"Thanks Herman, we used to use a crop dusting bar in geophysics flying. When you are only 60m above the ground at 130kts its handy if the pilot is looking outside! I find young pilots like a screen to help guide them onto the line. I am going to give…"

"Thanks for the replies guys, I will try this out in the Cessna 172 in the next few weeks and let you know how it goes."

"Marcus, this would not help me as I may have to ferry 100 nm to a project site. If I am taking a photo every 70m that adds up to a shite load of photos, before I even start the survey. For manned survey you simply need the camera to trigger at…"

"Ok then it is going to be a no for me as I wanted to do it the old fashioned way and have pre-planned trigger points. As the pixhawk would have no servos connected could I run it in auto and still fly the aircraft manually, and have it trigger the…"

"Andre I did not want to use the trigger by distance function. I wanted to create a survey grid, and then fly the grid manually using mission planner for navigation assistance as you mention. So I think you have answered the question but if I fly a…"

"Yes Agisoft does generate a mosaic but again the problem for us is that it is a mostly automated process and the operator has no control over cut line placement. We had a script written which allows each frame to be exported as an individual ortho…"

"Yes we did look at the mavinci but we found $70k Australian a bit hard to justify. It looks like Eagle bait to me and I doubt mavinci will be happy to hand over another one if it gets nailed by an eagle on its first flight? Also most mine areas in…"

"We evaluated both about a year ago for processing data out of our manned aircraft. We found Agisoft to be the better package for us as it allows more user interaction in the triangulation process and DEM/DSM editing. The version of Pix4D we trailed…"

"Yes unfortunately a number of people here in Australia have already found this out. Certain UAV manufactures have been promising the world over here but not delivering. We are getting a steady trickle of work with our manned aircraft from clients…"

"Our client is after high accuracy mapping for an initial site survey for mining operations and requires accurate photo centres and a metric camera. Normally we would use our manned survey aircraft (C172) with a 39 or 80 mpxl camera and DGPS photo…"

"This could be an option for us but timing is tight we may be interested in a pre-production aircraft. How is it launched ?
Cheers
Erron"

"It looks like a good UAV and if I could squirrel a bigger camera (24mpxl) in there is may be suitable. The project I have to fly is around 450 line kilometres with a 24 mpxl camera so every megapixel counts. 
I was thinking a bigger air frame which…"
