I'll be running a couple of GIS modules as part of our undergraduate and postgraduate degree teaching here at the University of Gloucestershire. I'd be really interested to hear about any experiences/ideas people have with integrating KAP into geography/GIS teaching. I think it would be fun to do, but I'm still not entirely sure what we'd do with the oblique low-altitude aerial photos that we capture. How does one begin creating a map using KAP images? I'm used to dealing with orthorectified photos and satellite images!
The tracking lines join data points recorded at set time intervals.
The GPS units integrated into some cameras will not work in continuous shooting mode (and often interval mode) as they record only the position corresponding to the first image. External triggering of the camera (GentLed etc) will overcome this problem.
generally you need some form of control points on the ground that require co-ords of some form to tie into the images. These are usually crosses on laminated white paper that are attached to the ground. Another method can be employ the a gps unit or built into a camera itself, the images will have exif information with gps co-ords that can be roughly tied into a flight path that can be matched onto features on the ground. this is a little rough and ready and not accurate enough for gis methods. A further method is ortho-rectification using software such as Airphoto which could be exported into other packages for refining. If the image was truly vertical, then the image could easily be pulled into GIS (QGIS) and rectified using simple control points onto known features. I usually use CAD and overlay this onto a map tile in GIS and then pop the image using controls over the CAD image.
