Hi Subscribers,
I am making time series coastal erosion maps of northern coast of
Fukuoka prefecture, Japan.
I have got many aerial photos taken in 1947, 1961, 1966, 1975, 1982,
1990 and 1995.
I scanned them all with hi DPI and registered them as raster maps.
But they are distorted and cannot be overlaid with high accuracy.
I have to calculate anual erosion rates after tide level adjustment.
Does anyone know any good and inexpensive ORTHO tools for that purpose?
It is not necessary to be super accurate.
Thanks in advance,
Hiko
