Hello, Its been 3 weeks since I bought the Wookong and I can't express how disappointed I am at how they announce the ability of doing Orthographic mapping. The simple reality is that due to the fact that GPSexporter puts out coordinates of where every picture was taken using the Photo-geometry tool but does NOT put a time value next to them. This makes every single geo-tagging software useless. Also the fact it puts the information in plaintext is a pain because a separate program needed to turn that into a usable file such as .GPX inorder to process the coordinates. After all this you are left with a .GPX trackfile that has no time associated with each coordinate. No program can sequentially geotag pictures and from this point on it needs to be done manually. The second issue is that the Servo-Action configuration sends a pulse to take a picture and it lasts over a second, if you are doing high resolution mapping where it takes pictures every 2 seconds it can make any commercial shutter cable stutter and skip taking a picture, meaning your entire data-set is shifted and you need to manually locate where this hole was made.
I came to the conclusion if you want to use Wookong to do aerial mapping you need a completely independent geo-tagging solution and simply have Wookong drive your multirotor while your camera/geo-tagging system does the rest. I bought wookong only for this feature and I am using a NEX7 with an IR shutter. Nex7 doesn't have a Geo-tagging solution so now I spend $1200 camera+$1300 Wookong that doesn't do an advertised feature.
If anyone has gotten this to work, it hasn't been simple, They would have needed to write their own geo-tagging software that is compatible specifically with the mediocre data the wookong puts out, and paying $1300 to do this seems ridiculous. So please avoid wookong if you want to do Aerial Mapping.
Also I read is pretty much impossible to send an E-mail to DJI, but they could fix this with a simple update to Ground Station and GPS exporter, If they could simple have gps-exporter output the time when a picture was taken, and have groundstation allow a servo action of half a second all my headaches would be gone. GPX format is VERY simple and I am sure they could fix this in a simple update, although I'm not getting my hopes up.
