result is quite promising. I'm new to this program so the image is all run by the program default settingwithout manual intervention. It may able to provide better result if I gain more knowledge with it.
My Skywalker is build base on much of the information @ http://conservationdrones.org/
