Bandwagon's Drones Thread

I HATE hate HATE curblines for topo....
ie i suck at them, and have sucked at them for ages.

i had a job where the city REQUIRED contour lines....the-small(5400 sq.ft.) site went from elevation 15.6 to 16.1.... i had contours @16.0 and 15.75.......stupid.

i also had a job where the city asked what sort of climate change mitigation was going to be taken from the site due to rising sea levels which they claim the site would be in ...in 2070...so the clients lawyer asked me...
i did the calculation for the site (city of cambridge ma base to navd88) to get what the elevation was so i could look at the FEMA flood plain elevation maps
i responded...none and gave this rational

those sea level rise charts the city uses are worthless and woefully overinflated as to what the sea level rise is actually going to do.
they say 2070 it will be in the flood plain... have them do the actual math When you see/talk to them again...
the site is 6.16' above the flood plain.
6.16'(6'2" basically)difference in elevation = 1877.568mm
2070-2018=52 years... 1877.568mm/52 =36.1 mm sea level rise PER YEAR or 12.8x the current rate of the actual data.

using noaa's sea level rise trend chart for boston harbor( https://tidesandcurrents.noaa.gov/sltrends/sltrends_station.shtml?id=8443970 ) the current long term rate of sea level for boston harbor is 2.82mm plus or minus 0.16 mm per year (basically 1/16 of an inch per year) or 0.93' per CENTURY (11 3/8 inches basically)
the current trend projected out puts 18 tufts in the flood zone- provided it maintains the SAME rate of sea level rise..
1877.568/2.82= 665.8 years until That address is in the flood zone.

Looks good. Carlson is releasing a photogrammetric series of drone software I saw.

Rofl. I said I saw they were doing it. Didn't say I'd buy it. Of course we use a 12yr old version of cad for all our work.

Which reminds me I have to reactivate it, the latest update to Windows 10 fucked up the activation and it reset.

I like pix4d.

OOOH that is sweeet.

Better the drone etc etc.


At a min I'd say dji phantom 3 or parrot bebop 2 they run 3-500 depending the parrot is the less expensive.

nice nice,

oh, that windows 10 patch that fubar'd up my cad activation, fubar'd my pix4d too.

any project would load fine, but trying to go into any mode besides the initial map view would crash pix4d. i had a job where i manually wrote down all the elevation differences, gave it to the boss to tell the client (quick and dirty flyover- just needed the difference in grade from a bypass road to the building 20' away (and 12-16 feet higher))..and he lost the page, i go, no prob i'll turn the program on and write it all down again...crash, crash, say hmm maybe corrupt project, re-run project- stage 1 runs fine, stage 2 runs fine, the second stage 2 finished and it switchss to 3d view,,crash (tried 3 time). i ended up deleting and reinstalling pix4d and that fixed the problem, original project loads and worked fine.

bypass road- centerline 4.8 gutter@breakdown lane 4.6 jersey barrier base 4.8 top 7.3 1st terrace 11.1 2nd terrace 15.51 terrace @building mid 16.9 @garage 18.6 @ building corner 20.7 @ driveway 20.9 (all elevations city of boston base- navd88 is 6.46' lower)

using that polyline thing if this was on the cloud, i could have had the profile in 10 seconds....

we grabbed an apple mini 4 for pix4d. not that we can use it atm, due to it being leaves fucking everwhere blocking the view except if we are in the city.

for surveying, we just got a new sokkia total station(we had an absolute klutz working for us a few years ago and he broke a sokkia set 6 total stations twice in the span of a month-doing the exact same thing, forgetting to screw the total station onto the legs(which is pretty much step one once you set the legs up over the point). needless to say he got canned (and he was the bosses grandson-my nephew)...boss(my father) is hesitant to going/adding gps due to fucking nothing being tied TO the state plane coordinate system in our area- we'd have to use it them take the shots and rotate everything to the property bearing system-doable-(most everything we do is assumed coords to start)--i give it another 5 years, provided my son actually does go to college for civil/geomatics he'll end up being in charge of that.

bloody pix4d is having a workshop 20 miles from my work in boston next tuesday and wed...and the Boss is on vacation-and i just got notification of it today...give a bit of notice beforehand people.,.... it also requires you to bring a laptop with the latest pix4d....but we only use freaking DESKTOPS at work.

and i am scheduled for like 8 projects i have start and get done next week, due to said boss being on vacation.
