👀 Today, i tried something special : playing with lidar datas from IGN (Institut national de l'information géographique et forestière) 🎚️

First of all, you can see here a standard lidar file. Nice and creepy ^^ 😨

💡 But we have a solution. Not a good one if you want my opinion but...

We can pick an orthophoto of our terrain and use it to color all our points in the lidar file. Hard time using ... 🏜️

Here, you can see the image. I downloaded it from IGN again, extract the right size from the lidar

Here is a link to CloudCompare

But, here's the result :) And it's quite satisfying to have a result :D 🗺️

And a VIDEO ? YES

With QGIS, we can create a 3D view, and a video. You have it here. 🎥

There's 600 images generatded by QGIS then assembled with GIMP. Quite... hardtime again.

I don't know why i have map 3d map, and a second map just in the back. If someone can help :)

Back in Bremen after an intense Winter School learning stuff about and

Thanks for this awesome event.

http://www.gathers.eu/

Highly recommend attending such an event with very humble people in a very small field. Alas mostly unknown outside of their field. And hence it feels somewhat in crowd and I had odd feelings whether I fit in. But once you get rid of that feeling you can enjoy a very open community of a niche topic often overlooked.

Thanks for this!

The Case For Remote Sensing Of Individual Plants

https://doi.org/10.1002/ajb2.1347 <-- shared short article

# interpretation

aerial images - High-resolution images from the Planet Labs constellation of cube-sats detect flowering individual trees in the Peruvian Amazon (yellow objects in panel A) and Colombian Amazon (pink objects in panel B). Many thousands of flowering individuals are apparent across hundreds of kilometers of Amazonian forest in these flowering events. Scale bar = 500 m.
aerial and oblique remotesensing-created images - Drone remote sensing of individual trees. (A) Ultra-high-density drone lidar resolves individual tree structure in a temperate beech forest in the southern Czech Republic. Colors indicate elevation, and the tallest trees are about 40 m aboveground. Measurement density here is 4323 points per square meter. (B) High-spatial resolution optical remote sensing from a low-altitude drone in the Atlantic lowlands of Costa Rica. We used methods from computer vision to construct three-dimensional scene geometry from two-dimensional images. The image is a natural color composite. (C) Same area as B, but colored by surface elevation, where warmer colors indicate taller objects. A single Goethalsia meiantha crown is outlined in white. The area of this crown is 157.3 m2. At a pixel size of 1 cm, this crown contains 1.573 × 106 pixels, demonstrating the tremendous increase in measurement density at high-spatial resolution. Scale bar in B and C = 30 m.

I have some personal news to share. We're moving! As some of you already know, we have been working on a formerly abandoned homestead site, completely off-grid, with a small log cabin in the woods, for years now, trying to make it livable again. We are finally at the point where we can make this happen in the coming months. We are tentatively planning this for the summer.

For the first time in my life, really, I will no longer be an active chemist. The push and pull of going back into the office, where I am not needed, has reached a boiling point for me. I am resigning from the company I helped start and build and moving onto the next thing in my life as a forest farmer, dad and homeschool parent. Wish me luck. I've done one thing for the last 30+ years and now I'm going cold turkey away from it, to something pretty much the opposite.

I think I will be posting some about our successes and failures with the new adventure. Don't expect any pictures of us or anything. I have never found a picture of myself on the internet and there's not one of either of my boys. We're pretty private people, but, hopefully there'll be lots of nature photos along our trails and pictures of our soon-to-be plant based foods.

This year I am hoping to get some good information from the brilliant minds of Mastodon about a lot of things, including:

gardening. We have an ~800 sq ft, completely empty greenhouse. It has a large built in fan on one end, but no power. We have some solar panels on a hillside near it that are decades old, but still functional, that we are planning on repurposing to power the greenhouse along with the EcoFlow solar generators that we previously used to power the cabin before getting our permanent power up and running. Depending on how power hungry the motor is, we may need to add onto that. We'll see! I honestly don't know how many hours a day we'll need use the fans, for instance.

It's a blank slate, though. Zone 7b under the latest USDA map. Concrete floor. Otherwise completely empty. We have lots of thoughts about how best to use it, both to feed the family and have some left over. In the short term we would like to can and jar excess food, but we have plans to donate to the local community in the long term.

We have a year-round running spring at an appropriate elevation above it, but it would be quite the chore to collect and get that water to the greenhouse. We also have a year-round creek below it that we could conceivably pump water up from. We also have two boys who may end up running a lot of water around manually in the short term.

- I want our equipment to talk to our HomeKit in the end. While I don't intend to expand our HomeAssistant usage dramatically beyond that, I know that's how these things start and next thing you know you have 100 devices. It would be pretty cool to have greenhouse monitoring equipment as well.

Do I start a setup with something simple like the HomeAssistant Yellow if I don't want to spend a ton of time on this part of the plan?

It might be possible to get this to communicate to our new Rheem heat pump hot water heater, too, but that's the extent of our current HomeAssistant thoughts.

- We have some endangered native plants, as well as some cash crops growing both natively and intentionally planted in the forest as some test plots. Think ramps, ginseng, etc. but we are forest farming noobs.

We also have some test mushrooms going in log plugs that we intend to expand as we learn what works and what doesn't.

and - The state we are moving to has pretty decent LIDAR data of our property. I've played around with it quite a bit and made some fun maps. I was even able to find some hidden old logging roads that haven't been used in 100 years. I don't even know what I don't know in this area, but I'm planning to keep playing with it for data for the forest farming, running water from springs, etc.

I'm sure I'll add to this in a thread as we go and more things come up. It's all, honestly, terrifying and exhilarating at the same time at the moment, particularly for our boys who will be leaving the only home they've ever known this summer.

Also, wish me luck on my first ever public toot, I believe. I block and mute a lot of people anyway, so at least I know where those buttons are up front :)
