Maptitude - http://research.umbc.edu/~roswell/maptitude.html
Dear Mike,
I was caught by the description of your work. I did some oblique photos of
shorelines long time ago in Ireland and I am about to embark in a similar work
this year in Argentina.
I would very much appreciate if you could provide more detail on the type of
hardware you are using (photo camera, GPS, etc) and the software you are using
for keeping photos and positional information linked during the flight.
Also, while going through the description of your work I have noticed that you
are using the standard maptitude interface. You could do some of those tasks
faster with a little programming with GIDSK. The map editing needed to locate
the photo on the coast is a simple macro and can work well for you
Cheers,
Armando Scalise
