Surveying in the rain yesterday. I stored 3 points, over a period of 15 minutes, that were fully verified. They were all inside a 0.05' circle.
Surveying in the rain, is a part of this game. Storm blows in, and you have to get done.

Happy Friday to all!

Nate,
Is this like TDD setting up over 10 dimes in 15 seconds?? 3 points within the SAME 0.05' circle?
You have a good day too.

So it is. You seem to have survived it. And if your new cube got completely dried out before you did everything will be fine.
The keyboard went funny, when it got pelted with rain. Random input....
I will want some sort of visor on it, for rain work. I'm thinking about how...maybe a little elastic strap around the unit, with a little thing sticking out in front. Like a square bill, on a baseball cap.
IF I'd had a paper towel with me, or a mechanism to remove the copious amounts of water, it would have helped alot. My daughter came and ASKED me for my paper towel, so it was not with me.....(I have a habit of carrying one, due to the touch screen).
But, it did well in the woods. And rain.

Is that canopy in the photo typical of what you were under? Or were you on the edge to a treeline? I also wonder if you could obtain an RTK fix in that environment, or are all your shots post processed?
It was RTK. Mark, some places were alot worse. That was a typical environment.
My post process Base to Rover shots, are in the LS now, but the software at the JAVAD end is not available right now... as they are making changes, and re-writing some of it's stuff. I fully expect the RTK shots to be within a few hundredths of the RTK.
In super bad environments, the Javad will yield an answer, but sometimes it has a larger error ellipse. So far, the REAL coord is within the ellipse.
My first survey job was with the MI state DOT. Some of the survey trucks had a square drawn on the windshield just under the rearview mirror. (varied between 0.1' x 0.1' to 0.2' x 0.2', depending upon work ethic of the chief) The rule was that if 3 drops fell within the square within 30 seconds (or 1 minute, again, depending upon chief's work ethic), it was a rain day. Most other outfits I worked for had some similar threshold for declaring a rain day.
I moved to western WA in July 1990 and didn't see a drop of rain for a month and a half. It started raining sometime in September and didn't stop except for a few scattered days of false spring in mid-January. Most of the time it was a light to moderate rain, well beyond the 3 drops in the square test, but still light enough to remain productive. Around November/December, we had a few days when it rained so hard that it was very difficult to keep the scope clear enough to see through, heavy enough to interfere with getting a clear return beam for the EDM, and just tough to get anything done.
Knowing the weather reputation of the NW, I had refrained from asking the question until the end of an all-day downpour. Stupidly, but predictably from a relatively new guy from drier climes, I said "How hard does it have to rain before I should call it a rain day?" That bought several minutes of uproarious laughter and teasing the "rookie", but once that died down, the boss told me that if it's raining hard enough and blowing hard enough that the rain is falling sideways and upside down, and if it causes the instrument to shut down, then it's a rain day. I had thought that was an exaggeration meant as a joke until it actually happened a few weeks later. The answer was, there was almost no such thing as a rain day in western WA.
Later that winter, we had a day on which snow began falling around mid-morning and kept steady throughout the day. Being from colder climes, I recognized snow as just being a form of frozen rain. Having learned my lesson about rain days, and snow being easier to work in than rain, we kept going all day and got the job done, rolling into the shop about 4:30. As we brought the gear in, the boss comes out of his office and says "Where the hell have you been?"
"We've been on that boundary & topo you sent us to. What are you talking about?"
"IT'S SNOWING MAN! YOU CAN'T WORK IN THE SNOW!!!"
10" of rain in a day, and we were expected to work through it. 4" to 6" of snow and the whole region scurries for cover to wait out the storm. It was my turn to laugh uproariously.

Javad needs to design and sell something like this.

Before the days of electronic gadgets, the only true no field work days were those that there was lightning, the water was too high, or the roads were frozen over with ice and we could not get to the job.
That is still true for all my field work. First sign or crack of lightning and I am gone, even if it shows up on radar far away and headed my way.
After getting the first TS, with 3 drops of rain falling in an area the size of a brick and it went back into the box.

If it's not raining hard enough...drive faster!
That was my motto when employed by others 😉
A little rain doesn't stop us. Slows us down, keeps us out of the street but probably doesn't stop us. Wind is problematic when we're in the woods. If you ever saw the proverbial tree falling you know what I mean. Snow! That is why I left the land of cheese and sausages. We reserve the rainy days for those jobs where the client wants to follow us around.
Nate, http://www.covermatecovers.com/&apos ;">these might work to keep your box dry.
Didn't even know what a 'rain day' was until reading these posts. Only one time have I ever taken a break due to rain. Big thunderstorm rolled in as we were arriving on the job, clouds dark as night in the middle of the day. Minutes later thunder and lightning boomed and the skies opened up and it rained so hard you couldn't hear yourself think inside the cab of that truck. Looked at my I-man and said, 'I think we can wait a few minutes for this to blow over'. Fifteen minutes later it let up and the sun popped back out and away to work we went. Guess that's close as I've ever come to a rain day.
I'd be busting out the gun with all those trees around me Nate. That's got to be some wonder Javad gizmo you got there! (;
Just because I'm paranoid, doesn't mean they aren't out to get me.

Just put a clear plastic bag over it.
Mark, what was happening, is the rain was falling so fast, that there was a virtual water fall coming down the touch screen.
A little visor, and a rain gutter, is what it needs.

IF Javad would buy me a ticket, to Alaska, (3 days fishing included!) I'd come show it to you!

It's not the water causing the problem. It's the copious amounts of water!!

IF you used the Javad LS in the rain, you'd think a little differently, I think. Think of standing under a rain gutter, pouring so much rain, that you cannot see the screen well. And, big heavy drops pelting it, and actually pushing buttons. I am working on a little "Bill" for it.
Thing is, only need it a dozen times a year, or so.

After spending more to fix the total station than the total fee for the job I quit working in the rain. Everything is great.................until it ain't.
Nate, I dig your surveying style. Gettin' it done with modern, not widely used technology! I feel that you and your Javad are a testament to new and creative ways to get the job done that most folks have been taught to be skeptical about, much like a radial stakeout. Keep it up! As a guy up and coming in the industry this is the kind of stuff that keeps me fired up after a long week of monotony.
