sorry for double post
will try with higher c what happens
here are two screenshots one with two pictures and the other with their location
the trees in edges are all "leaning" is this from camera settings? (1/1000 , f/3.5,iso-250)

General / mapping pine plantation problems
« on: November 18, 2015, 11:28:34 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?)

thsi is what ia ma doing with some success
Proces the images out of camera in agisoft as per documentation
export a jpeg (with world file if you want to laod into a GIS program)
process exported jpeg to NDVI using Fiji/imageJ or a raster calualtion in ESRI / QGIS /Globalmapper
go to flightriot for info on fiji/imageJ (http://flightriot.com/imagej-fiji/)

it is only in the program, when i export to local utm coord system it is correct
thansk you camera calibration did remove "bowl" effect

General / Ouptus are mirrored
« on: August 18, 2015, 12:45:17 PM »
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?
i have atatched a screen shot showing the dish
