General / mapping pine plantation problems
« on: November 18, 2015, 11:28:08 AM »
i am trying to map fully grown pine plantaions post fire  but cannot get the middle photos to align (my AOI) , i have mapped newly planted  pine(1m) and  bluegum (2-3m) plantations before with success. (infact the new plantings surrounding my AOI come out great)
camera - sx260 (NIR modified)
height 120m
photo every 2 secs (~ 80% forward overlap)
60% side overlap
NO GCP
align medium / reference, / default tie points
did two seperate flights to ensure overlap (one North- sth other SW-NE)
made a chunk of best overlap area with > 2000 photos in ~ 30ha,  processed seperately  still no sucess
i can go through the photos and clearly see overlaping features
Has anyone successfully mapped a fully grown pine plantations (20 - 30m trees) ?
if so what altitude  did you use?
( as a side question is there a way to open two photos side by side to manually add tie points?)

All my outputs are upside down / mirrored, i am using the GPS dat from the photos and the results are inside a dish.
all of the coords are correct as i can check the location in Arcmap.
what am i doing wrong?
