Hi guys,
thought I'd share a survey that I did last week. Was a fun and slightly different and nice to get out of the city for a bit.
So details are that client (did the survey for another surveyor that has too much work actually), but it is a Big 5 Game Reserve 37 000 ha. They bought a new lodge on the adjacent land and want to extend the watering hole dam wall upwards by 2.5m. So they needed a detail survey of the rock wall from 1950s, the empty dam up to 2.5 above dam wall level and then 500m downstream of the dam. entire site is maybe 800m x 200m
Slight issue is that is an active reserve with Lion, Elephant, Rhino, Leopard and Buffalo so had to be aware of that, but it is in a beautiful reserve.
So surveyed the dam surface, wall etc by GPS from Trig (seen in photo) and then placed about 15 GCPs and did an aerial flight at about 110m getting 350 photos and processed using Pix4D. GCP was surveyed on RTK (I know and I don't care). Final comparison between GPS data and Point cloud was less than 0.050m on surveyed points.
Here are some photos and a pic of final ortho and contours.
Looks like a great result. What is the general elevation?
Our version of 06/07/17 was over a month ago.

Much the way the toliet drains backwards in the southern hemisphere, the calendar months in the year also run backwards.
You all have it wrong. The correct order for the calendar is the same as for the clock: largest to smallest. If I'm writing it I use 2017 Jul 6 with month spelled out to at least 3 letters and if I'm putting it in a file name it's 20170706.
Any animal encounters?
As usual, the way we do it in the US is all backwards. I use Bill's method for short dates and file naming since it provides natural sort pattern. While the day/month/year format is not as clean for sorting but it is the standard the other 7.1 billion inhabitants of the spinning rock.
P.s. Don't get me started on northing, easting or run over rise.

I use the US Military date. 06 Jul 2017. I spell out the month in files names, with the new data collectors having more space for file names is a plus.
Okay, I forgot about the military, but then that is a socialist metric organization as well. So make that 7.1 billion plus the ~2% of US population that has been through the whole DOD gig.
Hi Richard. Average elevation is about 1330m MSL.
Bill there were some animals in the vicinity while I worked. Some 80 or so Wildebeest, 2 packs of Warthogs, a very angry Ostrich, about 10 Zebras and 2 adults Giraffe with a baby giraffe. In the valley area we did find a carcass of a wildebeest, probably killed about less than 24 hours before we came by, and saw leopard and lions footprints in the mud surrounding the carcass. Most of the animals scattered when I started working. The ostrich, wildebeest and warthogs were the only ones that sticked around.
Here is a photo of one of the Zebra. Was a quick one zoomed on the phone so quality is bad
