From blimp to page
An afternoon with the newest tool in the Pyla-Koutsopetria Archaeological Project arsenal, PKAP Airship One, produced a series of spectacular aerial photographs (the adventure of the airship was documented by Dallas Deforest here).
I did some quick, post-processing of the low-altitude aerial photographs, which I document below. My main interest was transforming the aerial photographs into quick plan views. I first georeferenced the image (and orthorectified them to compensate for any distortion) using a series of points acquired by GPS.
I then sketched in the most visible features in the photograph in ArcGIS. The final image is a drawing, base on the photo, prepared for ground-truthing this afternoon in the field.
