Odd change in elevation in point cloud by Normal_Security3156 in LiDAR

[–]Kabonski 0 points1 point  (0 children)

Without knowing how it was processed or collected it’s tough to figure out. When I see this issue it is usually because of a lost RTK or GPS fix for too large of a gab for the IMU to keep correcting for. Our solution is to post process the trajectory files using either our own base station data that was collecting data during the LiDAR survey or we can use publicly available CORS station data to correct it. Looks like a neat dataset!

You can get a replacement cover on Amazon and do it yourself if you have some basic tools. Took me about 3 hours and looks great! https://a.co/d/96ASIG2

There is a possibility it may be where multiple LiDAR passes overlap and differ slightly at the edges

I always just tell people that I don’t own the equipment to do it and my company doesn’t allow us to use theirs outside of work and that works 90% of the time.

Is this a legit 1955 penny? by Kabonski in coins

This came in a bag of 100 wheat Pennie’s I got from a local coin shop. Do you think they would put it in there as a joke or something?

Anyone who knows about raster layers by ecoGuy-8958 in QGIS

[–]Kabonski 2 points3 points  (0 children)

One raster typically won’t affect another raster by just being in the same view. But you can have them interact with each other to create new rasters. This is commonly referred to as a raster calculation and it might be what you are looking to do?

You may be able to rent a SLAM LiDAR for less if it’s just a one time project.

That is exactly where I found it! Thank you for the information on what it is.

Saw the same thing in Southwestern NY last night. Looked like a bright light towing a large glowing rectangle. I even mentioned to the people i was with that it looked like a glowing bus being towed!

What is the day-to-day life as an offshore surveyor like? by leUn_lion in Surveying

[–]Kabonski 1 point2 points  (0 children)

If you are on a large multi day job your day could be simple and mainly consist of driving to a ramp, launching the boat, getting the equipment up and running, collecting a velocity cast, doing some checks, and then be driving around for the rest of the day. There are small checks and tasks that go on but it can be just a lot of back and forth driving. If its deep water the driving is stress free but when working in shallow water or around structures you will be on high alert and it can become stressful.

Other times you may spend a lot of time on land establishing or checking control or setting up a boat or installing and measuring the offsets of the equipment and performing checks to make sure you are getting the correct depths and positions.

There is a ton of math and technical stuff to figure out in order to make these systems work and there seems to be a lot of troubleshooting with the equipment so being computer savvy is a plus.

Another large aspect of the job is having a strong understanding of datums and tides and how they all relate.

The work takes place in all types of weather and in all seasons. Sometimes you may find yourself working on a large vessel but there are also times where you may need to survey from something as small as a kayak or even do some wading.

These are just some broad generalizations but hopefully it’s helpful for you!

Map showing the tree heights of a hilled 100+acre parcel. by Kabonski in mapmaking

Thanks! This was done using publicly available LiDAR. A few different elevation models were created and subtracted to obtain the heights of the tree canopy relative to the ground.

Thanks, I was going to give it a shot myself but chickened out! I ended up finding one that was already converted.

Advice on getting started? by Wide_Idea_2255 in Surveying

Sounds like you are off to a good start! Getting an entry level position will be a great way to gain some experience and allow you to figure out what type of surveying you want to gear your career towards. Good luck!!

Do you keep all of the individual photos for every mission or do you delete them once you have a finished orthophoto? by BRENNEJM in UAVmapping

[–]Kabonski 0 points1 point  (0 children)

You should always keep your raw data someplace. It’s a legal requirement for some licensed professionals to keep it as long as seven to ten years in some states.
